Study Notes

Functional Requirements

  • Define the services a system must provide.
  • Detail how the system responds to inputs.
  • Describe system behavior in various situations.
  • May specify what the system shouldn't do.

Non-functional Requirements

  • Restrict system services and functions.
  • Include time constraints, development process constraints, standards, and more.
  • Typically apply to the entire system, not individual features.

Domain Requirements

  • Impose constraints on the system based on the operational area.
