Enterprise Systems

Enterprise systems (ES) are large-scale organizational systems built around packaged enterprise system software. Enterprise system software (ESS) • is a set of packaged application software modules with an integrated architecture, which can be used by organizations as their primary engine for integrating data, processes and information technology, in real time, across internal and external value chains; • contains deep knowledge of business practices accumulated from vendor implementations in a wide range of client organizations; • is a generic ‘semi-finished’ product with tables and parameters that user organizations and their implementation partners must configure, customize and integrate with other computer based information systems to meet their business needs.

ENTERPRISE SYSTEMS appear to be a dream come true. These commercial software packages promise the seamless integration of all the information flowing through a company - financial and accounting information, human resource information, supply chain information, customer information. For managers who have struggled, at great expense and with great frustration, with incompatible information systems and inconsistent operating practices, the promise of an off-the-shelf solution to the problem of business integration is enticing. It comes as no surprise, then, that companies have been beating paths to the doors of enterprise-system developers. The sales of the largest vendor, Germany's SAP, have soared from less than $500 million in 1992 to approximately $3.3 billion 1997, making it the fastest-growing software company in the world. SAP's competitors, including such companies as Baan, Oracle, and PeopleSoft, have also seen rapid growth in demand for their packages. It is estimated that businesses around the world are now spending $10 billion per year on enterprise systems-also commonly referred to as enterprise resource planning, or ERP, systems-and that figure probably doubles when you add in associated consulting expenditures. While the rise of the Internet has received most of the media attention in recent years, the business world's embrace of enterprise systems may in fact be the most important development in the corporate use of information technology in the 1990s. But are enterprise systems living up to companies' expectations? The growing number of horror stories about failed or out-of-control projects should certainly give managers pause. FoxMeyer Drug argues that its system helped drive it into bankruptcy. Mobil Europe spent hundreds of millions of dollars on its system only to abandon it when its merger partner objected. Dell Computer found that its system would not fit its new, decentralized management model. Applied Materials gave up on its system when it found itself overwhelmed by the organizational changes involved. Dow Chemical spent seven years and close to half a billion dollars implementing a mainframe-based enterprise system; now it has decided to start over again on a client-server version. Some of the blame for such debacles lies with the enormous technical challenges of rolling out enterprise systems - these systems are profoundly complex pieces of software, and installing them requires large investments of money, time, and expertise. But the technical challenges, however great, are not the main reason enterprise systems fail. The biggest problems are business problems. Companies fail to reconcile the technological imperatives of the enterprise system with the business needs of the enterprise itself. An enterprise system, by its very nature, imposes its own logic on a company's strategy, organization, and culture. It pushes a company toward full integration even when a certain degree of business unit segregation may be in its best interests. And it pushes a company toward generic processes even when customized processes may be a source of competitive advantage. If a company rushes to install an enterprise system without...
