    ERP II: Theextended enterprise system F.C. “Ted” Weston, Jr. Professor of Computer Information Systems, Colorado State University, Fort Collins, Colorado (tweston@lamar.colostate.edu) M edium and large companies are quickly learning that integrating electronic systems within and between physical locations is, more and more, a required element of doing business. At the same time, real-time communications and integration with both customers and vendors is a growing business requirement. In all cases, information technology (IT) drives the fundamental collaboration and integration changes taking place in industry. To date, much of the business transformation driven by IT is led by companies in the United States; however, this trend of information integration across extended enterprise systems will soon be embraced by firms regardless of where they are located and independent of the geographic addresses of business partners, plants, sales offices, customers, and/or vendors. Physical borders will have less future business relevance except for issues of governance, taxes, and security. IT is With IT as the infrastructure, rapidly propelling enterprise systems beyond simply en- abling change to become the drivers of business change. business is coming to rely on The cost of developing an IT infrastructure is also well real-time information integration documented. Weill, Subramani, and Broadbent (2002) both within and between firms and report that the average firm spends more than 4.2 percent of annual revenue on IT, accounting for more than 50 without regard to geography, borders, percent of its total capital expenditure budget.
