Process capability

Process capability is a measurable property of a process against the specification, expressed as a process capability index (e.g., Cpk or Cpm). The output of this measurement is usually illustrated by a chronological control sample, a histogram and calculations that predict how many parts will be produced out of specification (OOS). If you want to have a look at the template and you have Excel 2019, 2021 or office 365, just download it. If you need another language in the template (Spanish, French, Italian or whatever) just write me a mail (roland.schnurr@sixsigmablackbelt.de),

You can modify all the cells in the template (format, images, etc.), except the grey cells. These are calculated.
