Scar and Letter - | Component Engineering …

1 CE CONSULTANTS DOUGLAS ALEXANDER 1 Instructions for completing a SCAR Please Contact Components Engineering @ _____ When you have begun the SCAR study. 1) Problem description: Describe the problem in terms of what, where, when, how big, etc. Please continue to ask WHY until you get to the real base problem. Determine what the problem IS and what the problem IS NOT. 2) Containment actions and date effective: Identify the containment action (s) for the symptom. Identify completion dates for all actions. Verification: Describe the method to verify the symptom was eliminated.

2 This could include capability studies, pilot run, DOE, bench test, etc. 3) Root cause(s): Root cause is determined by identifying differences between the IS and IS NOT parameters of the problem description. Determine changes that have occurred and evaluate if the change could explain why only the IS occurred and why the IS NOT never occurred. Both occurrence and escape should be addressed. What went wrong to allow the problem to occur? What went wrong to allow the problem to pass undetected through the process? Verification: Describe the test made to verify the root cause.

3 Can the defect be made to come and go? 4) Permanent corrective action and date effective: Must directly address the root cause. Identify the actual or target date for the permanent corrective action . Verification: Describe the test made to ensure the corrective action totally eliminated the defect associated with the root cause. Describe steps taken to detect any undesirable side effects. 5) Controls: Describe the controls used to ensure the corrective action remains in place and is successful. Statistical Process Control is a form of control.

4 6) Prevention: Identify what systems, practices and procedures allowed the problem to occur. Describe the revisions made to practices, policies and procedures. 7) supplier leadership signatures / Title / Date: All problem solving team members must sign and date the form. Titles must be listed. CE CONSULTANTS DOUGLAS ALEXANDER 2 supplier corrective action request Vendor Part Number Original PO # Factory Date Code if Available supplier or Distributor: Date: Our Company P/N: Date Code: Problem Description: supplier is to complete the following corrective action documentation.

5 A separate report may be utilized. However, all of the items shown must be addressed. Periodic updates are to be provided until permanent corrective action is complete. Failure to provide adequate resolution to issues could lead to removal from the Approved Vendor List, (AVL) 1. Problem description: _____ 2. Containment actions and date effective: _____ Verification: _____ 3. Root cause(s): _____ Verification: _____ 4.

6 Permanent corrective action and date effective: _____ Verification: _____ 5. Controls: _____ 6. Prevention: _____ 7. supplier leadership signatures / Title / Date: _____ _____ _____ _____ Acknowledgment of supplier Review and Disposition Date: Approved by: Rejected by: CE CONSULTANTS DOUGLAS ALEXANDER 3 To my fellow CEs, Probably no corrective action process should be more closely monitored than the process initiated by a supplier corrective action request or SCAR as it is commonly referred to.

7 It is a good idea to create a calendar reminder from the date you initiated this request with additional dates to call and check on the progress of the failure study. If the failure created a line down incident, then you want to immediately investigate an alternative part, alert purchasing to hold all incoming orders, and advise Manufacturing and/or Sustaining Engineering that you have given this a top priority. Keep them advised and in the meantime, initiate a TMD effort to get the line going again. This Letter below is an example of the serious tone that should accompany your SCAR request form to the supplier .

8 Feel free to use it word-for-word. To Whom it may Concern, Please expedite this SCAR response as we are currently using a Temporary Manufacturing Deviation part to continue to build our products. It would be very much appreciated if you would call as soon as you commence the SCAR investigation. My contact information is below. In order to reinstate the use of this part into our manufacturing process, we will need a complete ROOT CAUSE ANALYSIS (RCA) and a statement demonstrating that the fix is underway and there are Materials.

9 Design Process, or Procedural changes now, or soon will be in place to prevent the same failure from reoccurring. Thank you, Douglas Alexander, CE
