What is Zero Defect?

Zero Defect is the strategy of systematic defect avoidance in development and production. 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 prevention, Poka-Yoke and data-driven process control loops. 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: IATF 16949:2016 in combination with ISO 9001:2015 (defect prevention and continuous improvement).
  • Typical thresholds (in practice): Target state of zero customer defects; operational KPIs often managed via PPM targets and complaint rates (e.g. below 10 ppm).
  • Validity: “Zero defect” is a strategic target state; operational control uses realistic intermediate goals.

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.
