Standish Report vs Problems encountered Standish ReportOur Problems Lack of User involvement Incomplete Requirements Lack of feedback from customers. Unrealistic Expectations Unclear Objectives Lack actual system understanding. Changing requirementsChange in customer representatives Unrealistic time frame Schedule limitations

Proposed Solutions Involve users throughout the requirements gathering process Involve users throughout the requirements gathering process Have users attend reviews and receive incremental feedback from users Have users attend reviews and receive incremental feedback from users Give realistic expectations Give realistic expectations To solve communication issues, employ specialists in business or system analysis To solve communication issues, employ specialists in business or system analysis

What we have learnt from this project Requirements are not obvious Requirements are not obvious To understand the customers wants/needs To understand the customers wants/needs To distinguish requirements and design To distinguish requirements and design Documentation traceability is important Documentation traceability is important To work as a team To work as a team
