Process capability consulting
Stable. Reproducible. Mastered.
A good test report is worthless if the process behind it is not stable. That’s why, in addition to measurement technology and data analysis, we also offer targeted advice on process capability – with a focus on the technical feasibility, repeatability and validation of your production processes.
We support you from the initial capability analysis (e.g. as part of an EMPB) through the derivation of optimization measures to audit compliance in the series production process.
What we do
We analyze your components, test data and process conditions with the aim of making process capability measurable and ensuring it. Among other things, we consider
- Measured values from EMPBs and series tests
- Production parameters and their influence on characteristic scatter
- Cmk / Cpk / Ppk values in the context of real tolerances
- Testing and tolerance strategies, tailored to component function
- Boundary features & critical features (KMs)
- Effects of material and tool deviations
- Integration into CAQ or QA systems
Typical scenarios
- Proof of capability before series release (e.g. PPAP, VDA 2)
- Evaluation of process stability after tool correction
- Derivation of realistically realizable tolerance specifications for new components
- Support with audit preparation (customer, OEM or IATF audits)
- Securing corrective measures following complaints or delays
Your advantages
- Practice-oriented - with real reference to components, tools and testing
- Quickly assessable through graphical and statistical key figures
- Can be ideally combined with scan and EMPB data
- Targeted - no abstract advice, but real production proximity
Do you regularly have components within the drawing but outside the process?
We help you to understand exactly that – and fix it.
