The difficulties in implementing the COQ approach are as follows 鈥�

1) Measuring the quality cost is the major difficulty as every cost cannot be measured like profit loss due to unhappiness of customers.

2) Another difficulty in implementing this approach is the lack of knowledge of using this approach efficiently.

3) Another difficulty arises due to the lack of needed tools to collect, organize, filter, and report quality costs.

Alternative approaches to COQ

Alternative approaches to COQ are as follows 鈥�

1) Poor Quality cost 鈥� This is the improved model and ignores the prevention and appraisal costs as they are problematic to measure.

2) Total cost of quality 鈥� TCOQ model differs from COQ in the sense that TCOQ does not include maintenance and quality training costs as in the COQ model. Thus it is not a preferred model as that of COQ.

3) Qualified function development 鈥� QFD was developed to understand the customer requirements and maximize the quality positively by creating a comprehensive quality system.
