How I work
Structure before speed
A model runs as well as the system around it. The plan, the pipeline, and the limits are set before the first run, not after the first mistake.
Evidence-based delivery
A number ships only with its method of measurement.
Honest scope
The title is the dotted box, the actual role is the solid one.
