How to manage quality costs?

It is much less costly to prevent a problem from ever happening than it is to find and correct the problem after it has occurred. Prevention costs support activities whose purpose is to reduce the number of defects.
Why do companies provide technical support to their suppliers?
Some companies provide technical support to their suppliers as a way of preventing defects. Particularly in just in time (JIT) systems, such support to suppliers is vital. In a JIT system, parts are delivered from suppliers just in time and in just the correct quantity to fill customer orders. There are no stockpiles of parts. If a defective part is received from a supplier, the part cannot be used and the order for the ultimate customer cannot be filled in time. Hence every part received from suppliers must be free from defects. Consequently, companies that use just in time (JIT) often require that their supplier use sophisticated quality control programs such as statistical process control and that their suppliers certify that they will deliver parts and materials that are free of defects.

Overview
- In process improvement efforts, quality costs or cost of quality is a means to quantify the total cost of quality-related efforts and deficiencies. It was first described by Armand V. Feigenbaum in a 1956 Harvard Business Review article. Prior to its introduction, the general perception was that higher quality requires higher costs, either by buying better materials or machines or by hiring m…
Cost
- The fundamental principle of the cost of quality is that any cost that would not have been expended if quality were perfect is a cost of quality. This includes such obvious costs as scrap and rework, but it also includes many cost of quality categories that are far less obvious, such as the cost of reordering to replace defective material. Service businesses also incur quality costs; …
Prevention
- Prevention costs are costs of all activities that are designed to prevent poor quality from arising in products or services. Examples include the costs for:
- For most organizations, quality costs are hidden costs. Unless specific quality cost identification efforts have been undertaken, few accounting systems include provision for identifying quality costs. Because of this, unmeasured quality costs tend to increase. Poor quality impacts companies in two ways: higher cost and lower customer satisfaction. The lower satisfaction cre…
Results
- As Figure 3 shows, business processes with better process sigma will have significantly lower prevention and appraisal costs. Although you will never fully eliminate appraisal and prevention costs (as opposed to failure costs that in an ideal zero defect world would also be zero), their reduction due to better process performance will be significant.
Definition
- As defined by Philip B. Crosby in his book Quality Is Free, the cost of quality has two main components: the cost of good quality (or the cost of conformance) and the cost of poor quality (or the cost of non-conformance). As Figure 1 shows:
Example
- What is the relation between the cost of good quality and the cost of poor quality? The traditional view would be to conclude that if a company wants to reduce defects and by this reduce the cost of poor quality, the cost of good quality would have to be increased, meaning higher investments in any kind of checking, testing, evaluation, training of operators, etc. Following the Six Sigma ph…
Reporting
- To ensure impartiality, reporting should be performed by the accounting department. Additionally, to make it more understandable to a wider audience, the total cost of quality should be reported as a percent of sales, cost of sales, cost of manufacturing, or for firms in the service industry, cost of operations.
