The value of quality improvements

Abstract

Purpose -To present a proactive quality costs measurement methodology, which describes the value of quality improvements and the implication of this value on customers' perception regarding the value of the product. Design/methodology/approach -By describing the perceived customer value in a dynamic term, it becomes possible to derive an analytical model that recognizes the implication of a company's efforts to improve design quality and conformance quality on product value as perceived by the customers. Quality costs as a performance indicator of improved design quality and conformance quality (as the results of prevention and appraisal activities) can be expressed in terms of value (i.e. a trade-off between benefits and sacrifices), where the benefits of the improvement include higher product quality and reduction of failure costs. The sacrifices include the costs to perform improvement activities (i.e. prevention and appraisal costs). Expressing quality costs in this way thus establishes a link between producer's efforts to improve quality and the way customers perceive the value of the product. The developed methodology of proactive quality cost measurement has been applied for collecting, measuring, and reporting quality costs in a Swedish wood-flooring manufacturing company. Findings -Transforming quality cost measurements into value provides a better explanation regarding the effect of prevention and appraisal activities on the quality improvement indicators. Thus, the value of quality improvements is a measure of return on quality improvements (ROQI), which indicates whether the quality improvement efforts gave higher, fair, or lower return. Originality/value -This paper develops and discusses a model of customer value by accommodating its relative-nature, and presents a proactive way of measuring quality costs (i.e. value-oriented and customer-oriented).

A case study on FMEA-based quality improvement of packaging designs in the TFT-LCD industry

“…The TQM approach, which is usually conducted in combination with FMEA and the fault tree analysis to resolve issues, has more prominent effects as compared to FMEA (Devadasan, Muthu, Samson, & Sankaran, 2003;Elmquist & Tehrani, 2008). Setijono and Dahlgaard (2008) suggested that from the standpoint of quality and cost, it can better assist enterprises in increasing the quality level, improving the overall profit, and reducing the risk of failures and eventually turns them into more valuable enterprises. Rodchua (2006) indicated that that it is difficult for enterprises to reduce the quality cost if they could not discover problems through the process of quality improvement.…”

The Quality Costs Assessment in the Aspect of Value Added Chain

“…In this stage the influence of quality costs to added value is also calculated. For that purpose, Setijono and Dahlgaard (2008) two-dimentional vector of influence is also calculated. First part of vector's equation .…”

Research of Solidity and Reliability of Mass Customized Products in Competitive Manufacturing System

“…Part of tests, accomplished at the Technological Experiments Centre during the period 2008-04-01 -2011-01-01 is presented in Table. The data of only weakest parts of bicycle, where the risk of breaking is the highest according to test results are presented in this Table. Parts of bicycles, which didn't break during the tests detected that these parts are substantial, reliable and quality is quite enough. Total quality of the assembled bicycle depends on reliability and quality of all parts of bicycle [9]. As shown in the Table, the weakest parts of tested bicycles are brakes, carriers and front fork.…”
