POOR-QUALITY COST CONCEPT AND PRACTICE Evolution Of H. J. Harrington's Poor-Quality Cost Model In the 1950s, A. V. Feigenbaum, then VP at General Electric (GE), developed and implemented the "Cost of Quality" concept throughout GE. He divided Cost Of Quality into the following two categories and four sub categories:
Feigenbaum's concept was later adopted by several large American firms. In the 1960s, Dr. James Harrington was assigned to implement Dr. Feigenbaum's Cost Of Quality concept at IBM. He found the concept lacking because it did not focus on the support functions' cost of quality or the external customers' quality costs. As a result, IBM expanded the concept to fulfill its own needs. To distinguish it from Feigenbaum's concept, IBM used the name "Poor-Quality Cost." This name was selected because IBM felt that Cost Of Quality was an inappropriate title: Good quality does not cost any additional money. It is poor quality that generates the additional costs for the company. If we had perfect quality, we would not have a need for preventive cost or appraisal cost, and there would be no internal error cost or external error cost. Unfortunately, we do not live in a perfect world. In January 1964, IBM published its first report that included poor-quality cost for internal component manufacturing, subassembly, final assembly, final machine test, system test, and the first 12 months at the customer location for the 1620 system. It was called the Q-100 Report. During the following months, this report was expanded to cover many other IBM systems. A number of technical reports and articles were published during the 1970s documenting IBM's approach to Poor-Quality Cost. IBM's Poor-Quality Cost system included the following elements: |

Table 1: The Elements of Poor-Quality Cost In the early 1980s, Philip Crosby left ITT where he had earlier also implemented Feigenbaum's Cost Of Quality concept and incorporated the concept into his own consulting practice. Crosby's approach closely followed Feigenbaum's teachings, although he changed the names of some of Feigenbaum's terms without altering their meaning. In 1987, the American Society for Quality Control (ASQC) published Dr. Harrington's book entitled, Poor-Quality Cost, which documented IBM's approach to reporting the costs that result from poor quality. This book has since been translated into many languages, including Chinese, French, Spanish, Portuguese, and Russian. In the early 1980s, while developing the Business Process Improvement methodology that focused on streamlining business processes, Dr. Harrington found that the costs that resulted from poorly-designed business processes were also poor-quality cost elements. As a result, he included "no-real-value-added" elements to his Poor-Quality Cost model in 1990. In 1994, after doing extensive work with sales and marketing functions, Dr. Harrington began to realize that the concept of lost-opportunity cost also had a major impact on the corporate bottom-line. As a result, lost-opportunity cost was added as a new element. Table 2 reflects Dr. Harrington's most recent Poor-Quality Cost model. |

Table 2: 1994 Poor-Quality Cost Model The importance of including some of these new PQC elements in Dr. Harrington's model has been verified in many organizations over the past year. When Saab's R&D organization looked at its Poor-Quality Costs, it was amazed to find that 78 percent of its R&D budget was classified as Poor-Quality Cost. Likewise, in a marketing and sales organization, the Poor-Quality Cost is often more than 100% of the marketing and sales budget when lost-opportunity costs are considered. I am in the process of writing a new book for McGraw-Hill entitled "Measuring Poor-Quality Cost" (Table of Contents is attached.) I would like to acquire case studies, examples, and quotes that can be used in this book.
