Measuring Cost of Quality (C.O.Q) and Quality Improvement (Case study: A Steel Company in I.R.IRAN)

The main purpose of this study is to measure the value of quality improvements in one of the two greatest steelmaking factories in middle east during the six months period since June to December,2020 and has used a new method (introduced by dahlgaard & setijono) for transforming quality cost measurements into value of quality improvements(ROQI). The two used models in this paper have been theorically developed and examined in a Swedish wood-flooring manufacturer. The data analysis results in present study suggest that quality improvement efforts do affect on quality improvement indicators, and model validation is reconfirmed.By converting quality costs measurements into value, a better explanation concerning the effect of prevention and appraisal activities on the quality improvement indicators would be provided. Thus, the value of quality improvements is a measure of return on quality improvements (ROQI), which reveals whether the quality improvement efforts gave higher, fair, or lower return.
