Decision Rules: Reducing Risk in Conformance Decisions
This course covers measurement's influence throughout a product’s lifecycle (design, manufacturing, testing, certification), where it fits within a Management System (MS). Utilizing measurement data, the participant will be introduced to the technical and mathematical tools required to evaluate the probability of false accept and false reject decision risk for measurements used in conformity assessment decisions. The course will detail how this information can be used to balance the cost of managing the likelihood of occurrence against the cost of negative consequences resulting from an incorrect decision.
Prerequisites
Participants should:
- Be familiar with measurement principles and techniques;
- Have a functional understanding of the principles of measurement uncertainty;
- Have received training in engineering, science, or mathematics; and
- Have a basic understanding of calculus, algebra, and statistics.
EQUIPMENT NEEDED:
The participant will need to bring a laptop computer (PC or MAC) with Microsoft Excel or similar spreadsheet installed. Please note that the tablet and smart phone versions of Excel and other spreadsheets do not have the full functionality of the PC versions and the participant may not be able to utilize all the power of the spreadsheet covered during the training.
Target Attendees
This course is intended for a technical audience in the product development, testing (e.g., forensic, pharmaceutical, medical, product, etc.), calibration, operational services, to include:
- Design, test, operation, and instrumentation engineers;
- Quality engineers;
- Researchers;
- Scientists;
- Metrologists; and
- Senior technicians (e.g., manufacturing, testing, medical, etc.).
Learning Outcomes
After successful completion of the course, the participant will be able to:
1. Identify the non-conformant element(s) in metrology-related failures and where it resides within the management system;
2. Recognize specific and global risk requirements in standards and how their differences may impact implementation costs;
3. List the four basic components of the General Risk Model (GRM) and how each influences the model;
4. Using a spreadsheet, develop a mathematical risk model to construct a decision rule; and
5. Develop a decision rule using techniques that balance the cost of metrology with the desired level of decision risk.
