The Total Quality Cost then is simply the sum of all these cost categories; Prevention, Appraisal, & Failure Costs (Internal & External). It is probably the most used framework in combination with some agile processes like scrum or kanban. This software category can refer to a broad range of applications that help manufacturers ensure quality across all supply chain activities—from design to production to distribution and eventually, service. Cost of quality is one of the most established, effective measures of quantifying and calculating the business value of testing. One reason is because if we have a good design, we can start reusing pieces of code after a while. In Principles of Quality Costs, Campenella presents a case study from Raytheon that describes reductions in the cost of software quality from a whopping seventy percent of the total production cost to twenty to thirty percent.
