Product development for web apps begins by outlining user roles, primary use cases, and the data model. An effective MVP emphasizes essential flows, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a brittle collection of ad-hoc screens.

Once deployed, scalability and reliability become the priority: performance budgets, caching, secure login, and well-defined API contracts. With proper monitoring, CI/CD practices, and thoughtful architecture, teams can iterate more quickly while keeping the codebase stable as features and traffic expand.
