Start with the system, not the screen
Clarify the users, decisions, data, ownership, and measurable outcome before choosing features. This keeps the build focused and makes future change easier.
Make risk visible early
Prototype the difficult workflow, validate assumptions with real examples, and define how errors, permissions, content, and integrations will be handled.
Build a maintainable first release
A useful MVP is not disposable. It should create learning quickly while preserving a clear path for iteration, analytics, support, and scale.
