Building a web application begins by outlining user roles, essential scenarios, and the data model. A strong MVP concentrates on main flows, intuitive navigation, and reliable UI components, enabling rapid delivery without becoming a fragile collection of ad-hoc screens.

Post-launch, scale and dependability take precedence: performance budgets, caching strategies, secure authentication, and clear API contracts. With effective monitoring, CI/CD, and well-considered architecture, teams can iterate more quickly while preserving codebase stability as features and traffic expand.
