"PIRRIDM" is an acronym derived as follows:

  • There are four basic components to requirements:
    • Processes, which identifies how work is done within an organization.
    • Information, which identifies what is needed to get work done in an organization.
    • Rules, which identify the goals and limitations of the work that is done in an organization.
    • Relationships, which identify how the first three components fit together to get work done in an organization.
  • There are three techniques that a business analyst normally uses to define requirements:
    • Identify what is to be included in the Components.
    • Document the contents of the Components.
    • Maintain the contents of the Components.
