Q-QUIZ OCTOBER 2018
2018-10-16 - Basics of process capability - test your knowledge!
Most real processes in practice are no longer normally distributed in long-term analyses. ISO 22514-2 shows how to classify changes in the location and variation of a process. This standard also describes the resulting distribution and calculation methods for Cp and Cpk or Pp and Ppk. To simplify matters, the normal distribution serves as an approach to teach the basics of process capability.
