Centralized, Decentralized
and Distributed• Development of large mainframe computers
and telecommunications networks and
terminals caused a centralization of computer
hardware and software, databases, and
information specialists at the corporate level of
organization.
• Next, the development of minicomputers andmicrocomputers accelerated a downsizing
trend, which prompted a move back toward
decentralization by many business firms.

• Distributed client/server networks at the
corporate, department, workgroup, and team
levels came into being, which promoted a shift
of databases and information specialists to
some departments and the creation ofinformation centers to support end-user and
workgroup computing.

• Supplier’s proposal sent electronically to
purchasing organization.
• Electronic contract approved over network.
• Supplier manufactures and packages goods,
attaching shipping data recorded on a bar
code.
• Quantities shipped and prices entered in
system and flowed to invoicing program;
invoices transmitted to purchasing
organization
• Manufacturer ships order.

interenterprise system that uses information
technology to help support and manage the
links between some of a company’s key
business processes and those of its suppliers,
customers, and business partners.

relationships, or supply chain , to get a

• Once that is done, end users and IS managers
can move on to developing the portfolio of
business applications needed to support
business/IT strategies; the hardware, software,
and Internet-based technology platforms tosupport those applications; the data resource
management methods to provide necessary
