Define a complete first version
Start with one user outcome and a small set of acceptance criteria. Keep optional features in a later list so the core path can be finished, tested, and explained.
- Name the user outcome
- Define valid input
- Define visible output
- List failure cases
Choose a simple architecture
Separate interface code, domain rules, and storage or network boundaries. This creates testable functions and makes future changes easier to localize.
- Input boundary
- Validation and business rules
- Persistent or remote data
- Rendered result
Build in verifiable milestones
Complete one thin vertical slice at a time. After each slice, run the feature, add a focused test, and write a short note about the decision you made.
- Happy path
- Invalid input
- Persistence or API failure
- README and demo
