Starting with defining user roles, key scenarios, and the data model sets the foundation for a web app. A robust MVP concentrates on essential flows, intuitive navigation, and consistent UI components, so the product ships swiftly without becoming a fragile collection of ad-hoc screens.

After launch, scalability and reliability take center stage: performance budgets, caching strategies, secure authentication, and clean API contracts. With solid monitoring, CI/CD, and thoughtful architecture, teams can iterate more rapidly while keeping the codebase stable as features and traffic grow.
