There are many problems which have caused the cost-of-quality approaches to fail. It is unwise to achieve too much too fast. For example, do not try to apply a quality cost system to every project until it has been applied successfully to one project. Do not try to measure all the costs because it may not be possible. There might be many types of costs which the managers may challenge as not being quality-related. If the costs could be included in the totals like the total cost of quality then it may be considered that the totals are being padded to achieve more dramatic effect.
