Reducing Risk in Conformance Decisions (EMU 401)

This two-day course provides the information needed to evaluate the decision risk for measurements used in conformity assessments, and to develop decision rules that mitigate the risks based on international Standards and internationally accepted practices such as ANSI Z540.3 and ISO/IEC 17025.  


Course Content

Metrology and the Consequences of Bad Measurement Decisions.

  • The basics of metrology, measurements and risk.
  • The essential elements for “good” measurement decisions including factual case studies.
  • When more than one element fails. 

Evaluating Measurement Data to Reduce Decision Risk

  • Introduction & Concepts:
    • Measurements, uncertainty, and risk;
    • Why bad measurement-based decisions happen;
    • Visualizing measurement decision risk; and
    • History, evolution, and background to reducing measurement decision risk.
  • The basics of measurement decision risk analysis:
    • Basic probability concepts;
    • Consumer and producer risk; and
    • The quality of a measurement system.
  • Computing risks:
    • Influences on the general risk model (with differences between JCGM 106 & Z540.3);
    • Specific risk functions;
    • Global risk – Consumer risk; and
    • Global risk – Producer risk.
  • Methods for achieving acceptable risk levels:
    • Using the risk models;
    • Specific risk;
    • Global risk;
    • Achieving acceptable risk levels within the Quality Management System; and
    • Summary.
