Выражение встречается в следующем контексте:
Whatever your production run or Cpk goal, chances are your organization will be busy trying to improve processes that are substantially below your Cpk goal.
Organizations should not get hung up on the goal, but instead just get going on improving process capability. This means making processes very predictable and "centered" around a desired performance goal.

Cpk - это статистический индекс смещенности процесса (process capability)
