Which of the following statements about ERP system is true?

Explanation

An ERP suite is not one monolithic program: it is a family of interoperating modules — manufacturing, materials management, human resources, finance, resource planning and so on — sharing a common database, so statement 2 is the accurate description. Statement 1 is false because seamless integration is an ideal that most real implementations only partly reach. Statement 3 is false since integration can be achieved in several ways (single-vendor suite, best-of-breed with middleware, custom interfaces). Statement 4 is false because uniform enterprise-wide implementation produces tight, rigid coupling rather than very flexible connections. Hence option 2.
