POOR DUMP SAP LET BE THE LESSON Lessons for ERP Systems … "Those who fail to learn history are doomed to repeat it" (Winston Churchill) In the field of MIS, “issues seen as ‘new’ turn out to have long roots” (Keen, 1991) What of ERP Systems ? – ERP systems are large scale, expensive projects – ERP systems may involve dramatic changes to work practices and organisational processes – They are not “quick fix” solutions and need to be implemented with care

It’s All About the Requirements ! “In nearly every software project that fails to meet performance and cost goals, requirements inadequacies play a major and expensive role in project failure” (Alford & Lawson, 1979) “The hardest single part of building a software system is deciding precisely what to build. No other part of the conceptual work is as difficult as establishing the detailed technical requirements... No other part of the work so cripples the resulting system if done wrong.” (Brooks, 1987) Build the correct system (product) + Build the system correctly (process)
