Starting with defining user roles, key use cases, and the data model sets the foundation for a web app. An effective MVP prioritizes essential flows, intuitive navigation, and consistent UI components, enabling rapid delivery without turning into a patchwork of ad-hoc screens.

After launch, performance, reliability, and scalability become the top priorities: budget-driven performance, caching strategies, secure login, and clean API contracts. With proper observability, CI/CD pipelines, and thoughtful architecture, teams can iterate more quickly while keeping the codebase stable as features and traffic expand.
