Excel formula for Cp, Cpk, Pp, and Ppk. Technician's Assistant: When did you last update Excel? Its current, i have office 365. Technician's Assistant: Anything else you want the Software Expert to know before I connect you? I've searched the internet for hours to find a simple formula sheet for statistical calculations with no luck, i'm about to burst

Formula of Ppk (Process Performance Index): Ppk = Minimum of PPU or PPL PPU= ((USL-Average of average)/ (3 X S)) PPL= ((Average of average-LSL)/ (3 X S)) Formula of Ppk (Process Performance Index): Ppk = Minimum of PPU or PPL PPU= ((USL-Average of average)/ (3 X S)) PPL= ((Average of average-LSL)/ (3 X S)) I can't comment on PPK specifically, but to your question about the MIN formula, the comma separates the two values you want compare. So you are comparing USL-mean/3* to mean-LSL/3* Ppk = Min (PpU, PpL) PpU = NORMSINV (WEIBULL (USL, Shape, Scale, TRUE)) PpL = NORMSINV (WEIBULL (LSL, Shape, Scale, TRUE)) If there is only a USL or LSL, the Weibull histogram Ppk is either PpU or PpL. Learn How to Calculate Pp & Ppk - Tutorial, Definition and Example Process Performance (Pp) Definition: Process Performance denotes whether a process is performing correctly in a certain period of time within the overall requirement. Pp and Ppk Process Performance Metrics; Pp: How well the data would fit within the spec limits (USL, LSL) Ppk: How centered the data is between the spec limits. Use Pp Ppk: When you have the total population and are testing the performance of a system to meet customer needs. Pp Ppk: Formulas use standard deviation. Ppk can be determined by diving the Z score by three.
