Process capability analysis: Basics and practical applications

Background, introduction
Process capability is a process for determining appropriate metrics to describe how well a process delivers what the customer wants. The best-known indicators are the process capability indices cP and cPK, which are defined in relevant standards. Both values indicate how reliably a process achieves the given goals and specifications.

Benefits and objectives
The benefits of the training for the participants is learning about the process capability index and evaluating it. Participants learn how to calculate these indices with a user-friendly software (Minitab®) and – very importantly – learn which conclusions can be drawn from this for the purpose of process optimization.

The one-day training
The one-day training deals with the common indicators for describing the quality of processes (Cp,CpK, Cm, others). The training not only teaches how to determine the various key figures, but also takes an in-depth look at the evaluation and interpretation of the key figures. It therefore teaches participants how these key figures can be used to improve processes.

The training first of all clarifies processes that follow a normal distribution. On the basis of practical examples, key figures for good and bad processes are determined and evaluated. Processes that do not follow a normal distribution are then explained.

The short and long-term process capabilities are discussed, evaluated and compared.

In addition, process capabilities are also determined and clarified for faulty units too and for the number of faults, using practical examples.
