The requirements document is the official statement of what is necessary for the project, solution, system or IT software and/or hardware. It is not a design document. It shall set forth what the project, system, solution, software and/or hardware should do, rather than how it should do it. RFPs shall include both a definition and a specification of requirements as well as functional and technical data relating to those requirements. Refer to Chapter 8 and Chapter 12 of this manual for detailed instruction on developing successful requirements, specifications and statements of work. For the purpose of this chapter, a Requirements Verification Checklist is provided in Appendix E, as a quick reference only.
