Decision Rules in Metrology: Managing Risk in Conformity Assessment
| 20 – 24 Apr. 2026, Abu Dhabi | 17 – 21 Aug. 2026, Dubai |
COURSE OVERVIEW:
The meaning of this course lies in the critical logic of determining whether a product "passes" or "fails" when measurement results are close to a specification limit. Metrology is not just about measuring; it is about making informed decisions under conditions of uncertainty. This course provides the mathematical and philosophical framework required by ISO 17025 to manage the "Shared Risk" between the laboratory and the customer during conformity assessments.
The scope of the training focuses on the interaction between measurement uncertainty and tolerance limits. It addresses the various "Decision Rules" such as Binary and Non-Binary statements and the application of "Guard Bands" to reduce the probability of false acceptance (Consumer's Risk) or false rejection (Producer's Risk). Participants will explore how to quantify the "Global Risk" and communicate these complex metrological decisions in a clear, legally defensible manner.
The coverage includes a detailed investigation into ILAC–G8 guidelines, the calculation of "Probability of Conformity" and the statistical modeling of risk using various distribution types. The course also emphasizes the contractual importance of agreeing upon decision rules with stakeholders before testing begins. By mastering these decision-making methodologies, laboratory managers can minimize the financial and safety risks associated with incorrect conformity statements in highly regulated industries.
COURSE OBJECTIVES:
After completion of this course, the participants will be able to:
- Apply the requirements of ISO 17025 regarding Decision Rules.
- Differentiating between False Acceptance and False Rejection risks.
- Calculate the "Guard Band" based on measurement uncertainty.
- Implement the ILAC-G8 guidelines for conformity assessment.
- Quantify the Probability of Conformity for a given measurement.
- Formulate clear and compliant "Statements of Conformity" in reports.
- Manage "Shared Risk" agreements with customers and stakeholders.
- Utilize statistical distributions to model risk in metrology.
- Evaluate the impact of "Measurement Capability" on decision risk.
- Minimize the "Consumer's Risk" in safety-critical industries.
- Design decision rules that align with organizational risk appetite.
- Communicate the logic of metrological decisions to non-experts.
TARGET AUDIENCE:
This course is intended for Metrologists, Laboratory Managers, Quality Assurance Specialists, Technical Auditors, and Regulatory Affairs Professionals.
TRAINING COURSE METHODOLOGY:
A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximize the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.
The course participants shall be evaluated before, during, and at the end of the course.
COURSE CERTIFICATE:
National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
