Abstract

Drinking water quality is of fundamental importance to human physiology and the durability of humanity. In today’s environment, many laboratories of water analysis are challenged to maintain or increase their quality while simultaneously lowering their overall costs. The aim of this research is to classify and determine different quality costs in Moroccan laboratory of water analysis by implemented the Prevention-Appraisal-Failure (PAF) approach. Using data collected during six month, we found that approximately 77.9 % of total quality costs was spent on costs of “good quality” (prevention and appraisal), while 22.1 % was spent on costs of “poor quality” (internal and external failures). This is an ideal situation, prevention costs will be the largest portion of the total Cost of Quality (COQ). By minimizing delay and Claims (retest) can reduced external failure cost laboratory given weighted to customer needs because of the good quality of service. The cost of processing and correcting such errors was minimum. The fundamental point is to monitor the effects of the quality measures taken to reduce the number of failures. The article also explains the benefits of the eventual adoption of a COQ approach in laboratory, proper frame work and we propose guideline for significant and non-significant factors which should consider in laboratory of water analysis.
