Review a change across the blueprint
Product requirements evolve. A seemingly small feature can affect data storage, API behavior, permissions, user flows, tests, and delivery work. Impact analysis helps identify those relationships before an update is applied, reducing the chance that one planning document changes while related documents are forgotten.
Example change flow
STEP 01
Request a requirement change
Ask to add profile-picture uploads to the product requirements, including who can upload and replace an image.
STEP 02
Inspect related concerns
Review proposed effects on storage, a profile data field, upload validation, authorization, and an API operation.
STEP 03
Apply a coherent update
Confirm the change, then inspect the updated requirements, data model, API contract, and relevant delivery tasks together.
Human review remains part of the process
Impact analysis is a planning aid, not a guarantee that every implementation consequence has been discovered. Review security, privacy, migration, failure handling, and provider-specific behavior with the people responsible for the system. Keep unresolved questions visible in the documents.
Preserve the result
A versioned blueprint makes a change understandable after the discussion is over: the team can see the request, affected artifacts, and resulting state. When the review is complete, follow the Markdown export guide to place the documents beside the code.
