Web application development begins by outlining user roles, primary scenarios, and the data model. An effective MVP concentrates on essential flows, intuitive navigation, and consistent UI components, enabling the product to launch promptly without becoming a brittle collection of ad-hoc screens.

Post-launch, scalability and reliability are paramount: performance budgets, caching, secure authentication, and clean API interfaces. With proper monitoring, CI/CD, and thoughtful system design, teams can iterate more rapidly while keeping the codebase stable as features and traffic expand.
