• Submit the CAR form with the permanent corrective action plans and timing.
• Verify permanent corrective actions are effective.

Sun will analyze the final NRCCA response and provide the supplier with a decision on closure of the NRCCA.
CAR responses will be Accepted, Conditionally Accepted or Rejected. Resubmission of the CAR response
with discrepancies corrected is required within 5 days.

II. Problem Solving Expectations

When Sun initiates the Nonconformance Root Cause Corrective Action (NRCCA) process, suppliers are
required to submit a formal response. NRCCA responses must be in the format supplied by Sun. Below is
list of information that is required to be included in the NRCCA response.

a. Problem Statement
• Define problems in detail
• Identify “what is wrong with what”
• List Sun requirements concerning defect
• Identify when the problem started
• List manufacturing dates of defective material

b. Interim Containment Action
• Define and verify Interim Containment Actions
• Provide daily sort results
• All stock locations should be purged of suspect stock
• Describe method of sorting
• Validate effectiveness of ICA

c. Root Cause Analysis
• Define in detail the “true” root cause
• Verify the “true” root cause
• Address the escape cause (Failure in the process where the effect of the root cause should
have been detected and contained)
• Use the 5 Why approach or other problem solving tools

d. Permanent Corrective Actions
• Must address the root cause and the escape cause (why it happened and why it was allowed
to ship to Sun)
• Must be very detailed. Describe who will do what and how it will be implemented and
when.
• Verify and validate the corrective actions. Describe in detail method of verification.
• Corrective actions must not cause any other problems

e. Prevent Recurrence
• Modify necessary policies and procedures to prevent reoccurring problem
• Evaluate whether corrective actions can be implemented on similar products or processes.
