The document discusses the failed ERP implementation by Hershey's, called Enterprise 21. The $112 million project aimed to integrate SAP, Manugistics, and Seibel software by 1999 but faced major issues. Post-implementation, order fulfillment doubled to 15 days and inventories grew by 25% with a 0.5% loss in market share. Key failure factors included unrealistic timelines, inadequate testing and training, and attempting a "big bang" go-live for the entire system. Hershey's was able to recover by upgrading more gradually in parts with improved testing, training, and a new CIO. The case highlights lessons about properly scoping ERP projects and change management.
