- it's important that the user requirements are referred to throughout the whole cycle - if not then the system may not fully meet the needs of the end user
- must be completed before the design stage
DESIGN STAGE
- follows requirements specification defined in the investigation/anaylsis stage
- methods of data capture considered to ensure the format of he data capture and method of data capture to be used ared compatiable with the…
