What interesting ideas regarding cost of quality can be understood from this material? Please explain.

Cost of quality is one of the essential parts of quality and process improvement. cost of quality is a methodology that allows an organization to determine the extent to which project managers can use project resources for activities that prevent poor quality, that appraise the quality of the organization's products or services, and that result from internal and external failures. four factors contribute to the cost of quality: Appraisal costs, Prevention costs, Internal failure costs, and external failure costs. In our organization, all these factors contribute to the cost of quality in the following ways:

Testing products and services (Appraisal costs): The project team thoroughly tests the product before any software product launch. Quality analyst conducts functional white box and user acceptance testing before any launch. Good quality testing can reduce many product defects once launched and improve the cost of quality.

Quality Management and Process Improvement (Prevention costs): Since our organization follows SAFe, process improvement is continuous. During the end of each sprint, the scrum master and the product owner conduct a sprint retrospective where project teams discuss the areas of improvement within their products and the overall process. Therefore, it leads to comprehensive quality management and process improvement.

Bug fixing (Internal failure costs): Bug fixing is an essential part of software development in our organization. However, there may be occasions when the project team must fix more than the estimated initial bugs. Therefore, it may sometimes lead to internal failure costs.

External failure costs (Customer dissatisfaction): Satisfying customers is one of the main goals of launching any product. As the saying goes, the customer is the queen or king. Before releasing any product, we always keep our customers engaged through Sprint demos. Furthermore, once the product goes live, we have regular follow-ups with our customers; this, overall, reduces customer dissatisfaction. However, customer dissatisfaction can have a vast failure cost impact on the overall project.
