Business vs. Functional Requirements
Essential processes may be accomplished in many different ways.
Essential processes document WHAT the business need is.
Functional requirements further describe HOW the process should be accomplished.
- Accept a customer payment
- Accept payment via Web
- Accept payment via Phone
- Accept payment via Mail
Why do we not include how the process is performed in business requirements?
- You may end up going down the wrong path for a solution
- You don’t want to limit yourself to what the solution could be
