KEY METRICS USED TO ASSESS COST OF QUALITY
■ Typical Cost of Quality metric, comprising of prevention, appraisal, internal failure, and external failure costs.
■ Two overarching metrics are used to monitor overall progress: 1) cost of quality (CoQ) as a percentage of sales,
and 2) CoQ as a percentage of cost of goods sold (COGS).

11. MEMBER PERSPECTIVES ON COST OF QUALITY
An Interview with Merix Corporation
What are some of the factors that influenced your choice of metrics?
Merix just started measuring cost of quality in 2008 when George Dramowicz joined the company. There was a strong interest from the CEO
and the Board of Directors to look at this data. In fact, the request for gathering and monitoring this data was communicated to George
during his first meeting with the CEO, on the first day of his employment with Merix.
How do you calculate cost of quality?
George Dramowicz The cost of quality (CoQ) model at Merix includes prevention, appraisal, internal failure, and external failure costs. It is based on the Certified
Vice President Management Accountant (CMA) cost of quality guidelines. The dollar value of each cost element within the model is pulled from a specified
of Quality cost center value within the existing accounting system. Merix then estimates the percentage of that cost center value that should be
allocated to CoQ. As such, there is minimal dispute across the organization about the validity of the data.
How often and to whom do you report these costs?
CoQ data is collected and reported on a quarterly basis. Quality leadership shares this information with the extended senior management
team and the Board of Directors during quarterly business reviews. During this session, the group reviews the cost of quality as a percentage
of sales and as a percentage of standard unit cost (PCB panel) globally, as well as for each site. Quality also presents the distribution of quality
costs across the four categories and the level of improvement in each category in percentages and absolute savings. The group then analyses
the reasons for cost variation.
What type of decisions do you make based on the data?
Erika Johnston
Cost of quality data analysis enables Quality to monitor cost variation in each of the four categories both at a global and site level. Quality also

of those costs.
Operations
Do you anticipate any future changes or improvements to your cost of quality approach?
The Quality organization is confident that their existing approach is optimal for their current needs. However they do continue to tune up the
model at the end of each quarter based on new trends and their reactions to observed variations. With a mature model in place, Quality plans
to focus more on CoQ reduction projects.
Are there any lessons learned that you’d like to share with other companies?
