Analyze Requirements

The analyze requirements phase is the next step in IEPD development.

You graphically defined your scenario. Now you need to define your business rules and requirements, which define the exchange as well as the expectations of the exchange.

Business Rules

Business rules are specific qualifications for data that refer to how it should be structured (e.g., field length, constraints).

A student’s enrollment status is not available or is unknown. The assumption is they are not enrolled, and an information-needed flag will be added by setting X element to the value of 1.

Business Requirements

Business requirements are the drivers for an information exchange that are primarily operational or functional requirements.

The verification service shall respond only to search requests issued by the client application, the Verification Information System (VIS).

Follow a formal process to define and validate business requirements and accurately document an information exchange:

1. Initiate the requirements process.
   • Prepare and plan.
   • Perform an analysis.
2. Define the exchange requirements.
   • Gather user requirements.
   • Define security and privacy requirements.
   • Specify exchange requirements.
3. Prepare requirements for design.
   • Analyze requirements.
   • Verify and validate requirements.
