Developing a web application begins by outlining user roles, essential scenarios, and the data model. A strong MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, enabling a fast release without becoming a brittle collection of ad-hoc screens.

Post-launch, scalability and reliability are paramount: performance budgets, caching, robust authentication, and clear API contracts. With effective monitoring, CI/CD, and well-considered architecture, teams can iterate more rapidly while preserving codebase stability as features and traffic increase.
