My MVP Works But Keeps Breaking: What to Fix First

If your MVP works but keeps breaking, the priority is to make core user journeys reliable before expanding feature scope.

What the Problem Looks Like in Practice

Teams usually see:

• frequent regressions on core workflows
• release fear and slower decision making
• repeated hotfixes that increase technical debt
• roadmap slips due to quality firefighting

Why It Happens

An MVP is built for learning speed. Once demand grows, the same shortcuts become instability multipliers unless delivery controls evolve.

How to Fix It Step by Step

1. identify and protect revenue-critical flows first
2. enforce CI/CD gates before production merges
3. add monitoring around errors, latency, and failed actions
4. isolate high-change logic behind clear boundaries

For a structured transition path, use Vibe Code to Production and benchmark current state with the Tech Maturity Assessment.

Common Mistakes to Avoid

• rewriting everything before understanding failure patterns
• shipping major refactors without rollback plans
• treating every incident as isolated instead of systemic

Summary and Next Action

An unstable MVP is usually a systems problem, not a single bug problem. Stabilise critical journeys, then scale with confidence.
