Evaluating the Impact of Electronic Business Systems: Lessons Learned from Three Cases at the Defense Logistics Agency

摘要

This article synthesizes our experience evaluating three electronic business (eBusiness) systems in the Defense Logistics Agency. The focus was on actual impact in real life operational sellings. We summarize our experience in terms of lessens learned and make a case that our experience can help ethers do similar evaluation. Lessens learned are grouped into six categories: metrics and data sources, methodology, program logic, adaptive systems, realistic expectations, and dependencies among the previous five.
