Data we collect describe the past. Their analysis tells us also about the past. A key question during Process Capability Analysis is: how can we use data collected in the past to describe future? How can we estimate risk associated with the fact that our predictions will not become true in the future? It is normal that customers want to know if a supplier is able to deliver components according to their specification. Aside from the supplier’s promises, the customer usually needs evidence which confirms the supplier’s assurances. What kind of evidence can the supplier offer? How can it be proved that the process is suitable for the manufacturing of components and will fulfill quality requirements? One way is estimation of Capability Indexes.

Without prior agreement on how to collect data, it is very easy to manipulate values to make them look good. This is why we need a way to describe processes in reliable way, to be fair for both supplier and customer. The training we offer will show you how to describe processes in a fair and practical way.

Training Plan


Introduction to variation (basic definitions and statistics)lecture
Quincounx: practical exercise that shows why it is so critical to distinguish between common cause and special cause variationpractical exercise
Introduction to sampling ? two-level Sampling Trees, data analysis: Practical (Box Plot) and Graphical way (Control Charts)lecture


Capability Study: Indexes Cp, Cpk, Cm, Cmk, Pp, Ppk: calculation, interpretation, and limitation of conclusions, e.g. how the way of data collection can influence values of capability ratioslecture
Hands-on and case studies, during which participants discover next limitations of calculated indexes and in the same moment learn how to calculate and interpret results of our process and take the right decisions in the right moment base on fully reliable datapractical exercise + case study
