information system (IS) as one that collects,
processes, stores, analyzes, and disseminates information for a specific purpose.
Each contains hardware, software, data, procedures, and people.
Data items refer to an elementary description of things, events, activities,
and transactions that are recorded, classified, and stored, but not organized to
convey any specific meeting.
Information is data that have been organized so that they have meaning
and value to the recipient. For example, a student’s grade point average is
information.
knowledge consists of data and/or information that have been
organized and processed to convey understanding, experience, accumulated
learning, and expertise as they apply to a current problem or activity. Data that
are processed to extract critical implications and to reflect past experiences and
expertise provide the recipient with organizational knowledge, which has a very
high potential value. Currently, knowledge management is one of the hottest topics
in the IT Field
end-user computing, in which analysts, managers,
and many other professionals can build and use systems on their
own desktop computers.
A transaction processing system (TPS) supports the monitoring, collection,
storage, processing, and dissemination of the organization’s basic business
transactions.
The TPS collects data continuously, frequently on a daily basis, or even in
real time (i.e., as soon as they are generated). Most of these data are stored in the
corporate databases and are available for processing.
Functional management information systems are put in place to ensure that business strategies come to
fruition in an efficient manner. Typically, a functional MIS provides periodic information about such
topics as operational
efficiency, effectiveness, and productivity by extracting information from databases and processing it
according to the needs of the user.
Cap 4
THE WORLD WIDE WEB
The World Wide Web—the Web—is the most widely used application on the Internet. The
Internet functions as the transport mechanism, and the Web (WWW, or W3) is an application
that uses those transport functions. Other applications also run on the Internet, with e-mail
being the most widely used.
Discovery – browser
Communication – chat, msn
Collaboration – Wikipedia, teleconferência, compartilhamento de telas.
intranet is a network designed to serve the internal informational needs of a company, using
Internet concepts and tools. It is a network confined to an organization for its internal use. It
provides easy and inexpensive browsing and search capabilities.
extranet connects the intranets of different organizations An extranet is an infrastructure
that allows secure communications among business partners over the Internet (using VPN).
It offers limited accessibility to the intranets of the participating companies, as well as the
necessary interorganizational communications, using Internet tools.
Software agents are computer programs that carry out a set of routine computer tasks on
behalf of the user and in so doing employ some sort of knowledge of the user’s goals.
A search engine (e.g., Altavista, Google) maintains an index of hundreds of millions of Web
pages and uses that index to find pages that match a set of user-specified keywords. Such
indexes are created and updated by software robots called softbots.
A directory (e.g.,Yahoo, About.com), on the other hand, is a hierarchically organized
collection of links to Web pages. Directories are compiled manually, unlike indexes, which are
generated by computers.
Frequently Asked Questions (FAQ) Agents.
The term data mining refers to sophisticated analysis techniques for sifting through large
amounts of information. Data mining permits new patterns and relationships to be discovered
through the use of software that can do much of the mining process
1. Same-time/same-place. In this setting, participants meet face-to-face in one place and
at the same time. An example is communication in a meeting room, which can be
electronically supported by group systems.
2. Same-time/different-place. This setting refers to a meeting whose participants are in
different places but communicate at the same time. A telephone conference call,
desktop videoconferencing, chat rooms, and instant messaging are examples of such
situations.
3. Different-time/same-place. This setting can materialize when people work in shifts.
The first shift leaves electronic or voice messages for the second shift.
4. Different-time/different-place. In this setting, participants are in different places, and
they send and/or receive messages (for example, via the Internet) at different times.

COLLABORATION
One of the abiding features of a modern organization is that people collaborate to perform
work. Collaboration refers to mutual efforts by two or more individuals who perform
activities in order to accomplish certain tasks.
The Nature of Group Work
The term workgroup refers to two or more individuals who act together to perform some
task. The group can be permanent or temporary. It can be in one location (face-to-face
meetings) or in several.
Virtual Collaboration
Virtual collaboration (or e-collaboration) refers to the use of digital technologies that enable
organizations or individuals to collaboratively plan, design, develop, manage, and research
products, services, and innovative IT and EC applications. Although e-collaboration can involve
noncommerce applications, the term usually refers to collaborative commerce—collaboration
among business partners.
COLLABORATIVE NETWORKS.
Barriers to E-Collaboration and C-Commerce
technical reasons involving integration, standards, and networks; security and privacy concerns over who
has access to and control of information stored in a partner’s database; internal resistance to information
sharing and to new approaches; and lack of internal skills to conduct collaborative commerce. New
approaches such as the use of XML and its variants and the use of Web Services could lessen
significantly the problem of standards.
4.5 COLLABORATION-ENABLING TOOLS: FROM WORKFLOW TO GROUPWARE
Workflow Technologies
Workflow is the movement of information as it flows through the sequence of steps that make up an
organization’s work procedures. Workflow management is the automation of workflows, so that
documents, information, or tasks are passed from one participant to another in a way that is governed by
the organizations rules or procedures. Workflow management involves all of the steps in a business
process from start to finish, including all exception conditions.
Groupware
Groupware refers to software products that support groups of people who share a common task or goal
and who collaborate on its accomplishment. These products provide a way for groups to share resources
and opinions. Groupware implies the use of networks to connect people, even if the people are in the
same room.
ELECTRONIC MEETING SYSTEMS.
ELECTRONIC TELECONFERENCING.
RTC TOOLS. The Internet, intranets, and extranets offer tremendous potential for real-time and
synchronous interaction of people working in groups. Realtime collaboration (RTC) tools help
companies bridge time and space to make decisions and to collaborate on projects. RTC tools
support synchronous communication of graphical and text-based information.
Interactive Whiteboards.
Screen Sharing
Instant Video.

Implementation Issues of Virtual Collaboration
E-LEARNING, DISTANCE LEARNING, AND TELECOMMUTING
E-Learning versus Distance Learning
E-learning refers to learning supported by the Web
when students work on the Web at home or in the classroom. It also can be done in virtual classrooms, in
which the entire coursework is done online and classes do not meet face-to-face, and then it is a part of
distance learning.
Distance learning (DL) refers to situations where teachers and students do not meet face-to-face.
e-learning is only one channel of distance learning. At the same time, some parts of e-learning are done in
the face-to-face mode, and not from a distance.
The Benefits of E-Learning
Online materials offer the opportunity to deliver very current content, of high quality, and consistent.
Students in e-learning situations have the flexibility of learning from any place, at any time, and at their
own pace. Finally, some learners in both educational and corporate settings appreciate what they perceive
as the risk-free environment offered by e-learning, in which they feel more free to express themselves
than in a face-to-face learning setting.
Virtual Universities
online universities from which students take classes from home or an off-site location via the Internet
Online Corporate Training
Web-based learning technologies allow organizations to keep their employees up-to-date, and
training via the Web can run 24 hours per day, every day (“24/7”).
Virtual Work and Telecommuting
Virtual (distributed) work environments refer to geographically distributed work teams, global project
teams, interorganizational teams, and nontraditional work environments such as virtual organizations,
satellite work centers, and telecommuting.
TELECOMMUTING. Telecommuting, or teleworking, refers to an arrangement
whereby employees can work at home, at the customer’s premises, in
special work places, or while traveling, usually using a computer linked to
their place of employment.
Impact on Individuals and Organizations. Telecommuting has a number of potential advantages for
employees, employers, and society. For example, the opportunity to work at home helps single parents
with young children or other homebound people assume more responsible managerial positions in
organizations. telecommuting also has some potential disadvantages. The major disadvantages for the
employees are increased feelings of isolation, loss of fringe benefits, lower pay (in some cases), no
workplace visibility, with in turn the potential of slower promotions, and lack of socialization. The major
disadvantages to employers are difficulties in supervising work, potential data security problems, training
costs, and the high cost of equipping and maintaining telecommuters’homes.
Telecommuting and Productivity.
The trip to work and a whole day at the office are not likely to make the worker feel any better, so he or
she stays home. Telecommuting also forces managers to manage by results instead of by overseeing.
SOME ETHICAL AND INTEGRATION ISSUES
Ethics on the Net
Several ethical, legal, and security issues have been raised as a result of
the use of electronic networks in general and the Internet in particular.
PRIVACY AND ETHICS IN E-MAIL.
RIGHT TO FREE SPEECH.
COPYRIGHT.
THE PRIVACY OF PATIENTS’ INFORMATION.
INTERNET MANNERS
Spamming refers to indiscriminate distribution of messages, without consideration for their
appropriateness. Spamming is a major problem online. Spamming is frequently answered by flaming,
which refers to sending angry messages.
UNSOLICITED ADVERTISING. An extension of spamming is the use of junk mail which may clog
providers’ systems and which frequently annoys people. Similarly, the use of pop-ups irritates many
people.
MONITORING EMPLOYEES’ USE OF THE INTERNET
Some companies use special software that monitors time spent on the Internet by each employee (and
by site address). The objective is to eliminate abuse of access during working hours and the accessing of
“indecent” sites.

Cap 5
Electronic commerce (EC) describes the process of buying, selling, transmitting, or exchanging
products, services, and information via computerized networks, primarily by the Internet
Electronic commerce (EC, or e-commerce) describes the process of buying, selling,
transferring, or exchanging products, services, and/or information via computer networks,
including the Internet.
E-business refers to a broader definition of EC, not just the buying and selling of goods and
services, but also servicing customers, collaborating with business partners, conducting elearning, and conducting electronic transactions within an organization.
(1) the product (service) sold, (2) the process, or (3) the delivery agent (or intermediary)
EC ORGANIZATIONS
Pure physical organizations (corporations) are referred to as brick-and-mortar (or oldeconomy) organizations, whereas companies that are engaged only in EC are considered
virtual (or pure-play) organizations.
Click-and-mortar (or click-and-brick) organizations are those that conduct some e-commerce
activities, yet their primary business is done in the physical world.
INTERNET VERSUS NON-INTERNET EC
Types of E-Commerce Transactions
Business-to-business (B2B): In B2B transactions, both the sellers and the buyers are business
organizations. The vast majority of EC volume is of this type.
● Collaborative
commerce (c-commerce): In c-commerce, business partners collaborate electronically.
Such collaboration frequently occurs between and among business partners along the supply chain.
● Business-to-consumers
●
(B2C): In B2C, the sellers are organizations, and the buyers are individuals.
Consumers-to-businesses (C2B): In C2B, consumers make known a particular need for a product or
service, and suppliers compete to provide the product or service to consumers. An example is
Priceline.com, where the customer names a product and the desired price, and Priceline tries to find
a supplier to fulfill the stated need.
● Consumer-to-consumer
(C2C): In C2C, an individual sells products or services to other individuals.
(C2C used as “customer-to-customer.”)
●
Intrabusiness (intraorganizational) commerce: In this case an organization uses EC internally to
improve its operations. A special case of this is known as B2E (business to its employees) EC, which
was illustrated in the opening case.
●
Government-to-citizens (G2C) and to others: In this case the government provides services to its
citizens via EC technologies. Governments can do business with other governments as well as with
businesses (G2B).
● Mobile
commerce (m-commerce): When e-commerce is done in a wireless environment, such as using
cell phones to access the Internet, we call it m-commerce.
EC Business Models
supported by infrastructure
People: Sellers, buyers, intermediaries, information systems specialists and other employees, and any
other participants.
● Public policy: Legal and other policy and regulating issues, such as privacy protection and taxation, that
are determined by the government.
● Marketing and advertising: Like any other business, EC usually requires the support of marketing and
advertising. This is especially important in B2C online transactions where the buyers and sellers usually
do not know each other.
● Support services: Many services are needed to support EC. These range from payments to order
delivery and content creation.
● Business partnerships: Joint ventures, e-marketplaces, and business partnerships of various sorts are
common in EC. These occur frequently throughout the supply chain (i.e., the interactions between a
company and its suppliers, customers, and other partners).
Benefits and Limitations/Failures of E-Commerce
5.2 E-COMMERCE MECHANISMS: AUCTIONS AND BARTERING
Auctions = leilões
Electronic Auctions (E-Auctions)
An auction is a market mechanism by which sellers place offers and buyers make sequential bids.
Forward auctions are auctions that sellers use as a selling channel to many potential buyers. Usually,
items are placed at sites for auction, and buyers will bid continuously for the items. The highest bidder
wins the items.
In reverse auctions, there is one buyer, usually an organization, that wants to buy a product or a service.
Suppliers are invited to submit bids. Online bidding is much faster than conventional bidding, and it
usually attracts many more bidders. Governments and large corporations frequently mandate this
approach, which may provide considerable savings.
Auctions are used in B2C, B2B, C2B, e-government, and C2C commerce, and they are becoming popular
in many countries.
Troca
Related to auctions is electronic bartering, the exchange of goods or services without a monetary
transaction. In addition to the individual-to-individual bartering ads that appear in some newsgroups,
bulletin boards, and chat rooms, there are several intermediaries that arrange for corporate e-bartering
5.3 BUSINESS-TO-CONSUMER APPLICATIONS
Electronic Retailing: Storefronts and Malls
e-commerce enables you to buy from home, and to do so 24 hours a day, 7 days a week shoppers can get
very detailed information on products, and can easily search for and compare competitors’products and
prices.
Electronic retailing (e-tailing) is the direct sale of products through electronic storefronts or electronic
malls, usually designed around an electronic catalog format and/or auctions.
ELECTRONIC STOREFRONTS. Hundreds of thousands of solo storefronts can be found on the Internet,
each with its own Internet name and EC portal. Called electronic storefronts, they may be an extension
of physical stores such as Home Depot, The Sharper Image, or Wal-Mart.
ELECTRONIC MALLS. An electronic mall, also known as a cybermall or emall, is a collection of
individual shops under one Internet address. The basic idea of an electronic mall is the same as that of a
regular shopping mall—to provide a one-stop shopping place that offers many products and services.
Each cybermall may include thousands of vendors. For example, shopping. yahoo.com and
eshop.msn.com include tens of thousands of products from thousands of vendors.
E-Tailing: The Essentials
The concept of retailing and e-tailing implies sales of goods and/or services to individual customers.
Issues in E-Tailing
Resolving channel conflict.
may face a conflict with its regular distributors when it sells directly online. Por exemplo obriga alguém
que está comprando um carro a terminar a compra numa concessionária.
Resolving conflicts within click-and-mortar organizations. When an established company decides to sell
direct online, on a large scale, it may create a conflict within its existing operations. Pode separar os dois
ou tentar juntá-los ganhando sinergia.
Organizing order fulfillment and logistics.
E-tailers face a difficult problem of how to ship very small quantities to a large number of buyers. This
can be a difficult undertaking, especially when returned items need to be handled.
IT-supported decision models can help with scheduling, routing, shipments, inventory management and
other logistics-related decisions.
Determining viability and risk of online e-tailers.
Many pure online e-tailers folded in 2000–2002, the result of problems with customer acquisition, order
fulfillment, and demand forecasting.
Identifying appropriate revenue models.
To succeed in EC, it is necessary to identify appropriate revenue models.
Service Industries Online
CYBERBANKING.
Electronic banking, also known as cyberbanking and online banking, includes various banking
activities conducted from home, a business, or on the road instead of at a physical bank location.
International and Multiple-Currency Banking.
International banking and the ability to handle trading in multiple currencies are critical for international
trade.
THE ONLINE JOB MARKET
The Internet offers a perfect environment for job seekers and for companies searching for hard-to-find
employees. The online job market is especially effective for technology-oriented jobs.
Job seekers.
Job seekers can reply to employment ads online.
Job offerers.
Many organizations advertise openings on their Web site. Others use sites ranging from Yahoo! to
bulletin boards of recruiting firms.
Recruiting firms.
Hundreds of job-placement brokers and related services are active on the Web. They use their own Web
pages to post available job descriptions and advertise their services in electronic malls and in others’ Web
sites. Recruiters use newsgroups, online forums, bulletin boards, and chat rooms. Job-finding brokers help
candidates write their resumes and get the most exposure.
TRAVEL SERVICES.
The Internet is an ideal place to plan, explore, and economically arrange almost any trip.
REAL ESTATE. Real estate transactions are an ideal area for e-commerce, for the following reasons.
First, you can view many properties on the screen, saving time for you and the broker. (corrector)
5.4 MARKET RESEARCH AND ONLINE ADVERTISING
A MODEL OF CONSUMER BEHAVIOR ONLINE
The purpose of a consumer behavior model is to help vendors understand how a consumer makes a
purchasing decision.
Independent (or uncontrollable) variables
Vendors’ controlled variables
The decision-making process dependent variables
The Consumer Decision-Making Process
A GENERIC PURCHASING-DECISION MODEL.
(1) need identification, (2) information search, (3) evaluation of alternatives, (4) purchase and delivery,
and (5) after-purchase evaluation.
A CUSTOMER DECISION MODEL IN WEB PURCHASING.
How Market Research FindsWhat Customers Want
ASKING CUSTOMERS WHAT THEY WANT
fill in electronic questionnaires.
TRACKING CUSTOMER ACTIVITIES ON THE WEB.
Today it is possible to learn about customers by observing their behavior on the Internet. Many
companies offer site-tracking services, based on cookies, Web bugs, or spayware programs.
Using Software Agents to Enhance B2C and Market Research
software agents are computer programs that conduct routine tasks, search and retrieve information,
support decision making, and act as domain experts. These agents sense the environment and act
autonomously without human intervention
Unlike search engines, an intelligent agent uses expert, or knowledge-based, capabilities to do more than
just “search and match.” For example, it can monitor movements on a Web site to check whether a
customer seems lost or ventures into areas that may not fit his profile, and the agent can then notify the
customer and even provide corrective assistance.
BRAND- AND VENDOR-FINDING AGENTS AND PRICE COMPARISONS.
Once the consumer has decided what to buy, a type of intelligent agent called a comparison agent will
help in doing comparisons, usually of prices, from different vendors.
The agent makes a recommendation based on your stated preferences.
SEARCH AGENTS.
can help customers determine what to buy to satisfy a specific need
The search agent helps consumers decide what product best fits their profile and requirements
COLLABORATIVE FILTERING AGENTS.
Use customer data to infer customer interest in other products or services
Advertising Online
Advertisement is an attempt to disseminate information in order to influence a buyer – seller transaction.
Internet advertising redefines the advertising process, making it media-rich, dynamic, and interactive. It
improves on traditional forms of advertising in a number of ways: Internet ads can be updated any time at
minimal cost, and therefore can always be timely. Internet ads can reach very large number of potential
buyers all over the world and they are sometimes cheaper in comparison to print (newspaper and
magazine), radio, or television ads.
ADVERTISING METHODS.
The most common advertising methods online are banners, pop-ups, and e-mails
Banners are, simply, electronic billboards, and banner advertising is the most commonly used form of
advertising on the Internet. Typically, a banner contains a short text or graphical message to promote a
product or a vendor.
Keyword banners appear when a predetermined word is queried from a search engine
Random banners appear randomly and might be used to introduce new products to the widest possible
audience, or for brand recognition
Pop-Up, Pop-Under, and Similar Ads. One of the most annoying phenomena in Web surfing is the
increased use of pop-up, pop-under, and similar ads.
E-Mail Advertising.
Electronic Catalogs and Brochures.
SOME ADVERTISING ISSUES AND APPROACHES.
Unsolicited Advertising: Spamming and More. A major issue related to popups and e-mail advertising
is spamming, the practice of indiscriminate distribution of electronic ads without permission of the
receiver
Permission Marketing. Permission marketing is one answer to e-mail spamming.
Permission marketing asks consumers to give their permission to voluntarily accept advertising and email.
Viral Marketing. Viral marketing refers to online word-of-mouth marketing.
The main idea in viral marketing is to have people forward messages to friends, asking them, for
example, to “check this out.”
Interactive Advertising and Marketing.
When the Internet is combined with databases marketing, interactive marketing becomes a very effective
and affordable competitive strategy.
Online Promotions: Attracting Visitors to a Site.
Making the top list of a search engine.
If it understands how a search engine’s program ranks its findings, a company can get to the top of a
search engine’s list merely by adding, removing, or changing a few sentences on its Web pages.
Online events, promotions, and attractions
People generally like the idea of something funny or something free, or both. Contests, quizzes, coupons,
and free samples are an integral part of e-commerce as much as, or even more than, they are in off-line
commerce.
5.5 B2B APPLICATIONS
In business to business (B2B) applications, the buyers, sellers, and transactions involve only
organizations. Business-to-business comprises about 85 percent of EC volume. It covers a broad spectrum
of applications that enable an enterprise to form electronic relationships with its distributors, resellers,
suppliers, customers, and other partners. By using B2B, organizations can restructure their supply chains
and partner relationship
Sell-Side Marketplaces
In the sell-side marketplace model, organizations attempt to sell their products or services to other
organizations electronically, from their own private emarket place and/or from a third-party site.
(1) electronic catalogs that can be customized for each large buyer and (2) forward auctions.
Buy-Side Marketplaces
The buy-side marketplace is a model in which organizations attempt to buy needed products or services
from other organizations electronically, usually from their own private e-marketplace. A major method of
buying goods and services in the buy-side model is a reverse auction.
E-PROCUREMENT. Purchasing by using electronic support is referred to as eprocurement.
In addition to reverse auctions just discussed, e-procurement uses other mechanism. Two popular ones
are group purchasing and desktop purchasing.
Group purchasing. In group purchasing, the requirements of many buyers are aggregated so that they
total to a large volume, and may merit more seller attention.
Desktop purchasing. In this variation of e-procurement, known as desktop purchasing, suppliers’
catalogs are aggregated into an internal master catalog on the buyer’s server, so that the company’s
purchasing agents (or even end users) can shop more conveniently.
Electronic
Exchanges
E-marketplaces in which there are many sellers and many buyers are called public exchanges (in short,
exchanges). They are open to all, and frequently are owned and operated by a third party.
5.6 INTRABUSINESS AND BUSINESS-TO-EMPLOYEES
Business to Its Employees (B2E) Commerce
Companies are finding many ways to do business electronically with their own employees. They
disseminate information to employees over the intranet, for example. They also allow employees to
manage their fringe benefits and take training classes electronically. In addition, employees can buy
discounted insurance, travel packages, and tickets to events on the corporate intranet, and they can
electronically order supplies and material needed for their work.
SALES FORCE AUTOMATION.
Sales force automation (SFA) is a technique of using software to automate the business tasks of sales,
including order processing, contact management, information sharing, inventory monitoring and control,
order tracking, customer management, sales forecast analysis, and employee performance evaluation.
E-Commerce Between and Among Units Within the Business
Large corporations frequently consist of independent units, or strategic business units (SBUs), which
“sell” or “buy” materials, products, and services from each other.
E-Commerce Between and Among Corporate Employees
Many large organizations allow employees to post classified ads on the company intranet, through which
employees can buy and sell products and services from each other.
5.7 E-GOVERNMENT AND CONSUMER-TO-CONSUMER EC
E-Government
E-government is the use of Internet technology in general and e-commerce in particular to deliver
information and public services to citizens, business partners and suppliers, and those working in the
public sector. It is also an efficient way of conducting business transactions with citizens and businesses
and within the governments themselves.
It improves the efficiency and effectiveness of the functions of government, including the delivery of
public services. It enables governments to be more transparent to citizens and businesses by giving access
to more of the information generated by government.
E-government also offers greater opportunities for citizens to provide feedback to government agencies
and to participate in democratic institutions and processes. As a result, e-government may facilitate
fundamental changes in the relationships between citizens and governments.
E-government applications can be divided into three major categories: government-to-citizens (G2C),
government-to-business (G2B), and government-to-government (G2G)
IMPLEMENTING E-GOVERNMENT.
Customerto-Customer E-Commerce
Customer-to-customer (C2C) e-commerce refers to e-commerce in which both the buyer and the seller
are individuals (not businesses). C2C is conducted in several ways on the Internet, where the best-known
C2C activities are auctions.
C2C AUCTIONS. Regardless where people are, in dozens of countries, selling and buying on auction sites
is exploding. Most auctions are conducted by intermediaries, like eBay.com.
CLASSIFIED ADS.
Internet-based classified ads have one big advantage over these more traditional types of classified ads:
They offer a national, rather than a local, audience.
PERSONAL SERVICES.
Numerous personal services are available on the Internet (lawyers, handy helpers, tax preparers,
investment clubs, dating services).
Some are in the classified ads, but others are listed in specialized Web sites and directories. Some are for
free, some for a fee. Be very careful before you purchase any personal services. Fraud or crime could be
involved.
SUPPORT SERVICES TO C2C.
When individuals buy products or services from individuals, they usually buy from strangers. The issues
of ensuring quality, receiving payments, and preventing fraud are critical to the success of C2C. One
service that helps C2C is payments by companies such as Paypal.com. Another one is escrow services,
intermediaries that take the buyer’s money and the purchased goods, and only after making sure that the
seller delivers what was agreed upon, deliver the goods to the buyer and the money to the seller (for a
fee).
5.8 E-COMMERCE SUPPORT SERVICES
Electronic Payments
Payments are an integral part of doing business, whether in the traditional way or online. Unfortunately,
in most cases traditional payment systems are not effective for EC, especially for B2B.
ELECTRONIC PAYMENT SYSTEMS. As in the traditional marketplace, so too in cyberspace, diversity of
payment methods allows customers to choose how they wish to pay. The following instruments are
acceptable means of electronic payment: electronic checks, electronic credit cards, purchasing cards,
electronic cash, stored-value cards, smart cards, and person-to-person payments.
Electronic checks.
Electronic credit cards.
Purchasing Cards
Electronic Cash.
SECURITY IN ELECTRONIC PAYMENTS.
Security Requirements. Security requirements for conducting EC are the following:
1.
Authentication. The buyer, the seller, and the paying institutions must be assured of the identity
of the parties with whom they are dealing.
2.
Integrity. It is necessary to ensure that data and information transmitted in EC, such as orders,
reply to queries, and payment authorization, are not accidentally or maliciously altered or
destroyed during transmission.
3.
Nonrepudiation. Merchants need protection against the customer’s unjustified denial of placing
an order. On the other hand, customers need protection against merchants’ unjustified denial of
payments made. (Such denials, of both types, are called repudiation.)
4.
Privacy. Many customers want their identity to be secured. They want to make sure others do
not know what they buy. Some prefer complete anonymity, as is possible with cash payments.
5.
Safety. Customers want to be sure that it is safe to provide a credit card number on the Internet.
They also want protection against fraud by sellers or by criminals posing as sellers.
Security Protection. Several methods and mechanisms can be used to fulfill the above requirements. One
of the primary mechanisms is encryption, which is often part of the most useful security schemes.
E-Wallets. E-wallets (or digital wallets) are mechanisms that provide
security measures to EC
purchasing. The wallet stores the financial information of the buyer, including credit card number,
shipping information, and more.
Thus, sensitive information does not need to travel on the Net, and the buyer and seller save time. The
problem is that you need an e-wallet with each merchant.
Virtual Credit Cards. Virtual credit cards are a service that allow you to shop with an ID number and a
password instead of with a credit card number. They are used primarily by people who do not trust
browser encryption sufficiently to use their credit card number on the Internet.
Payment Using Fingerprints. An increasing number of supermarkets allow their regular customers to pay
by merely using their fingerprint for identification.
A computer template of your fingerprint is kept in the store’s computer system. Each time you shop, your
fingerprint i smatched with the template at the payment counter. You approve the amount which is then
charged either to your credit card or bank account.
Order Fulfillment
5.9 LEGAL AND ETHICAL ISSUES IN E-BUSINESS
Ethical standards and their incorporation into law frequently trail technological innovation. E-commerce
is taking new forms and enabling new business practices that may bring numerous risks—particularly for
individual consumers—along with their advantages.
Market Practices and Consumer and Seller Protection
When buyers and sellers do not know each other and cannot even see each other (they may even be in
different countries), there is a chance that dishonest people will commit fraud and other crimes over the
Internet. During the first few years of EC, the public witnessed many of these, ranging from the creation
of a virtual bank that disappeared along with the investors’ deposits, to manipulation of stock prices on
the Internet. Unfortunately, fraudulent activities on the Internet are increasing.
FRAUD ON THE INTERNET
BUYER PROTECTION. Buyer protection is critical to the success of any commerce where buyers do not
see the sellers, and this is especially true for e-commerce.
SELLER PROTECTION. Sellers, too, may need protections. They must be protected against consumers
who refuse to pay or who pay with bad checks, and from buyers’ claims that the merchandise did not
arrive. They also have the right to protect against the use of their name by others, as well as to protect the
use of their unique words and phrases, slogans, and Web address (trademark protection).
PRIVACY. Most electronic payment systems know who the buyers are; therefore, it may be necessary to
protect the buyers’ identities. Another privacy issue may involve tracking of Internet user activities by
intelligent agents and “cookies” (a string of characters stored on the user’s hard drive to record the history
of the user’s visits to particular Web sites). A privacy issue related to employees also involves tracking:
Many companies monitor employees’ e-mail and have installed software that performs in-house
monitoring of Web activities. Yet many employees don’t want to feel like they are under the watchful eye
of “Big Brother,” even while at work.
WEB TRACKING. By using tracking software, companies can track individuals’movements on the
Internet. Programs such as “cookies” raise a batch of privacy concerns.
DISINTERMEDIATION. The use of EC may result in the elimination of some of a company’s employees
as well as brokers and agents. This result is called disintermediation—that is, eliminating the
intermediary.
Legal Issues Specific to E-Commerce
DOMAIN NAMES. Internet addresses are known as domain names. Domain names appear in levels. A
top-level name is wiley.com or stanford.edu. A secondlevel name will be wiley.com/turban or ibm.com.hk
(for IBM in Hong Kong). Toplevel domain names are assigned by central nonprofit organizations that
check for conflicts and possible infringement of trademarks. the URL matches the company’s name.
Problems arise when several companies that have similar names compete over a domain name.
Cybersquatting. Cybersquatting refers to the practice of registering domain names in order to sell them
later at a higher price.
DISINTERMEDIATION AND REINTERMEDIATION.
TAXES AND OTHER FEES.
Federal, state, and local authorities are scrambling to figure out how to get a piece of the revenue created
electronically.
COPYRIGHT. Intellectual property, in its various forms, is protected by copyright laws and cannot be
used freely.
5.10 FAILURES AND STRATEGIES FOR SUCCESS
E-Commerce
Failures
PRE-INTERNET FAILURES.
No standards were established for submitted documents.
● There was resistance to change to the new system, and the FDA did not force reviewers to work
electronically.
● The
system was merely an electronic version of existing documents. No business process reengineering
(BPR) was undertaken in planning (or improving) the new system.
● The
FDA lacked technical expertise in interorganizational information systems and in collaborative
commerce.
● No
training or even information was provided to the FDA’s end users.
● There
were learning curve difficulites, and no time was allowed to learn different document systems.
● Clients
(the pharmaceutical companies) were not encouraged to make electronic submissions.
● There
was no IS planning. The FDA knew that a business process design study was needed, but it did
not do it.
INTERNET-RELATED EC FAILURES
incorrect business model.
insufficient number of buyers
too much competition, low prices
lack of cash
customer acquisition cost was too high
lack of second-round funding
income was insufficient to convince investors to fund it further.
FAILED EC INITIATIVES.
Success Stories and Lessons Learned
Thousands of brick-and mortar companies are slowly adding online channels with great success.
“Analyze the opportunities, go out to look, keep it focused, start small (one thing at a
time), and aim at market leadership”
select robust business models, understand the dot-com future, foster e-innovation, carefully evaluate a
spin-off strategy, co-brand, employ exdot-com staffers, and focus on the e-generation as your market
Many experts (e.g., The National Institute for Standards and Technology, NIST) recommend contingency
planning and preparing for disasters
add value, focus on a niche and then extend that niche, maintain flexibility, get the technology right,
manage critical perceptions, provide excellent customer service, create effective connectedness, and
understand Internet culture.
Conclusion
Analyzing successful companies, researchers have suggested that if they do careful planning to reach
profitability quickly, many click-and-mortar companies are likely to succeed. Joint ventures and
partnerships are very valuable, and planning for satisfactory infrastructure and logistics to meet high
demand is needed. In short, do not forget that e-business has a “business” side!
1.
Managing resistance to change. Electronic commerce can result in a fundamental change in
how business is done, and resistance to change from employees, vendors, and customers may
develop. Education, training, and publicity over an extended time period offer possible solutions
to the problem.
2.
Integration of e-commerce into the business environment. E-commerce needs to be integrated
with the rest of the business. Integration issues involve planning, competition for corporate
resources with other projects, and interfacing EC with databases, existing IT applications, and
infrastructure.
3.
Lack of qualified personnel and outsourcing. Very few people have expertise in e-commerce.
There are many implementation issues that require expertise, such as when to offer special
promotions on the Internet, how to integrate an e-market with the information systems of buyers
and sellers, and what kind of customer incentives are appropriate under what circumstances. For
this reason, it may be worthwhile to outsource some e-commerce activities.
4.
Alliances. It is not a bad idea to join an alliance or consortium of companies to explore ecommerce. Alliances can be created at any time. Some EC companies (e.g., Amazon.com) have
thousands of alliances. The problem is which alliance to join, or what kind of alliance to form
and with whom.
5.
Implementation plan. Because of the complexity and multifaceted nature of EC, it makes sense
to prepare an implementation plan. Such a plan should include goals, budgets, timetables, and
contingency plans. It should address the many legal, financial, technological, organizational, and
ethical issues that can surface during implementation.
6.
Choosing the company’s strategy toward e-commerce. Generally speaking there are three major
options: (1) Lead: Conduct large-scale innovative ecommerce activities. (2) Watch and wait: Do
nothing, but carefully watch what is going on in the field in order to determine when EC is
mature enough to enter it. (3) Experiment: Start some e-commerce experimental projects (learn
by doing). Each of these options has its advantages and risks.
7.
Privacy. In electronic payment systems, it may be necessary to protect the identity of buyers.
Other privacy issues may involve tracking of Internet user activities by intelligent agents and
cookies, and in-house monitoring of employees’ Web activities.
8.
Justifying e-commerce by conducting a cost-benefit analysis is very difficult. Many intangible
benefits and lack of experience may produce grossly inaccurate estimates of costs and benefits.
Nevertheless, a feasibility study must be done, and estimates of costs and benefits must be made.
9.
Order fulfillment. Taking orders in EC may be easier than fulfilling them. To learn about the
problems and solutions related to order fulfillment.
10. Managing the impacts. The impacts of e-commerce on organizational structure, people,
marketing procedures, and profitability may be dramatic. Therefore, establishing a committee or
organizational unit to develop strategy and to manage e-commerce is necessary.
E-commerce can be conducted on the Web, by e-mail, and on other networks. It is divided into the following major
types: business-to-consumer, consumer-to-consumer, business-to-business, e-government, collaborative commerce,
and intrabusiness. In each type you can find several business models.
_ E-commerce offers many benefits to organizations, consumers, and society, but it also has limitations
(technological and nontechnological). The current technological limitations are expected to lessen with time.
_ A major mechanism in EC is auctions. The Internet provides an infrastructure for executing auctions at lower cost,
and with many more involved sellers and buyers, including both individual consumers and corporations.
Two major types exist: one for selling, which is the traditional process of selling to the highest bidder (forward
auctions), and one is for buying, using a tendering system of buying at the lowest bid (reverse auctions).
_ A minor mechanism is online bartering, in which companies arrange for exchange of physical items and/or
services.
_ The major application areas of B2C commerce are in direct retailing, banking, securities trading, job markets,
travel, and real estate. Several issues slow the growth of B2C, notably channel conflict, order fulfillment, and
customer acquisition. B2C e-tailing can be pure (such as Amazon.com), or part of a click-andmortar organization.
_ Direct marketing is done via solo storefronts or in malls. It can be done via electronic catalogs, or by using
electronic auctions. Understanding consumer behavior is critical to e-commerce. Finding out what customers want
can be determined by asking them, in questionnaires, or by observing what they do online. Other forms of market
research can be conducted on the Internet by using intelligent agents.
_ Like any commerce, EC requires advertising support, much of which can be done online by methods such as
banner ads, pop-ups, and customized ads. Permission marketing, interactive and viral marketing, electronic catalogs,
making it to the top of search-engine listings, and online promotions offer ways for vendors to reach more customers.
The major B2B applications are selling from catalogs and by forward auctions, buying in reverse auctions and in
group and desktop purchasing, and trading in exchanges.
_ Most organizations employ B2B collaborative commerce, usually along the supply chain.
_ EC activities can be conducted inside organizations. Three types are recognized: between a business and its
employees, between units of the business, and among emloyees of the same organizations. Many method and tools
exist in conducting the above.
_ E-government commerce can take place between government and citizens, between businesses and governments,
or among government units. It makes government operations more effective and efficient.
_ EC can also be done between consumers (C2C), but should be undertaken with caution. Auction is the most
popular C2C mechanism.
_ Traditional, nonelectronic payment systems are insufficient or inferior for doing business on the Internet.
Therefore, electronic payment systems are used. Electronic payments can be made by e-checks, e-credit cards, e-cash,
stored-value and smart cards, electronic bill presentment and payment, and e-wallets.
_ Order fulfillment is especially difficult in B2C, making B2C expensive at times.
Protection of customers, sellers, and intellectual property is a major concern, but so are the value of contracts, domain
names, and how to handle legal issues in a multicountry environment.
There is increasing fraud and unethical behavior on the Internet, including invasion of privacy by sellers and misuse
of domain names. Both sellers and buyers need to be protected. Periods of innovations produce both many successes
and many failures. There have been many of both in e-commerce.
Major reasons for failure are insufficient cash flow, too much competition, conflicts with existing systing systems,
wrong revenue models, and lack of planning. Despite the failures, overall EC volume is growing exponentially.

CAP 8
8.1 ESSENTIALS OF THE SUPPLY AND VALUE CHAINS
6.1 - Fundamentos das Cadeias de Suprimento de Valor
6.3 - Sistemas Computadorizados> MRP, MRP II, ERP e SCM
Initially, the concept of a supply chain referred only to the flow of materials from their sources (suppliers)
to the company, and then inside the company to places where they were needed. There was also
recognition of a demand chain, which described the process of taking orders and delivering finished
goods to customers.
Soon it was realized that these two concepts are interrelated, so they were combined under the single
concept named the extended supply chain, or just supply chain.
supply chain refers to the flow of materials, information, payments, and services from raw material
suppliers, through factories and warehouses, to the end customers. A supply chain also includes the
organizations and processes that create and deliver products, information, and services to the end
customers. It includes many tasks such as purchasing, payment flow, materials handling, production
planning and control, logistics and warehousing, inventory control, and distribution and delivery.
SUPPLY CHAIN MANAGEMENT. The function of supply chain management (SCM) is to plan,
organize, and coordinate all the supply chain’s activities.
SCM SOFTWARE. SCM software refers to software intended to support specific segments of the supply
chain, especially in manufacturing, inventory control, scheduling, and transportation. This software
concentrates on improving decision making, optimization, and analysis.
E-SUPPLY CHAIN. When a supply chain is managed electronically, usually with Web-based software, it
is referred to as an e-supply chain.
SUPPLY CHAIN FLOWS
Materials flows. These are all physical products, new materials, and supplies that flow along the chain
Information flows. All data related to demand, shipments, orders, returns, schedules, and changes in the
above are information flows.
Financial flows. Financial flows include all transfers of money, payments, credit card information and
authorization, payment schedules, e-payments, and credit-related data.
The Components of Supply Chains
(1) upstream, where sourcing or procurement from external suppliers occur, (2) internal, where
packaging, assembly, or manufacturing take place, and (3) downstream, where distribution or dispersal
take place, frequently by external distributors.
reverse logistics, which is the return of products. For the automaker, that would be cars returned to the
dealers in cases of defects or recalls by the manufacturer.
Types of Supply Chains
Integrated make-to-stock, continuous replenishment, build-to-order, and channel assembly
The Supply Chain and the Value Chain
8.3 COMPUTERIZED SYSTEMS: MRP, MRPII, SCM, AND INTEGRATION
The Evolution of Computerized Supply Chain Aids
Historically, many of the supply chain activities were managed with paper transactions, which can be
very inefficient. Therefore, since the time when computers first began to be used for business, people
have wanted to automate the processes along the supply chain.
reduce cost, expedite processing, and reduce errors
material requirements planning (MRP) model was devised. This model essentially integrates
production, purchasing, and inventory management of interrelated product. It became clear that computer
support could greatly enhance use of this model, which may require daily updating. This resulted in
commercial MRP software packages coming on the market.
manufacturing resource planning (MRP II), which adds labor requirements and financial planning to
MRP
integration of functional information systems. This evolution continued, leading to the enterprise
resource planning (ERP) concept, which integrates the transaction processing and other routine activities
of all functional areas in the entire enterprise. ERP initially covered all routine transactions within a
company, including internal suppliers and customers, but later it was expended to incorporate external
suppliers and customers in what is known as extended ERP software.
Systems Integration
functionally oriented. Functional systems may not let different departments communicate with each other
in the same language.
benefits of systems integration
●
Tangible benefits: inventory reduction, personnel reduction, productivity improvement, order
management improvement, financial-close cycle improvements, IT cost reduction, procurement cost
reduction, cash management improvements, revenue/profit increases, transportation logistics cost
reduction, maintenance reduction, and on-time delivery improvement.
●
Intangible benefits: information visibility, new/improved processes, customer responsiveness,
standardization, flexibility, globalization, and business performance.
TYPES OF INTEGRATION: FROM SUPPLY TO VALUE CHAIN.
Internal integration refers to integration between applications, and or between applications and databases,
inside a company. For example, one may integrate the inventory control with an ordering system, or a
CRM suite with the database of customers.
External integration refers to integration of applications and/or databases among business partners. An
example of this is the suppliers’ catalogs with the buyers’ e-procurement system. External integration is
especially needed for B2B and for partner relationship management (PRM) systems
The integrated value chain is a more encompassing concept. It is the process by which multiple
enterprises within a shared market channel collaboratively plan, implement, and (electronically as well as
physically) manage the flow of goods, services, and information along the entire chain in a manner that
increases customer-perceived value. This process optimizes the efficiency of the chain, creating
competitive advantage for all stakeholders in the value chain. Whereas the supply chain is basically a
description of flows and activities, the value chain expresses the contributions made by various segments
and activities both to the profit and to customers’ satisfaction.
Another way of defining value chain integration is as a process of collaboration that optimizes all internal
and external activities involved in delivering greater perceived value to the ultimate customer. A supply
chain transforms into an integrated value chain when it does the following:
● Extends the chain all the way from subsuppliers (tier 2, 3, etc.) to customers
● Integrates back-office operations with those of the front office
● Becomes highly customer-centric, focusing on demand generation and customer service as well as
demand fulfillment and logistics
● Seeks to optimize the value added by information and utility-enhancing Services
Is proactively designed by chain members to compete as an “extended enterprise,” creating and enhancing
customer-perceived value by means of cross-enterprise collaboration

7.1 7.2 e 7.3 – Processamento transacional
The idea the DHMC chose was to connect wireless handheld devices with a purchasing and inventory
management information system. The medical center has a wireless LANs (Wi-Fi) into which handhelds
are connected. Information about supplies then can be uploaded and downloaded from the devices to the
network from anywhere within the range of the Wi-Fi. In remote clinics without Wi-Fi, the handhelds are
docked into wireline network PCs.
IT can support the routine processes of inventory management, enabling greater efficiency, more focus on
core competencies, and greater satisfaction for employees and management. The new system also helped
to modernize and redesign some of the center’s business processes, and was able to support several
business processes (e.g., operations, finance, and accounting), not just one.
CRM – Customer relationship management
7.1 FUNCTIONAL INFORMATION SYSTEMS
integrated approach that keeps the functional departments as they are, but creates an integrated
supportive information system to help communication, coordination, and control.
Porter’s Value Chain Model and the Supply Chain
The value chain model views activities in organizations as either primary (reflecting the flow of goods
and services) or secondary (supporting the primary activities). The organizational structure of firms is
intended to support both of these types of activities. Figure 7.2 maps the major functional departments
onto the value chain structure.
the supply chain is a business process that links all the procurement from suppliers, the transformation
activities inside a firm, and the distribution of goods or services to customers via wholesalers and
retailers.
Major Characteristic of Functional Information Systems
Composed of smaller systems. A functional information system consists of several smaller information
systems that support specific activities performed in the functional area.
Integrated or independent. The specific IS applications in any functional area can be integrated to form a
coherent departmental functional system, or they can be completely independent. Alternatively, some of
the applications within each area can be integrated across departmental lines to match a business process.
Interfacing. Functional information systems may interface with each other to form the organization-wide
information system. Some functional information systems interface with the environment outside the
organization. For example, a human resources information system can collect data about the labor market.
Supportive of different levels. Information systems applications support the three levels of an
organization’s activities: operational, managerial, and strategic.
7.2 TRANSACTION PROCESSING INFORMATION SYSTEMS
The core operations of organizations are enabled by transaction processing systems.
Computerization of Routine Transaction Processes
the information system that supports these transactions is the transaction processing system (TPS). The
transaction processing system monitors, collects, stores, processes, and disseminates information for all
routine core business transactions. These data are input to functional information systems applications, as
well as to decision support systems (DSS), customer relationship management (CRM), and knowledge
management (KM). The TPS also provides critical data to e-commerce, especially data on customers and
their purchasing history.
Transaction processing occurs in all functional areas. Some TPSs occur within one area, others cross
several areas (such as payroll).
Objectives of TPS
The primary goal of TPS is to provide all the information needed by law and/or by organizational
policies to keep the business running properly and efficiently.
Specifically, a TPS has to efficiently handle high volume, avoid errors due to concurrent operations, be
able to handle large variations in volume (e.g., during peak times), avoid downtime, never lose results,
and maintain privacy and security.
To meet these goals, a TPS is usually automated and is constructed with the major characteristics listed in
Table 7.1
Activities and Methods of TPS
First, data are collected by people or sensors and entered into the computer via any input device.
Generally speaking, organizations try to automate the TPS data entry as much as possible because of the
large volume involved.
Next, the system processes data in one of two basic ways: batch or online processing. In batch
processing, the firm collects data from transactions as they occur, placing them in groups or batches. The
system then prepares and processes the batches periodically (say, every night). Batch processing is
particularly useful for operations that require processing for an extended period of time. Once a batch job
begins, it continues until it is completed or until an error occurs. In online processing, data are processed
as soon as a transaction occurs.
online transaction
master files- containing key information about important business entities
transaction files - containing information about activities concerning these business entities, such
as orders placed by customers, are also held in online files until they are no longer needed for everyday
transaction processing activity. This ensures that the transaction data are available to all applications, and
that all data are kept up-to-the-minute.
The entire process is managed by a transaction manager
The flow of information in a typical TPS is shown in Figure 7.3. An event, such as a customer purchase,
is recorded by the TPS program. The processed information can be either a report or an activity in the
database. In addition to a scheduled report, users can query the TPS for nonscheduled information (such
as, “What was the impact of our price cut on sales during the first five days, by day?”). The system will
provide the appropriate answer by accessing a database containing transaction data.
Web-Based and Online Transaction Processing Systems
In online transaction processing (OLTP), transactions are processed as soon as they occur.
With OLTP and Web technologies such as an extranet, suppliers can look at the firm’s inventory level or
production schedule in real time.
OLTP has broadened to become interactive Internet TPS. Internet transaction processing software and
servers allow multimedia data transfer, fast response time, and storage of large amount of graphics and
video—all in real time and at low cost. The interactivity feature allows for easy and fast response to
queries. OLTP also offers flexibility to accommodate unpredictable growth in processing demand
(scalability) and timely search and analysis of large databases.
7.3 MANAGING PRODUCTION/OPERATIONS AND LOGISTICS
The production and operations management (POM) function in an organization is responsible for the
processes that transform inputs into useful outputs (see Figure 7.4). In comparison to the other functional
areas, the POM area is very diversified and so are its supporting information systems. It also differs
considerably among organizations. For example, manufacturing companies use completely different
processes than do service organizations, and a hospital operates much differently from a university.
In-House Logistics and Materials Management
Logistics management deals with ordering, purchasing, inbound logistics (receiving), and outbound
logistics (shipping) activities. In-house logistics activities are a good example of processes that cross
several primary and support activities in the value chain. Both conventional purchasing and eprocurement result in incoming materials and parts. The materials received are inspected for quality and
then stored. While the materials are in storage, they need to be maintained until distributed to those who
need them. Some materials are disposed of when they become obsolete or their quality becomes
unacceptable.
INVENTORY MANAGEMENT. Inventory management determines how much inventory to keep.
Overstocking can be expensive; so is keeping insufficient inventory.
Three types of costs play important roles in inventory decisions: the cost of maintaining inventories, the
cost of ordering (a fixed cost per order), and the cost of not having inventory when needed (the shortage
or opportunity cost). The objective is to minimize the total of these costs.
Two basic decisions are made by operations: when to order, and how much to order.
QUALITY CONTROL. Manufacturing quality-control systems can be stand-alone systems or can be part
of an enterprise-wide total quality management (TQM) effort. They provide information about the quality
of incoming material and parts, as well as the quality of in-process semifinished and finished products.
Such systems record the results of all inspections. They also compare actual results to metrics. Qualitycontrol data may be collected by Web-based sensors and interpreted in real time, or they can be stored in
a database for future analysis. Periodic reports are generated (such as percentage of defects, percentage of
rework needed), and management can compare performance among departments on a regular basis or as
needed.
Planning Production/Operations
MATERIAL REQUIREMENTS PLANNING (MRP). Inventory systems that use an EOQ approach are
designed for those individual items for which demand is completely independent (for example, the
number of chairs a furniture manufacturer will sell).
The software that facilitates the plan for acquiring (or producing) parts, subassemblies, or materials in the
case of interdependent items is called material requirements planning (MRP). MRP is computerized
because of the complex interrelationship among many products and their components, and the need to
change the plan each time that a delivery date or the order quantity is changed.
MANUFACTURING RESOURCE PLANNING (MRP II). A POM system called manufacturing resource
planning (MRP II) adds functionalities to a regular MRP.
For example, in addition to the output similar to that of MRP, MRP II determines the costs of parts and
the cash flow needed to pay for parts. It also estimates costs of labor, tools, equipment repair, and energy.
Finally, it provides a detailed, computerized budget for the parts involved.
JUST-IN-TIME SYSTEMS. Just-in-time (JIT) is an approach that attempts to minimize waste of all kinds
(of space, labor, materials, energy, and so on) and to continuously improve processes and systems. For
example, if materials and parts arrive at a workstation exactly when needed, there is no need for
inventory, there are no delays in production, and there are no idle production facilities or underutilized
workers.
PROJECT MANAGEMENT. A project is usually a one-time effort composed of many interrelated
activities, costing a substantial amount of money, and lasting for weeks or years. The management of a
project is complicated by the following characteristics.
● Most projects are unique undertakings, and participants have little prior experience in
● Uncertainty exists due to the generally long completion times.
● There can be significant participation of outsiders, which is difficult to control.
● Extensive interaction may occur among participants.
● The many interrelated activities make changes in planning and scheduling difficult.
● Projects often carry high risk but also high profit potential.
the area.
The essence of these tools is to break complex projects or operations into a sequence of events, to
examine the relationships among these events, and to schedule these events to minimize the time needed
to complete the project.
WORK MANAGEMENT SYSTEMS. Work management systems (WMS) automatically manage the
prioritization and distribution of work. These systems deal with resource allocation, an activity that is
missing from workflow systems. For example, if an operator is unavailable, WMS recalculates the process
and reallocates human resources to meet the business need.
TROUBLESHOOTING. Finding what’s wrong in the factory’s internal operations can be a lengthy and
expensive process. Intelligent systems can come to the rescue. Bizworks, from InterBiz Solutions, is an
example of a successful software product that tackles thorny POM problems, such as interpretation of
data gathered by factory sensors. The product is useful for quality control, maintenance management, and
more.
Computer-Integrated Manufacturing
Computer-integrated manufacturing (CIM) is a concept or philosophy that promotes the integration of
various computerized factory systems. CIM has three basic goals: (1) the simplification of all
manufacturing technologies and techniques, (2) automation of as many of the manufacturing processes as
possible, and (3) integration and coordination of all aspects of design, manufacturing, and related
functions via computer hardware and software.
Product Lifecycle Management (PLM)
Product lifecycle management (PLM) is a business strategy that enables manufacturers to control and
share product-related data as part of product design and development efforts and in support of supply
chain operations
PLM is a big step for an organization, requiring it to integrate a number of different processes and
systems. Ultimately, its overall goal from the organization’s point of view is to move information through
an organization as quickly as possible in order to reduce the time it takes to get a product to market and to
increase profitability.
Resuminho:
Sistemas de Informação Funcionais:
- Tradicionalmente, sistemas de informação desenhados por área funcional (eficiência) ? Esta pode não
ser a melhor estrutura (processos entre diversas áreas).
- Reestruturar a organização, com times entre áreas: Não resolve problemas de falta de coordenação ou
cadeia de suprimentos não efetiva.
- Integrar um sistema de informação de suporte.
- Características de Sistemas de Informação Funcionais:
- Composto de sistemas menores.
- Integrado ou independente.
- Interface.
- Suporte em diferentes níveis (operacional, gerencial e estratégico).
Processamento Transacional:
- TPS (Sistema de Processamento de Transações): Monitora, coleta, armazena, processa e dissemina
informação para todas as transações rotineiras do núcleo de um negócio.
- Ocorre em todas as áreas funcionais.
- Objetivos:
- Prover informação necessária por lei ou pelas políticas da organização para que o negócio corra
apropriada e eficientemente.
- Deve lidar com alto volume de dados e alta variação no volume, evitar erros causados por operações
concorrentes, evitar indisponibilidade, nunca perder resultados, e manter privacidade e segurança.
- Prover operações eficientes para a organização, garantir acurácia e integridade de dados e informação,
aumentar vantagem competitiva.
- Atividades e métodos de TPS:
- Processamento batch: coleta de dados transacionais, agrupando-os e executando-os periodicamente.
Usado quando o processamento requer tempo.
- Processamento online: execução ocorre à medida que os dados são coletados.
- OLTP (Online Transaction Process): Processamento online que requer arquitetura cliente-servidor.
- Web-Based Interactive Transaction Processing: TPS interativa na Internet.
Gerenciamento de Produção, Operações e Logística:
- POM (Production and Operations Management): Responsável pelo processo que transforma entradas
em saídas úteis.
- Gerenciamento de Logística e Materiais: Lida com pedidos, compras, recebimento e envio.
- Gerenciamento de Inventório: Determina quanto deve ser mantido no inventório, auxiliando na decisão
de custo de manter inventórios, no custo de realizar um pedido e no custo de não ter o pedido quando
necessário.
- Controle de Qualidade: Podem ser sistemas independentes ou TQM (Total Quality Management,
relativo à empresa inteira).
Planejamento de Produção e Operações:
- MRP (Material Requirements Planning): Facilita o planejamento de aquisição ou produção de
materiais.
- MRP II: (Manufacturing Resource Planning) MRP com funcionalidades como finanças (custos de
partes, mão-de-obra, ferramentas, reparo de equipamentos e energia).
- JIT (Just-in-Time Systems): Minimizar desperdício de recursos e melhorar processos e sistemas.
- Gerenciamento de Projetos: Ferramentas como PERT e CPM quebram a complexidade de projetos ou
operações em uma seqüência de eventos, para examinar o relacionamento entre estes e elaborar um
cronograma minimizando o tempo necessário.
- WMS (Work Management Systems): Gerencia a priorização e distribuição de trabalho.
- CIM (Computer-Integrated Manufacting): Conceito que promove a integração de vários sistemas
computadorizados da fábrica, visando simplificação de tecnologias e técnicas, automação de processos, e
integração e coordenação de todos os aspectos de design, manufatura e funções relacionadas.
- Modelo CIM: Definição de processos e produtos, planejamento e controle de manufatura, automação da
fábrica, gerenciamento de informação.
- Planejamento integrado: Comunicação, compartilhamento de dados e cooperação.
- Vantagens: Compreensão e flexibilidade.
- PLM (Product Lifecycle Management): Controla e compartilha dados relacionados ao produto como
parte do design do produto.
- Benefícios em mudanças de engenharia, tempo do ciclo, reuso de design e produtividade.

Ter informações que permitem entender a empresa.
Acumula tudo o que a empresa já fez.
Possui dados externos também.
Data Warehouse têm informações de um período para trás (é o volume que limita). Não serve
para fazer o operacional da empresa.
O operacional é em tempo corrente.
Outras empresas podem ter um operacional
Metadados qualificam os dados.
Operacional não tem data warehouse.
Informacionais estão ligados ao middlewares.
Escolha dois: (custo, qualidade, tempo)
Sistemas analíticos ficam entre Data Warehouse e Data Mart. Eles geram conhecimento. Tiram
informação de coisas que não têm informação. Ex: Data Mining. Descobre o modelo, descobre
tendências.
Ele descobre que aumenta vendas em dias de chuva.
Sistema analítico é o que mais se aproxima de sistemas inteligentes.
Front-end do BI é informacional. O cruzamento de dados é analítico.

Q1 – Qual a importância que o Planejamento Estratégico de TI tem para uma empresa? Sabese que a implantação do mecanismo de Planejamento de TI traz benefícios e dificuldades.
Quais seriam esses benefícios e dificuldades? Que políticas (normas e diretrizes) relativas a
esse assunto você recomendaria para uma empresa que pretende adotá-lo?
Recursos escassos.
Plano ter credibilidade.
Diretriz, se o mandachuva não estiver por trás, já era (stakeholders).
Tem que ter um método.
Tem que surgir a necessidade.
Propósitos, quem está envolvido, quando é feito, qual é o ritmo. Fazem normas,
recomendações.
Q2 – Considere dois sistemas típicos de empresas: um minerador de dados (data mining) e um
de vendas na Internet. No que um sistema se distingue do outro, tanto do ponto de vista
conceitual e funcional quanto do ponto de vista de implantação?
Data Mine é analítico
Sistema de vendas é transacional gera dados para o Data Mine.
Erro no Data Mine pode acabar com a estratégia
Data Mine é mais complexo e caro.
