ABSTRACT
With the rapid increase in the number of MRP/MRPH implementations during the 1970s and 1980s, came the realization that many failed to meet expectations. Despite the growing body of research and experience this view was still held in the 1990s. A 1994 survey, 33 by Benchmark Research Ltd, of UK engineering companies with more than 200 employees and operating MRP systems less than three years old revealed that:
28% had no measures of the anticipated benefits prior to the start of the implementation
aside from the high number of respondents who had no prior definition of benefits, ‘at best l-in-4 do not achieve the expected benefits’
51% of implementations took longer than planned
28% of implementations were over budget
68% of packages were customized during implementation
56% did not have sufficient training to be able to fully use the system at GoLive.
