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.
