What are Quality Costs?
Quality costs or Cost of Quality (COQ) are the costs associated with the Quality related efforts by Organizational personnel. Every Organization puts a certain level of effort in maintaining the Quality level that it claims for its products and services or that meet the expectations of its Customers. These costs are called Quality Costs.
An American Quality Control expert called Armand V. Feigenbaum first introduced this concept of cost of Quality in the year 1956 in a Business Management article.
Till this concept was introduced, Financial personnel did not think that there can be costs associated in maintaining the Quality level in an Organization. It was an eye opener to understand that "Quality also costs".
