This paper reports on a method (quality management activity planning-Q-MAP) for mapping quality assurance procedures, information flows and responsibilities. A comparison is made of the ICAM definition (IDEF) method and Q-MAP as to their suitability for mapping quality assurance systems and fostering the advancement of the quality improvement process. The achievements arising from the use of Q-MAP at Garrett Automotive Limited are examined. It is pointed out that the involvement of employees in the preparation of Q-MAP diagrams has led to improvements in processes and procedures by eliminating differences between actual and documented work practices and that a wider cross-section of employees are now familiar with the company's quality assurance system.
