The report includes Corrective and Preventive Actions implemented as a result of a customer product complaint. Customer product complaint was received related to cosmetic defects of the Dura-Padz assembly. The defects found were scratches, dents, molding flash, de-bonding and stains. Supplier Corrective Action Report (SCAR) was issued by the customer to figure out the root cause of the problem and implement effective measures to address the root cause of the defects. The purpose of the project was to determine the root cause of the above mentioned defects and take corrective and preventive actions to address the root cause. 5 why methodology and Measurement System Analysis (attribute gage R&R) was used to determine the root cause of each of the defects. After the root cause was determined for the defects, corrective and preventive actions were implemented to address the root cause. After the implementation of corrective and preventive actions, effectiveness check was performed to see if the actions implemented were effective in addressing the root causes. The results from the effectiveness check showed that all the corrective and preventive actions implemented were effective in addressing the root causes.
