Starting with user roles, key scenarios, and the data model lays the foundation for the project. A solid MVP concentrates on essential flows, intuitive navigation, and predictable UI components, enabling a quick release without becoming a fragile collection of one-off screens.

After launch, scalability and reliability become paramount: performance budgets, caching, secure authentication, and clean API contracts. With proper monitoring, CI/CD, and well-thought-out architecture, teams can iterate faster while keeping the codebase stable as features and traffic grow.
