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

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