First Application
Begin with one bounded user outcome that exercises the application structure without introducing unnecessary scope.
Build the First Slice
1. Define the intended user, action, outcome, and authorization boundary. 2. Create a focused microservicelet and a readable route for the experience. 3. Load and validate request data in the route controller. 4. Put reusable rules and persistence operations in a feature-scoped application class. 5. Render the experience in its pagepart using established theme and interface patterns. 6. Add only the route-specific styles or browser behavior the workflow requires. 7. Document the user task, permission expectations, expected result, and safe recovery path.
Verify the Outcome
Test anonymous and authenticated access as applicable, permitted and denied roles, valid and invalid input, empty and populated states, keyboard operation, responsive layout, and the resulting data or evidence. Confirm that errors do not reveal implementation details.
Once this vertical slice is reliable, extend the application through similarly bounded features rather than growing one route into an entire system.
