Requirement Analysis

• SRS
  • Contract bt client & devs
  • What's in scope and out-of-scope
• Functional Requirements
  • Things software does
  • "This software shall..."
  • Atomic, precise, verifiable
  • eg:
    • The software shall display weather information for the next seven days
      • This is too vague! What's the location? What do you mean by weather?
    • Reqs are hard, waterfall is idealized
• Non-functional Requirements
  • Usability, performance
