Determining Objectives

When determining metrics, select metrics that are global to the entire operation. Then select metrics that support those global metrics. Break the metrics down by department, process, organization function or product.

The metrics have to be agreed upon. A management committee determines the metrics. Senior managment communicates these metrics through out the company.

All employees should be able to identify the metrics. All employees should know how their work affect the metrics.

Make metric targets reasonable and challenging. Management provides the plans to achieve the targets. During the quality management review, review the metrics and document the plans to achieve the targets.

Some companies put the quality objectives within the quality assurance manual. I do not recommend this. Your customers do not need to see your quality objectives. In most cases these are confidential.

Quality Assurance metrics are a key component of ISO 9001 requirements.
