What is EMPB?

EMPB (Erstmusterprüfbericht / initial sample inspection report) is the documented conformity evidence for a first sample. In the industrial environment, it is used to manage quality risks systematically and make decisions traceable.

Scientific background

The methodological foundation is based on statistical and process-oriented concepts. Central elements are the feature list, measured values, method declarations and deviation assessment. CT data can supplement these systems with internal component information and thereby increase evidence quality.

Relevant key metrics

Effectiveness of the method against defined KPIs and target values.
Reaction time between deviation detection and stable correction.
Sustainability of measures across multiple production cycles.

Standards and thresholds

Standards: VDA Volume 2 (6th revised edition, 04/2020) as well as AIAG PPAP (PPAP-4, 4th Edition, 2nd Printing, Nov 2009).
Typical thresholds (in practice): Evidence of all drawing features in the EMPB; deviations on safety- or function-critical features = 0 for release.
Validity: Scope and documentation depend on submission level and customer-specific requirement.

Application in industrial practice

Risk reduction during development and series ramp-up.
Standardised decision processes across functions and sites.
Linking quality-related evidence to customer requirements.
