The document outlines the key phases in an ERP lifecycle implementation process. It begins with pre-evaluation and screening of potential ERP packages. Next, a package is selected and a project plan is created, followed by a gap analysis. Then processes are reengineered and the system is configured. Teams are trained and testing is conducted before going live. Post-implementation, end users are trained and the system is maintained. The lifecycle highlights the stages all organizations go through when implementing an integrated ERP system.
