Chapter 1
1.0 Introduction to Information Systems
-
-
-
Information is most important resource to companies.
1980’s: most job losses were in blue collar VS now: most losses are white collar
management jobs
Global spending on IT: 3.8 trillion in 2019 VS spending on management consulting
services: 160 billion
Communication is increasingly carried out through: email, online conferencing,
international teleconferencing.
o Internet technologies have become essential tools.
IT innovations: cloud computing, mobile digital platforms, AI, machine learning,
robotics
New business models are new ways for creating value for customers and making
revenue.
o E.g., Netflix offered a new business model in entertainment + streaming.
o E.g., Uber, Airbnb
E-commerce expansion: COVID-19, mobile technology development has helped ecommerce (EC) to expand faster than ever before.
Management changes: management is using social media, business intelligence, and
analytics to improve relations with customers, suppliers, and employers,
Firms + organization changes: organizations are more flattened than before; middle
management levels are being eliminated because of the growth of decision support
systems.
Globalization:
o (+) Provides companies with opportunities of outsourcing of resources for lower
costs.
o (-) Greater competition for jobs, markets, resources, ideas.
o (-) Growing interdependence on global economies.
o (-) Requires new skill markets, opportunities.
Emerging digital firms: significant business relationships are digitally enabled.
o Core business processes are accomplished through digital networks.
o Key corporate assets are managed digitally.
o Offer greater flexibility in organization + management.
o Time-shifting + space-shifting allow businesses to be conducted at any
time/place.
o Ideally suited for global operations which take place in remote locations, different
time zones
1.1 IT & Business Strategies
-
Organizations + IT interdependence: mutual relationship between IT strategy +
business strategy.
-
-
o In contemporary systems, there is a growing interdependence between firm’s IS +
business capabilities. Changes in strategy, rules, business processes increasingly
require changes in hardware, software, databases, telecommunications.
o What the organization would like to do depends on what its system will permit.
 Businesses need to invest in IT to do what they would like to do.
 Having significant IT platform can impact business strategies.
Strategic business objectives:
o Operational excellence: IS are most important tools for managers to achieve
higher levels of efficiency + productivity in business operations.
 E.g., Walmart stores are linked to suppliers for efficient inventory,
procurement processes through a network.
o New products, services, business models
o Customer + supplier intimacy: when businesses know their customers well +
respond accordingly, customers respond by purchasing more.
 Similarly, when business engage suppliers, the better the suppliers can
provide vital inputs.
 E.g., JC Penny’s IS digitally link the suppliers to each of its stores
o Improved decision making: IS allows managers to use real-time data.
o Competitive advantage: IS helps companies to perform better than competitors,
charge less for superior products, respond to customers/suppliers in real time.
 E.g., Toyota, Walmart
o Survival: IS have become necessities
 E.g., Citibank was the first bank to offer ATM services; other banks had to
follow
E-commerce: limited to buying/selling goods + services on networks.
E-business: includes e-commerce + broad range of tasks (e.g., coordinating customer
training seminars)
1.2 Introduction to Supply Chain
-
Supply chain (SC): involves everybody from customer to last supplier.
o Key flows: information, product, cash
o Management of flows is key to success.
Original equipment manufacturer: company that supplies components that are used in
the production of goods by other manufacturers.
Pull (make-to-order) SC model: execution is initiated in response to a customer order,
reactive.
Push SC model: execution is initiated in anticipated (i.e., forecasting) of customer
orders, speculative.
Supply chain macro-processes
o Supplier relationship management (SRM): source, negotiate, buy, design
collaboration, buy, design collaboration, supply collaboration
o Integrated supply chain management (ISCM): strategic planning, demand
planning, supply panning, fulfillment, field service
o Customer relationship management (CRM): market, price, sell, call center,
order management.
-
Supply chain objectives: final objective is maximizing net value generated by SC.
o This can be achieved through optimization of transportation, inventory levels,
utilization of resources using engineering methods.
Supply chain decisions: information flow, products, inventories, supplier selections,
funds
o Decisions may be categorized as: design, planning, operational

2.0 Global E-Business + Collaboration
-
-
-
-
-
Organization of IS:
o Four types: executive support systems (ESS), decision support systems (DSS),
management information systems (MIS), transaction processing systems (TPS)
o Three organizational levels: strategic, management, operational
Transaction processing system (TPS): basic business system that serves organizations’
operational levels.
o Input: any transaction or event
o Processing: sorting, listing, merging, updating
o Output: detailed lists, reports, summaries
Management information system (MIS):
o Input: summary transaction data, high volume data, simple models (e.g., rations,
visualizations)
o Processing: simple models, low-level analysis
o Output: summaries, graphical outputs
Decision support Systems (DSS): serve management level data analysis for making
decisions.
o Used by middle managers for: supplier selection, aggregate planning,
maintenance prediction, etc.
o Input: MIS + TPS data (could be low or massive amount of data)
o Processing: sensitivity analysis, simulations
o Output: special reports, decision analyses, query responses
Executive support systems (ESS): rely on accurate inputs from MIS, DSS, TPS
o Input: internal MIS, DSS, TPS data + external data of customers, market,
suppliers, etc.
o Output: projections, query responses
o Digital dashboards with real-time view of financial performance are a critical
feature.
2.1 Business Processes
-
E.g., checking product for quality in manufacturing + production, selling product in sales
+ marketing, paying creditors in finance + accounting, evaluating job performance in
human resources
Order fulfillment:
-
-
-
-
o Three levels: sales, accounting, manufacturing + production
 Sales: generate order, submit order
 Accounting: check credit, approve credit, generate invoice
 Manufacturing + production: assemble product, ship product
Enterprise application: IS that serves business processes.
o Used to coordinate + integrate information used in TPS, DSS, MIS, ESS
o Pull information from many parts of the firm at different organizational levels +
suppliers, customers.
o Four types: enterprise resource planning (ERP), customer relationship
management (CRM), supply chain management (SCM), knowledge management
systems (KMS)
Enterprise resource planning (ERP): optimize utilization of resources of business firms
through an integrated, consolidated system.
Supply chain management system (SCM): automate flow of information between
firms, suppliers to optimize production + delivery.
o Goal: move products as efficiently as possible.
 Optimize SC resources.
 Manage relationships.
 Manage shared information.
 Automate flow of information across organizational boundaries.
o Inter-organizational systems
o SCMS must be designed with business processes of potential partners +
businesses in mind.
Customer relationship management systems (CRMS): important for sales, marketing,
customer service.
o Goals: improve customer satisfaction, increase customer retention, identify +
retain most profitable customers, increase sales, optimize revenue
Knowledge management systems (KMS): useful for helping firms’ employees to
understand how to perform certain business processes or how to solve problems.
o Knowledge management cycle: process of transforming information into
knowledge within an organization which explains how knowledge is captured,
processed, and distributed.
 Link internal to external sources of knowledge.
 Manage processes for capturing + applying knowledge + expertise.
 Collect + make knowledge available to improve business processes +
decisions.
2.2 Information Systems for Global Collaboration
