Corrective and Preventive actions are used to adjust the manufacturing processes, quality system and product documentation to continuously improve product and service quality. This process never ends. Corrective and preventive actions are usually based on an engineering change request and engineering change order system. In general it is recommended that all feedback from internal and external sources be entered into the engineering change request system. This can include customer survey results, customer complaints, nonconforming material data, field failure data, work-in-process testing results, internal audit results, external audit results and suggestions from personnel. The inputs are then entered into the Engineering Change Request System. This system is used to queue workload for the engineering and quality problem solvers. The engineering manager or quality manager then reviews this bulk of requests for prioritization. The highest priority issues are assigned to personnel who create an engineering change order to correct the problem. Some engineering change requests will be denied and the denial will be justified in the ECR system before the item is closed. Other requests will generate an Engineering Change Order that includes an assignment to a project manager. The engineering change order will include complete details on how to correct the problem and when the change will take effect. This system is a closed loop system that will continuously improve quality. The status of the ECR and ECO systems should be used as input for the management review meetings.

The process of managing this data usually requires a database since priorities change on a daily basis and the amount of input can be very large, even at small companies. A database is also advised since the system can be used to generate automated reports that are used in the management reviews. Without constant supervision, engineering requests and change orders can pile up and start dragging down the company. A database and procedure for managing engineering change requests and change orders is included with our QMS in a box product.
