<strong>in</strong> <strong>the</strong> supply cha<strong>in</strong> and <strong>the</strong> flow<br />

of <strong>in</strong>formation coord<strong>in</strong>ate <strong>the</strong><br />

activities <strong>in</strong>volved <strong>in</strong> buy<strong>in</strong>g, mak<strong>in</strong>g,<br />

and mov<strong>in</strong>g a product.<br />

and f<strong>in</strong>ished products, and distribut<strong>in</strong>g <strong>the</strong> f<strong>in</strong>ished products to customers. It l<strong>in</strong>ks manufactur<strong>in</strong>g<br />

plants, distribution centers, conveyances, retail outlets, people, and <strong>in</strong>formation<br />

through processes such as procurement or logistics to supply goods and services from source<br />

through consumption. Goods or services start out as raw materials and move through <strong>the</strong><br />

company’s logistics and production systems until <strong>the</strong>y reach customers. To manage <strong>the</strong> supply<br />

cha<strong>in</strong>, a company tries to elim<strong>in</strong>ate redundant steps, delays, and <strong>the</strong> amount of resources<br />

tied up along <strong>the</strong> way.<br />

Companies that skillfully manage <strong>the</strong>ir supply cha<strong>in</strong>s get <strong>the</strong> right amount of <strong>the</strong>ir products<br />

from <strong>the</strong>ir source to <strong>the</strong>ir po<strong>in</strong>t of consumption with <strong>the</strong> least amount of time and <strong>the</strong><br />

lowest cost. <strong>Information</strong> systems make supply cha<strong>in</strong> management more efficient by help<strong>in</strong>g<br />

companies coord<strong>in</strong>ate, schedule, and control procurement, production, <strong>in</strong>ventory management,<br />

and delivery of products and services to customers. <strong>Information</strong> systems can <strong>in</strong>tegrate<br />

demand plann<strong>in</strong>g, production forecast<strong>in</strong>g, materials requisition, order process<strong>in</strong>g, <strong>in</strong>ventory<br />

allocation, order fulfillment, transportation services, receiv<strong>in</strong>g, <strong>in</strong>voic<strong>in</strong>g, and payment.<br />

Table 2-7 describes how companies can benefit from us<strong>in</strong>g <strong>in</strong>formation systems for supply<br />

cha<strong>in</strong> management.<br />

Supply cha<strong>in</strong> management systems can be built us<strong>in</strong>g <strong>in</strong>tranets, extranets, or special supply<br />

cha<strong>in</strong> management software. The W<strong>in</strong>dow on Organizations shows how Hewlett-<br />

Packard benefited from a sophisticated supply cha<strong>in</strong> management system that used Internet<br />

technology.<br />

<strong>Enterprise</strong> <strong>Systems</strong><br />

A large organization typically has many different k<strong>in</strong>ds of <strong>in</strong>formation systems that support<br />

different functions, organizational levels, and bus<strong>in</strong>ess processes. Most of <strong>the</strong>se systems, built<br />

around different functions, bus<strong>in</strong>ess units, and bus<strong>in</strong>ess processes, do not “talk” to each o<strong>the</strong>r,<br />

and managers might have a hard time assembl<strong>in</strong>g <strong>the</strong> data <strong>the</strong>y would need for a comprehensive,<br />

overall picture of <strong>the</strong> organization’s operations. For <strong>in</strong>stance, sales personnel might not be<br />

able to tell at <strong>the</strong> time <strong>the</strong>y placed an order whe<strong>the</strong>r <strong>the</strong> items that were ordered were <strong>in</strong> <strong>in</strong>ventory;<br />

customers could not track <strong>the</strong>ir orders; and manufactur<strong>in</strong>g could not communicate eas-<br />
