What kind of change is this?
The category drives everything downstream. Different change types propagate to different systems — a "combo" usually means scope each independently.
Pick all the lenses that fit. A rate change with a new UI is two lenses; a back-end integration with no premium impact is one.
Who is impacted?
For policy-product changes, the most common cause of missed requirements is solving for one stage — usually new business — and forgetting the others exist. For UI / integration / reporting changes, "applicability" may collapse down to "everyone the moment we deploy."
Default assumption is "all three" until proven otherwise.
Quote date, bind date, and policy effective date are three different things. Pick one and document it.
If renewal effective is May 1 and you require 60 days' notice, the change must be locked in by March 1.
Notice and consent requirements vary by state and change type. Claims occurring before the endorsement date are evaluated under the OLD coverage.
Existing business — old rules or new?
Grandfathering is never a default. It is always an explicit business decision that must be documented, and it has system impact.
Who interacts with the change?
D2C and the agent portal have separate lifecycles and separate failure modes. Each must be scoped explicitly.
D2C — self-service has no agent safety net
Rule of thumb: if a change requires an agent to explain it, D2C will expose it.
Agent Portal — the things BAs forget to scope
Core systems & downstream
Default assumption: any change in PC has at least one BC impact to investigate. Prove the negative if you're claiming "no BC impact."
Downstream & reporting
If your change touches money, coverage, or eligibility — assume at least three of these are affected until proven otherwise.
Edge cases & sign-off
These are the questions that catch missed requirements. Walk through each with the PO.
