Abstract

This study aims to evaluate the cost of obtaining quality (CoQ) of a multinational company in Tangier specialised in wiring. It also tries to identify the measures that can reduce the cost of non-quality and improve productivity time and there by improve competitiveness. According to our study, the CoQ represents 14.5% of the turnover including 10.4% of non-quality (internal and external failures). An analytical study was carried out concerning the quantification of all the components constituting the internal anomaly. It showed that machine stops have a significant effect on the increase of internal failures. To detect the main causes of non-performance, DMAIC, SMED and AMDEC approaches were used to decrease non-productivity time. This allowed the company to gain 41.3 days/year relative to each machine, which contributed to increase productive time and to generate an annual financial profit of 361,370.24 € (as a reduction of the non-quality cost of 6.36%).
