Before launch verify cross-tenant tests, recovery, backup restore, safe billing state, alerts, runbooks, support, cancellation, retention, accessibility, and critical end-to-end journeys.

How to apply it

Track unresolved risks with owners. Do not launch with known cross-tenant defects, exposed production secrets, unverified payment state, or no recovery path for critical data. After launch monitor activation, errors, support, churn, and cost per active organization.

Worked example

If onboarding abandonment rises, inspect the funnel, interview affected users, ship a focused change, and measure activation plus guardrails.

Common mistakes to avoid

Adding unrelated features before understanding customer friction or treating a few early fans as proof of product-market fit.

Practice task

Implement this concept in the capstone. Add one positive test, one negative or failure-path test, and a short note explaining the trade-off you chose.
