The Eight Disciplines |
| 1. Select the Team |
| |
| |
By using a team approach, the benefit of a diverse but experience group of people develops a cohesive plan for problem correction and also lays the foundation for training in problem avoidance. |
| |
| 2. Describe the Problem |
| |
| |
Describe the change in condition or pre-existing condition which caused the problem. Express the condition in quantifiable terms. Data should be included for proof of the need to initiate a corrective action in the first place. |
| |
|
| 3. Describe the cause |
| |
| |
Describe why the cause of the change in condition occurred and hat caused it, or identify the "holes" in the system which allowed the preexisting condition to go undetected. The cause should be described by the team members of the department that contributed most to the cause. |
| |
|
| 4. Implement Containment Plan |
| |
|
| |
Describe who, what, when and how the defects will be captured and contained, and how they will be prevented from getting to the customer. Consider the effect of the containment plan on factors such as cost, delivery, and inducement of other types of defects. Consideration should be given to material that may be affected (inventory or as work-in-progress). The effect on customers who may have already received such materials should be reviewed. |
| |
|
| 5. Implement Permanent Corrective Action Plan |
| |
|
| |
Describe who, what, when and how changes will be implemented to totally eliminate the root cause of the problem. |
| |
|
| 6. Prevent Recurrence |
| |
|
| |
Describe the internal and/or external cultural or systematic changes that must be made to prevent the problem from recurring. Preventing recurrence is the most difficult of the eight disciplines to organize. If recurrence should occur, then a new 8D-CAR should be issued referencing the original so that it may be used as a learning process in improving the effectiveness of the corrective action process. |
| |
|
| 7. Verify Effectiveness of Actions |
| |
| |
All follow-up actions are verified by the Quality Assurance organization to ensure the effeteness of the actions taken. |
| |
|
| 8. Congratulate Your Team |
| |
| |
If everything is found to be satisfactory after reviewing accuracy and discussions, congratulate your team on a job well done. |
