Web application development begins by outlining user roles, major use cases, and the data structure. A well-defined MVP concentrates on essential paths, intuitive navigation, and stable UI elements, enabling fast delivery without becoming a brittle collection of ad-hoc screens.

Post-launch, scalability and dependability are paramount: performance budgets, caching, robust authentication, and tidy API agreements. With effective monitoring, CI/CD, and deliberate architecture, teams can iterate more quickly while preserving codebase stability as features and traffic increase.
