Answer four questions
Whether core value works without it, user demand evidence, build vs. stub effort, and whether a manual workaround exists.
INTEGRATION SCOPE CHECK
Integration Necessity Test
Test whether a planned integration is truly required for your MVP, or whether it should be stubbed or deferred.
- Uses your inputs in a transparent calculation
- Instant result with practical next steps

Frequently asked questions
What does 'stub it' mean?
Build a lightweight fake version — a hardcoded response, a manual process behind the scenes, or a minimal version — so you can validate demand before investing in the full integration.
Why does a manual workaround matter?
If you or the user can do the same thing manually for now, that's evidence the integration isn't blocking core value delivery yet.
What if demand is strong but building is hard?
The test weighs demand and effort together — strong demand plus a workaround gap still pushes toward building or stubbing sooner rather than later.
Can I re-run this as my MVP evolves?
Yes — re-run it whenever demand evidence or your effort estimate changes; the verdict is meant to shift with new information.
Is this only for third-party API integrations?
No — it works for any integration decision, including internal tooling, notifications, or payment providers.
