According to the PMBOKGuide, the Cost of Quality (COQ) is divided into two primary categories: the Cost of Conformance and the Cost of Nonconformance.
* Cost of Conformance: This is the money spent during the project to avoid failures. it is considered a " proactive " investment in quality. It is further subdivided into:
* Prevention Costs: Money spent to build a quality product. This includes training the team, documenting processes, equipment for production, and time to do it right.
* Appraisal Costs: Money spent to assess the quality of the product. This includes inspections, destructive testing loss, and laboratory testing.
* Cost of Nonconformance: This is the money spent during and after the project because of failures. This includes internal failures (rework, scrap) and external failures (warranty work, liabilities, lost business).
In option C, training and documenting processes represent prevention costs, while inspections represent appraisal costs. Together, these form the total Cost of Conformance.
Comparison with Other Options:
* A. training, testing, and warranty work: While training and testing are conformance costs, warranty work is an external failure cost (Nonconformance).
* B. equipment, rework, and scrap: While equipment can be a conformance cost, rework and scrap are internal failure costs (Nonconformance).
* D. inspections, rework, and warranty work: While inspections are conformance costs (appraisal), rework and warranty work are both nonconformance costs.
