Core functionality Variables and parameters established so that the tests are repeatable and can be run at any time. Master and transactional data is created and passed sequentially from one test segment to the next. Core test run in about an hour. Equivalent manual tests would required more than a week for about 10 people. Large ERP projects must have a dynamic system development model.
System Testing Start with very small legacy file loads.
Program the load programs first. Senior management must know the status of the implementation. Project roles, methods of communication, tracking must be clearly defined. Processes in scope must be driven down to the transaction level and documented. Integrated scenarios must be developed and documented.
