The Cost of Quality (COQ) framework helps organizations understand how their resources are allocated across different quality-related activities. Here are the key categories within COQ:
* Prevention Costs: These costs are incurred to prevent defects from occurring in the first place. Investing in prevention activities reduces the likelihood of quality issues. Examples include:
* Training programs
* Process improvement initiatives
* Design reviews
* Supplier quality management
* Appraisal Costs: These costs are associated with measuring and monitoring quality. They ensure that products or services conform to specifications. Examples include:
* Quality audits
* Verification of incoming materials
* Supplier evaluations
* Internal Failure Costs: These costs occur when defects are detected before the customer receives the product or service. Investing in reducing internal failures is crucial. Examples include:
* Rework or rectification
* Scrap
* Failure analysis
* External Failure Costs: These costs arise when defects are discovered by customers after they have received the product or service. External failures can damage reputation and lead to customer dissatisfaction. Examples include:
* Repairs and servicing of returned products
* Warranty claims
* Product recalls
To maximize return, organizations should focus on prevention because it directly reduces the occurrence of defects, leading to long-term cost savings. By preventing issues upfront, companies avoid the more expensive internal and external failure costs1.

The first phase in initiating a benchmarking plan is to identify what to benchmark. This involves defining a tightly focused subject of the benchmarking study and choosing an issue critical to the organization's success. Before an organization can achieve the full benefits of benchmarking, its own processes must be clearly understood and under control1.

The correct order to create a new service organization starts with clarifying the service strategy (2), then educating the organization (4) to ensure that everyone understands the strategy and their role in it. Following that, implement new tactics at the front line (1), and finally, evaluate the present level of service quality (3) to assess the effectiveness of the changes.
