Russ, we do annual material certifications on all products we produce and we also do quite a bit of development work for new materials.
The reason I asked the questions is because I am trying to write a Quality Manual for ISO17025. This is what the guidance manual I'm using states for 4.11 - Preventive Action:
Preventive action is a pro-active process to identify improvement opportunities, rather than react to the identification of existing problems or complaints. The policies and procedures should reduce the likelihood that a non-comformance will occur. Apart from the review of the operational procedures, the preventive action might involve analysis of data, including trend and risk analyses and proficiency testing results. Once a need to improve has been identified, an action plan should be developed, which includes tasks, assigned responsibility and timing.
Once the plan is implemented, it should be monitored to verify that the needed improvements have been realized and effective. There should be some evidence that a follow-up of the effectiveness of the preventive action has been performed. Several methods exist for doing a follow-up. One method is a formal process by which each preventive action is reviewed and the effectiveness is evaluated. The effectiveness of the actions should be evaluated within a reasonable amount of time to assure that the activity has not slipped into nonconforming activities. If it is discovered that the corrective actions are not effective, the laboratory should have a process for ensuring that further investigation is performed to determine why the actions were not effective.
Whew! OK - have you read this over...do you understand why I'm confused. How do you write a policy and procedure to cover this?
