This ONE DAY course is designed to provide participants with an understanding of the principles of MSA and the methodologies for performance of measurement systems studies.  At the conclusion of the course participants will understand the methodologies of MSA with respect to bias, linearity and stability and will have performed an R&R study.  They will have interpreted the results in the context of the process variation and product acceptance criteria and used the data to improve the effectiveness of the measurement system.

The structure is designed to be highly practical and avoids detailed knowledge or discussion of statistics.

Key Session Topics

  • Concepts of MSA
    • Measurement system elements and their contribution to measurement variation
    • Terminology and concepts (bias, linearity, stability, repeatability and reproducibility)
  • The existence and measurement of variation
    • Variation
    • Normal Distribution
    • Accuracy and Precision
    • Measures of variation (mean, standard deviation and variance)
  • MSA Studies
    • Bias (overview and methodology)
    • linearity (overview and methodology)
    • stability studies (overview and methodology)
    • Measurement Uncertainty (overview)
    • Measurement system analysis and studies (variable and attribute)
    • Repeatability and Reproducibility
    • Performance of a gauge R&R study
  • Interpretation and use of study data (from example data provided)
  • Using data for cost-saving (calibration intervals, number of measurements taken etc)


  • Hands on experience in how to produce an MSA study
  • An understanding of how MSA studies are carried out and used to determine the suitability of measurement systems.

Who should attend

  • People with responsibility for design / process engineering who should be requiring MSA studies to help them specify tolerances, production processes and acceptance criteria, and need to understand the information when it is presented.
  • Those who are required to support MSA studies, but are not directly responsible for the analysis.
  • In house "experts" who need to plan and execute MSA studies and will become the "champions" for the appropriate use of MSA to drive continuous improvement and influence senior management.

Course techniques

Understanding is developed through the use of tutorial sessions and practical interactive workshops, which provide the student with the opportunity to put the skills taught during the course into practice.
