How to Write D3 Containment Actions of an 8D Report

When customers issue claims to suppliers and require 8D reports, many of them require preliminary reports up to D3 within 24 hours. In such preliminary reports, the most important part, undoubtedly, is D3 Containment Actions.

The purpose of containment actions is to quarantine the detected problem, and prevent it from occurring to the same and other customers again. To make the containment actions effective, one must identify and analyze all the products with the potential risk same as the detected one. These products include those on the customer side, those on the way to the customers, those stored in the supplier’s warehouse, WIP in the production line, and even the raw materials if the problem is caused by the raw material. The risk associated with all these products should be analyzed based on the historical production and inspection data. Re-inspection should also be conducted if necessary. Based on the analysis and re-inspection results, one then determines how to deal with these products. If risk exists, they should be recalled or quarantined.

The following template may be used to summarize the containment actions in the 8D report

In the above column of “Attachment”, evidences can be attached to support the analysis and inspection result. In the column of “Actions Taken”, the actions taken based on the analysis and inspection results can be described, such as recall or quarantine if the risk exists.

It should be noted that the containment actions should not be limited to the customer who issued the claim, and should also not be limited to the same products as the claimed ones. One must analyze whether same risk exists to the other customers and the other products. If yes, actions should be taken to quarantine such risk as well.
