...

• Percentage Contribution: If there are multiple sources of the problem, they should be listed and their percentage contributions proportionally assigned. Important! The sum of percentage points must equal 100% - otherwise, the system will not allow sending step D4 for approval.
• Problem Description: Here, the supplier must descriptively state what is or is not the cause of the problem.

Step D5-D6 - Permanent Corrective Actions and Their Verification

Step D5 - Corrective Actions

In step D5, the supplier is asked to present planned corrective actions. The aim of these actions is to ensure, in the short term, that the process or product is under control. The supplier selects optimal (permanent) corrective actions and demonstrates, based on tests and trials, that they solve the problem from the client's perspective.

The form is divided into two sections:

1. Improvements in the process that caused the material defect: The supplier indicates possible causes and describes the corrective action taken.
2. Improvements in the process that allowed the shipment of defective material: If the complaint concerns the shipment of the material, the supplier is obliged to fill in this section.

Step D6 - Verification of Corrective Actions

The effectiveness of the corrective actions is assessed in step D6, which is described as the verification of the effectiveness of corrective actions.

• Assigned Employee: The person responsible for implementing the action.

To submit step D7 for approval by the Buyer/QA, at least one preventive action must be provided.

Submission and Approval

• D7 Rejected: The supplier should review the comments and make the necessary adjustments in the D7 form. After making the corrections, the approval process is repeated.

Step D8 - Summary / Team Efforts

The final step, 8D, involves evaluating the actions implemented in 7D and formally closing the actions and dissolving the team. Additionally, this step serves as a summary, documenting the results of the team's work in an 8D report and acknowledging the team's efforts. A PPM score is also assigned. This final step is completed by the Buyer/QA.

Upon completion of the summary, the supplier receives an email notification about the pending evaluation.

Supplier Actions:

1. Log into the System: The supplier logs into the system and navigates to step 8D, where the evaluation form along with potential complaint costs are displayed.

Depending on the supplier's decision, they will:

• Approve: This confirms the supplier accepts the actions taken in steps D5-D7 and agrees to any associated costs (if specified). The complaint process is concluded.
• Reject: If the supplier has comments regarding the summary or potential costs, they should note them in a dedicated popup window. The complaint is then sent back to the Buyer/QA for review. After verifying the supplier's suggestions, the Buyer/QA sends step D8 back to the supplier for re-evaluation.

Approval Scenarios:

• D8 Approved: The supplier has accepted the complaint process summary.
• D8 Rejected: The supplier has rejected the complaint process summary.

Finally, if all steps have been approved and each step was completed within the specified deadlines, the status of the complaint is changed to 'Completed,' which concludes the complaint process.

Both the supplier and the Buyer/QA can download the complete 8D report in PDF format, print it, and submit it to the documentation department.
