Design Backward

  • • Every model starts from one measurable money metric
  • • Offline accuracy is evidence, not the objective
  • • Sponsors agree on the outcome before modeling begins

Stop Conditions

  • • Independent validation can send a model back to modeling
  • • Sign-off is a human gate, not a formality
  • • Drift in production reopens the rework loop

Value Survives Launch

  • • Serving and feature parity are part of the model, not an afterthought
  • • Shadow running proves behavior before real money moves
  • • Monitoring tracks business value, not just latency
