Hi

 

We are contract packers for manufacturing and exporting companies.

 

We received a complaint from one customer that the box of concentrate sachets of 8 had two sachets missing. We have hourly inspections and continuous checks in the process to ensure the total amount (8) of sachets is in the box (the sachets are counted by hand before being placed in the box).

 

Our customer wants a Root Cause for the missing sachets as well as a Corrective action.

Pleas help?

Hi

Have you performed a root cause analysis before?  It can be a helpful tool if you get the right people involved, and not just management.  We use the 5 why process and include someone who is actually doing the task in the meeting. We then define the problem and include all the conditions from that day.  From that point we list possible causes of why the issue could occur .  Once we have our possible causes, we develop our 5 whys that lead us to our root cause.  From the root cause you develop a corrective action plan.  

 

Brief example (not knowing your entire process or conditions that you have in the facility)

Define the problem:  One case had 2 missing sachets.  We were short 5 people that day and had temporary employees on the line.  We were also behind on schedule and had the line speed increased. We reviewed our inspection records and found all were in compliance.  One hourly inspection was missed.  

Possible causes: Lack of training, sachets dropped on the floor, inspections not frequent enough, line moving too fast

 

From this point you would go into your 5 whys (Why was the case short 2 sachets?  Because the employee did not put them in the case Why did the employee not put them in the case?  Because he was not trained

 

Your root cause could be you have new employees on your line and you need to review your training at hire.  Preventive/Corrective Actions could be to notify them of the complaint, retrain your employees, and increase inspection frequencies.

Again, not knowing all the details around the situation I'm just giving some examples to get you started.  I also attached a form that we use as an example. Hope this helps!

Hello,

 

Attached is a simple form for corrective action. The simpler and more concise the form, the easier it is for your team to adopt the form. The style of Corrective Action is called Closed Loop Corrective Action and it employs the 5 WHYS for the root cause analysis component. Attached File  Template_Close Loop Corrective Action .docx   20.71KB   67 downloads
