Web application development begins by outlining user roles, key use cases, and the data model. An effective MVP prioritizes essential flows, intuitive navigation, and consistent UI components, enabling the product to launch swiftly without becoming a fragile collection of ad-hoc screens.

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