How to measure the effectiveness of quality assurance.

Measuring is an essential component of any Total Quality Management System. In the Good Laboratory Practices arena this normally is done by measuring the quality of the customer's (e.g. Toxicology) output. This paper describes a holistic approach to measuring the effectiveness of the Quality Assurance Unit (QAU), which includes measures of both the customer and the QAU. When taken together, these measures provide management with a picture of the effectiveness of the QAU.
