Building a web application begins by outlining user roles, primary scenarios, and the data structure. A robust MVP concentrates on essential flows, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a brittle collection of ad-hoc screens.

Post-launch, the focus shifts to scalability and dependability: performance budgets, caching strategies, strong authentication, and well-defined API contracts. With effective monitoring, continuous integration/continuous deployment, and careful architecture, teams can iterate more quickly while preserving codebase stability as features and demand expand.
