Creating a web application begins by outlining user roles, essential scenarios, and the data model. A robust MVP concentrates on the main flows, intuitive navigation, and consistent UI elements, so the product can ship quickly without degenerating into a fragile collection of ad-hoc screens.

Post-launch, performance and reliability are paramount: performance budgets, caching, secure sign-in, and clean API definitions. With effective monitoring, continuous integration and deployment, and thoughtful system design, teams can iterate more rapidly while keeping the codebase stable as features and traffic expand.
