This section discusses information technology infrastructure and information
technology services, how information systems affect organizations, and the Internet
and organizations.
(1) Economic Impacts
IS/IT enables firms to lower their transaction costs and increase revenues
with fewer employees (transaction cost theory)
Agency theory suggests that IS/IT enables firms to reduce management
costs and increase revenues
(2) Organizational and Behavioral Impacts
IS/IT has moved decision-making to lower levels of management and managers make
decisions faster because information is readily available
(3) The Internet and Organizations
The Internet increases the accessibility, storage, distribution of information
and knowledge for business firms.
The Internet lowers the transaction and agency costs of firms.
Businesses are rapidly rebuilding their key business processes based on
Internet technology.
Section 3.4: Information Systems and Business Strategy.
Section 3.4 is one of the most critical sections in the text because it actually defines
strategy when it defines strategic information systems. Understanding business
strategy and how information systems can aid employees in making far-reaching and
deep-rooted decisions is critical to the long-range success of any corporation. “At the
business level of strategy, the key question is, ‘How can we compete effectively in
this particular market?’”
(1) Business strategy determines:
The products and services a firm produces
The industries in which the firm competes
Competitors, suppliers, and customers of the firm
Long-term goals of the firm
(2) IS can contribute to strategic objectives:
Operational excellence
New products, services, and business models
Customer and supplier intimacy
Improved decision making

(5) Porter’s Value Chain Model:
The value chain model looks at a business in terms of a set of primary and support
activities that add value to the firm’s products or services.
VC model can be used to determine where information systems have the most impact
to effect the competitive position of the firm
Firm gains a competitive advantage when it provides the product or service with more
value or the same value at a lower price
