Enterprise System
• Enterprise systems are software applications that have crossorganizational capabilities as opposed to department or groupspecific programs. They allow for collaboration and communication
across the organization through collection of data that is accessible
and usable by multiple departments.
2.1. Role of enterprise system in organization
Enterprise systems are a critical component of the process view of organizations.
They facilitate communication and coordination among different functions, and
they allow easy exchange of, and access to, data across the process. More
specifically, ES play a vital role in the following three areas:
• Execute the process
• Capture and store process data
• Monitor process performance
2.2. Execute the process
• Enterprise systems help organizations execute processes efficiently and
effectively
• Enterprise systems help execute processes by informing people when it is time to
complete a task, by providing the data necessary to complete the task, and in
some cases by providing the means to complete the task.
• Fulfilment process, for example, the system will inform people in the warehouse
that orders are ready for shipment and provide them with a listing of what
materials must be included in the order and where to find the materials in the
warehouse.
• Procurement process, the system generates the purchase requisitions and then
informs the purchasing department that they need to act on these requisitions
• Since organizations rely so heavily on ES, they must make certain that these
systems are functioning all the time so that the work is not interrupted.
Amazon.com
• Rather than manufacture its own products, Amazon.com purchases
and stores finished goods and then resells them to its customers
• The company receives most of their orders via their Web site
• This Web site is connected to an enterprise system that supports the
fulfilment process.
• When an order is received, the system communicates this information
to the warehouse, where the order is packed and shipped.
• If the online store stops working, then Amazon.com can’t take any
orders, and their entire warehouse will come to a stop
• 2.3. Capture and store process data
• Processes create data such as dates, times, product numbers, quantities,
prices, and addresses, as well as who did what, when, and where.
• Enterprise systems capture and store these data, commonly referred to as
process data or transaction data.
• Some of these data are generated and automatically captured by the
system whereas, other data are generated outside the system and must be
entered into it.
• In the fulfillment process, for example, when a customer order is received
(by mail or over the phone), the person taking the order must enter data
such as the name of the customer, what they ordered, and how much they
ordered.
• When the order is shipped, the warehouse will provide data about
what products were shipped and how many, whereas the system will
automatically include data related to who, when, and where.
• An important advantage of using an ES compared to a manual system
or multiple functional systems is that the data need to be entered
into the system only once. Once they are entered, they are easily
accessible to other people in the process.
• The data captured by an ES, along with data already in the system,
provide immediate feedback.
Amazon.com
• When a customer purchases something on Amazon.com, the system
provides a confirmation number that can be used to track the
progress of the order.
• In addition, the data in the current order are combined with historical
sales data to recommend additional products that may be of interest
to the customer—resulting in higher sales.
Evolution of ES
Stand-alone mainframe systems
• Components of an ES include hardware, software, and a database.
• hardware typically consisted of large, expensive mainframe computers.
• Software includes specialized operating system software needed to execute
operations from the applications on the hardware and custom applications
that provide capabilities needed to complete specific tasks
• Databases are used to store the data associated with the ES
• Only very large companies could afford to acquire and implement an ES
• the way users interacted with the ES was very primitive. They had to use a
terminal that was physically connected to the mainframe to input
commands to the system using punch cards.
• 1960s, 1970s, and 1980s, IBM was the only company that could
provide the mainframes, operating systems, and databases for the
early ES.
• major drawbacks of the mainframe architecture was its limited
scalability.
• Another limitation of the early ES was that they were custom
designed, meaning they were designed to address the specific needs
of individual firms.
Client-Server
Architecture
Client-Server Architecture
• Three layers of application :
• presentation layer : how you interact with the application (using
menus, typing selecting),
• application layer : what the application allows you to do (create
formulae or charts, compose an essay),
• data layer : where the application stores your work (on your hard
drive or flash drive).
• The three-tier client-server architecture separates these layers into
three separate components.
• Example : three-tier architecture is instant messaging (IM).
1. software we install in our computer is the presentation layer.
2. messaging system provides the application layer or the functionality (i.e.,
the ability to exchange messages with others)
3. data layer stores your login information, your contacts, and so on.
• Advantages :
1. achieve much greater scalability and flexibility because the different
layers can run simultaneously on different computers rather than
exclusively on a single mainframe.
2. ES can be run on considerably cheaper computers.
• Note : to maintain data integrity, each application server has to store its
records in a single database that resides on a separate server used solely
for the database
Service Oriented Architecture
• Service-Oriented Architecture (SOA) is a style of software design
where services are provided to the other components by application
components, through a communication protocol over a network.
• In SOA, a number of services communicate with each other, in one of
two ways: through passing data or through two or more services
coordinating an activity.
• SOA is accessed through Web Service.
• By using Web services, companies could now integrate several clientserver applications and create an enterprise mashup, or composite
applications.
• Example : if your company wants to see the map locations of every
customer in San Francisco, you could create a composite application
or mashup between the ES that contains your customer data and
Google Maps
• Web services provide a standardized and reliable way for multiple
systems to communicate in a very fast and scalable way to bring
added value and efficiency to a business process.
• By using SOA to integrate and expose the business processes and data
inside an ES, companies can now create new composite applications
quickly and inexpensively
• By using SOA to integrate and expose the business processes and data
inside an ES, companies can now create new composite applications
quickly and inexpensively
TYPES OF DATA IN ES
TRANSACTION DATA
MASTER DATA
ORGANIZATIONAL DATA
Transaction Data
• When an organization completes a specific process activity or task, the
data that it generates are transaction data
• Transaction data reflect the day-to-day activities of the organization
which are constantly changing.
• typically include general data such as who did what, when, and where,
as well as specialized data that relate to the specific task.
• Example: when a company sends a purchase order to a vendor, the
following transaction data are generated: dates, quantities, name of the
person requesting the material, name of the person approving the
material, prices, where the shipment is to be delivered, and the
shipment method.
Master Data
• Master data describe the key entities associated with an organization.
• Typical entities are vendors, products, and employees.
• These data change, but only occasionally.
• Eg : For products, master data include product number, description,
physical characteristics such as weight and colour, handling
requirements (e.g., fragile), and typical storage location. For
Employee master data include name, address, position data, payroll
data, tax-related data, and benefits data.
• Master data are not connected to a specific process or process step.
However, process steps require master data to be completed.
Organizational Data
• Organizational data describe central characteristics of organizations,
their internal structures and processes as well as their behavior.
• They rarely change over time.
• For example, Production regions of certain company may includes
multiple factories and each factories may have storage areas, shipping
points, and receiving points.
• All these data are organizational data and are included in the ES as
part of the configuration process.
• Configuration is the process of setting up the ES so it can support the
work of the business, that is, the business processes.
Customer Relationship
Management (CRM)
Types of
Enterprise
system
Enterprise Resource Planning
(ERP)
Supply Chain Management
Systems (SCM)
Enterprise Resource Planning (ERP)
• ERP integrates software applications, such as purchasing, finance, human
resources and inventory management.
• Within an ERP system, the integrated software modules, such as sales, quality
management and accounts receivable, communicate and share data.
• Each of these modules consists of multiple applications that execute end-to-end
business processes.
• For example, the sales module includes the applications necessary to create and
manage sales contracts, sales orders, sales invoices and sales order pricing.
• ERP may also be customized to support a number of different industries,
including oil and gas, retail and banking.
• Leaders in the ERP software industry include Oracle NetSuite, Microsoft Dynamics
365, SAP Business One.
Customer Relationship Management (CRM)
• CRM were developed to address the need to raise a sales department’s
productivity and provide an effective way to increase sales.
• With CRM functions, such as sales opportunity management, a company
learns more about its customers’ needs and buying behavior and combines
this information with market information to enhance the quality of the
company’s marketing plans and sales forecasts.
• CRM supports mass e-mail communications and automates the sales
process workflow to improve employee productivity.
• Leaders in the CRM software industry include Salesforce, Zoho and
HubSpot.
Supply Chain Management Systems (SCM)
• A supply chain is the collection of people, tasks, equipment, data and other
resources required to produce and move products from a vendor to a customer.
• Supply chain management refers to the management of supply chain activities in
an effective and efficient way to provide a company with a strategic advantage.
• These activities may include product development, material sourcing, production
and logistics as well as the information systems that coordinate these activities.
• Information flows allow supply chain partners to coordinate their strategic and
operational plans as well as the day-to-day flow of goods and materials through
the supply chain.
• The physical flows include the manufacture, transport and storage of goods or
materials.
• Leaders in the SCM software industry include SoftwareHut, E2open, IBM
Watson, Oracle E-Business Suite, and SAP.
SAP
