Building a web app begins by outlining user roles, essential use cases, and the data structure. A strong MVP emphasizes core workflows, intuitive navigation, and consistent UI elements, enabling rapid release without becoming a brittle collection of piecemeal screens.

Post-launch, the focus shifts to scalability and dependability: performance ceilings, caching, robust authentication, and clean API definitions. With effective monitoring, CI/CD, and well-planned architecture, squads can iterate more quickly while sustaining codebase stability as features and traffic expand.
