How I work
What is not specified cannot be tested. What is not tested cannot be trusted.
The V-model. Every step on the left has its test on the right. Pick a level.
Build
Every requirement gets the test that proves it.
- MeasurableAn automation has to prove its savings. Measure first, then claim.
- AdaptableThe software adapts to the real workflow, not the other way round.
