Improving the definition and quantification of quality costs - Oxfordshire, UK : Taylor & Francis, March-April 2008

A difficulty facing companies today is the inadequacy of most cost-accounting systems in addressing quality costs and in supplying appropriate data in a suitable format that considers total cost. The main reason for this inadequacy is a lack of adequate methods for determining the financial consequences of poor quality associated with various quality activities. The present study addresses these needs by first refining the traditional 'Prevention-Appraisal-Failure' (PAF) categories of quality costs and hidden costs through the definition and addition of two new categories: 'extra resultant cost' and 'estimated hidden cost'. Using this new categorization, the study then provides a detailed classification of the items of quality costs in terms of an expanded list of quality activities along the product life-cycle. The study then demonstrates the calculation of several kinds of total costs using different formats of a 'cost of quality account matrix', including a calculation of the sharing of responsibility for these costs among relevant departments
