Turn agreement into observable expectations
A Rule should express a condition that matters to the outcome. It gives the customer and delivery team a shared basis for design, review, and acceptance.
- Connect it to the Goal
- Make the expected behavior understandable
- Identify the relevant boundary or risk
- State how the condition can be evaluated
Use concrete language
Words such as secure, scalable, intuitive, and fast need enough context to be useful. The public principle is simple: important expectations should be reviewable rather than left as slogans.
