ERP

If you are unfamiliar with ERP Enterprise Resource Planning, see ERP Life Cycle http://www.itjungle.com/tfh/tfh053105-story03.html for companies that are SUCCESSFUL at implementing ERP, and recognize that there are many failed implementations. The best measures of success are what kinds of standards are achieved by a company using an ERP, such as 100% accurate inventory, 0% past due to customers, or close to such goals.

See BPCS for an example of an ERP that runs on the AS/400 iSeries.
