章節(jié)摘錄

插圖：The benefits of the enterprise solutions approach include a single reposi-tory of data for all aspects of a business process and the flexibility of the modules. A single repository ensures more consistent and accurate data, aswell as less maintenance. The modules are flexible because additional modules can be added as needed once the basic system is in place. Added modules are immediately integrated into the existing system.  Enterprise solutions software also involves some disadvantages. Thesystems are complex, so implementation can take a long time to complete.Organizations typically do not have the necessary expertise in-house toimplement the systems, so they must rely on consultants or employees of the software vendor, which can be expensive. In some cases, organizations must change how they do business in order to benefit from a shift towardenterprise solutions.
