Proving inspection process capability according to VDA 5 & ISO 22514-7 – professional inspection process management training
As the old saying goes: “You can only manufacture as accurately as you can measure!” This means that the measurement uncertainty of the measurement and inspection process must be known for each measured value in order to be able to assess the measured value in relation to the specification limits. VDA Volume 5 and ISO 22514-7 describe how to determine measurement uncertainty and this approach also serves as a proof of capability. In addition, VDA 5 explains how inspection process management should function for a holistic approach.
In this VDA 5 training course, we will illustrate both key areas relating to process capability. To a large extent, we use software programs and demonstrate the application of the procedures using practical examples. This training focuses on quality management based on VDA Volume 5. This guideline is applied in manufacturing companies from the automotive industry, among others.

What does inspection process capability mean?
In quality management, there are various standards relating to inspection process management, measurement uncertainty and proof of capability.
Inspection process capability according to VDA Volume 5 means that an inspection process is suitable for achieving an inspection decision under defined conditions. Capability is assessed on the basis of capability indices. These capability indices provide information on whether an inspection process is capable of performing the required test task with sufficient accuracy and repeatability.
In many cases, an inspection process is required to be capable and stable. To meet this requirement, its location and variation must remain constant over time, i.e. there must be no trends or systematic changes.
The ComPro VDA 5 training course teaches you the relevant fundamentals, methods and practical implementation of capability analyses in industrial manufacturing.
How are inspection process capability and measurement uncertainty related?
Inspection process capability means that an inspection process is capable of providing reliable and reproducible results and thus distinguishing between good and bad parts. Normally, this is demonstrated by calculating capability indices. However, measurement uncertainty is becoming increasingly important as it is used as an alternative or supplementary method for demonstrating the capability of an inspection process. But why is this the case?
Measurement uncertainty considers all relevant influence quantities (e.g. repeatability, reproducibility, calibration uncertainty) and enables a quantitative assessment of the risk that a product will be incorrectly assessed as compliant or non-compliant. For this reason, it is part of guidelines such as VDA 5, ISO 14253 and GUM.
Since expanded measurement uncertainty can serve as proof of capability for inspection processes, especially when capability indices are not applicable or meaningful enough, it also plays an important role in the ComPro VDA 5 training course.
