Summary of requirements
You are recommended to start with a high level summary of the requirements. As you get into the detail the document becomes bulky and complex. It is useful if at any stage you can go back to the start and see the overview. You should define the high level functions under the four headings of:
input
management
output
collaboration/business process management
You should also define the phases of the preferred implementation plan and assign departments and user numbers to each phase. You should then point to where additional requirements are defined for each function and phase. We generally define the overall functional requirements first and then the specific requirements for each phase.
