Change Card template: the smallest spec engineers trust
PRDs are too big. Tickets are too small. Use a Change Card to define the reviewed handoff engineers can trust.
PRDs are too big. Tickets are too small.
The missing unit is a Change Card.
A Change Card is not more documentation. It is the smallest reviewed handoff engineers can trust before the work reaches the tracker.
Why engineers do not trust vague specs
Engineers get blamed for:
- scope creep
- hidden blast radius
- broken flows
- auth or PII surprises
- changes that looked safe until they were live
So the handoff has to answer:
- what is changing?
- what does done mean?
- what surfaces does this touch?
- how do we verify it?
- how do we roll it out safely?
Change Card template
INTENT (1 sentence): WHAT changes: WHY now (evidence links): ACCEPTANCE CRITERIA (measurable): SURFACES TOUCHED: UI / API / DB / Policy / Docs RISKS: auth / PII / migration / backwards compat VERIFY: tests + runtime signal ROLLOUT: flag? staged? thresholds? OWNER:
Why it matters
A Change Card turns messy signal into a handoff that survives review.
That is the point.
Without it, teams export vague intent and ask engineering to recover the missing truth downstream.
Where ContractSpec fits
ContractSpec turns messy source material into Change Cards, then keeps the Impact Report and Checks attached to the same operational trail.
