The office·Quality and inspection data·Root cause, with a person

The tool can line up the evidence. The engineer names the cause.

On the call, we would ask

  • How is a recurring defect investigated today, and how long does it take to gather the evidence?
  • What data exists around a defect: results, lots, machines, shifts, maintenance?
  • Who owns the root cause, and how is it recorded?
  • How often does the first cause named turn out to be wrong?
