### Z Score and Process Capability Six Sigma Study Guide

Z score and Process Capability are used together to get a view of your process.The Z score or value in process capability calculation is the mean distance from specification limits (USL and LSL) measured in standard deviation units..Z score tells the defects within the system.In other words,Z score tells the number of standard deviation existed between the mean and specification limit.What Is The Difference Between Cp,Cpk and Pp,PPK?Cp and Cpk are called Process Capability.Pp and Ppk are called Process Performance.In both cases we want to try to verify if the process can meetNotes on Relating CP and Cpk1.If Cp == Cpk,then the process is perfectly centered.If perfectly centered,Cp == Cpk.2.Because Cpk accounts for centering (where Cp does notASQ Six Sigma Black Belt Certification Process Capability QuestionsQuestion Data being used in the initial set-up of a process are assumed to have a normal distribution.If the nominal (target) is set at the centeASQ Six Sigma Green Belt Certification Process Capability QuestionsQuestion When calculating the Cp index,what does the standard deviation represent in the formula Cp = (USL LSL) / 6?(A) The tolerance intervalProcess Capability Performance (Pp,Ppk,Cp,Cpk)When to Use Pp,PPK,Cp,and CpkDifferences Between CP PpWhat Can Process Capability and Process Performance Tell Us?Is A Process capable?Is The Process acceptable?A Note on A Process Being Both Capable and AcceptableSix Sigma Process Capability Performance LimitsPp vs CPPpk vs CpkPp,Ppk vs Cp,CpkAdditional Notes For Cp,Cpk,Pp,PpkProcess Capability Performance (PP,PPK,Cp,Cpk) Practice QuestionsThe main difference between Pp and Cp on one side and Ppk and Cpk on the other side is whether we use complete set of data for calculation (Pp and Ppk) where we calculate real performance of the system,or we use sample (pre-production,batch,logical subgroups) where we calculate capability of the process.In equation for Pp and Ppk we use standard deviation based on studied data (whole population),and in equation for cSee more on sixsigmastudyguideA Guide to Process Capability (Cp,Cpk) and Process Difference between Cp,Cpk and Pp,Ppk [Potential] Process Capability Analysis (Cp,Cpk) A process capability study uses data from a sample to PREDICT the ability of a manufacturing process to produce parts conforming to specifications.This prediction enables us to qualify a new manufacturing process as being fit for use in production.Some results are removed in response to a notice of local law requirement.For more information,please see here.Previous123456NextSigma 6 Study Guide-CPK Flashcards QuizletProcess Capability Index.Adjustment of Cp for the effect of non-centered distribution.Tells you what the process is capable of doing in the future,assuming that it remains in a state of statistical control.CPK should be greater than 1.5.

### Capability Study - Six Sigma

Capability Study.The capability study is one of the main tools of Six Sigma.It helps us understand what our process capability is and tells us the probability that the process will produce defects.There are 4 main metrics used to define capability.These are Cp,Cpk,Pp,and Ppk.The two metrics starting with C measure short term capability.Capability Study - Six Sigma TerminologyEither the process variation centering is off,or the dispersion (fatness,or slop in the process) is too wide.A capability study will tell you with two numbers represented by either Cp Cpk,or Pp Ppk whether your process is capable of meeting customer requirements in either the short term or the longer-term.BB Exam Archives Six Sigma Study GuideCp and Cpk are considered short-term potential capability measures for a process.In Six Sigma we want to describe processes quality in terms of sigma.This entry was posted in Measure and tagged ASQ ,BB Exam ,Black Belt ,GB Exam ,Green Belt ,IASSC ,Villanova ,Yellow Belt .
