sdd-spec

A delta specification documents specific additions, modifications, and removals of requirements for a software change. It provides clear, version-controlled documentation of behavioral changes to maintain alignment across the software development lifecycle.

You document software requirements by defining both happy path and edge case scenarios for each requirement using Given/When/Then formatting. This structure ensures requirements are clear and testable for developers and testers.

To write a delta spec for a new feature, generate structured specifications detailing the added, modified, and removed requirements. Include corresponding testable scenarios and apply RFC 2119 keywords to indicate requirement levels precisely.

You need to use RFC 2119 keywords when writing delta specifications to clearly define the obligation levels of requirements, such as MUST or SHOULD. This ensures behavioral changes are documented with unambiguous clarity for implementation.

Yes, generating delta specifications supports version-controlled documentation by explicitly detailing added, modified, and removed requirements. This structured approach tracks behavioral changes clearly across software development lifecycles.

The best way to outline modified and removed requirements is generating a delta specification that structures these changes alongside their corresponding scenarios. Applying Given/When/Then formatting ensures the documented behavioral changes remain testable.
