Cost of Conformance
Cost of conformance is the money spent during the project to avoid failures, including prevention costs (building a quality product) and appraisal costs (assessing the quality).
Explanation
Cost of conformance represents the proactive investment in quality. It encompasses two subcategories: prevention costs and appraisal costs. Prevention costs are incurred to keep defects from occurring, such as training, equipment calibration, process documentation, design reviews, and time spent doing work correctly. Appraisal costs are incurred to evaluate whether deliverables meet quality standards, such as testing, inspection, destructive testing, and quality audits.\n\nThink of conformance costs as "the cost of doing it right." These are voluntary investments the project team makes to ensure quality. While they add to the project budget, they typically save money overall by reducing the much higher costs of rework, warranty repairs, and customer dissatisfaction.\n\nIn practice, increasing prevention spending is the most effective way to reduce total cost of quality. Well-trained teams using well-documented processes with proper equipment produce fewer defects, which reduces both appraisal needs and failure costs. This is why PMI emphasizes that quality must be planned in, not inspected in.
Key Points
- •Includes prevention costs and appraisal costs
- •Prevention costs: training, documentation, equipment, design reviews
- •Appraisal costs: testing, inspection, audits, destructive testing
- •Represents voluntary investment in quality to avoid failures
Exam Tip
If the exam gives you a cost and asks whether it is conformance or nonconformance, ask yourself: was this money spent to prevent or detect defects (conformance), or because a defect occurred (nonconformance)?
Frequently Asked Questions
Related Topics
Cost of Quality (COQ)
Cost of Quality (COQ) is the total cost incurred over the life of a product by investing in preventing nonconformance, appraising deliverables for conformance, and dealing with failure when requirements are not met.
Cost of Nonconformance
Cost of nonconformance is the money spent during and after the project because of failures, including internal failure costs (defects found by the project) and external failure costs (defects found by the customer).
Prevention vs Inspection
Prevention keeps errors out of the process by designing quality into the work, while inspection keeps errors out of the hands of the customer by examining deliverables after they are produced.
Quality Audits
A quality audit is a structured, independent review to determine whether project activities comply with organizational and project policies, processes, and procedures.
