hello ,

I need some recommandations to define root causes and corrective actions to the following non conformity

 

 

1. Root-cause analysis was performed, with Ishikawa and 5Why for both occurrence and non-detection root causes, but the Ishikawa was not complete and actually, the root-cause of occurrence was not correctly defined.

2. Even if corrective actions are defined, the main documents are not always updated (P-FMEA, Control Plan, etc.). 

3. 8D report is closed , without any evidence to follow the effectiveness of Actions ( production, Trials,.......)

 

what could be the causes of such NC 

and what would be the corrective actions 

 

this NC was detected in a customer audit and the 8D report was performed on february so what can i write as corrective actions please

 

thank you in advance

Sounds like you need to review the RCA approach adapted by your site. Ensure relevant training and procedures are in place to back this up and people involved in RCA from various departments are included. Review and follow up of actions prior to closure should be a part of this.


For a successful root cause analysis it is important to consider all the aspects of why the problem occurred in first place. Method / equipment / people / measure should all be considered as a potential factor. There could be more actions to resolve the root cause than just 1 and could involve more parties and departments. Setting smart, targeted actions, following up within relevant timescales and reflecting/reviewing if the approached method and actions resolved the initial problem or not are also essential otherwise the circle rewinds and other sources must be found.
