Root Cause Analysis Improper Date Code on Product

Best Answer Madam A. D-tor, 23 August 2017 - 06:23 PM

Dear Hasson 256,

 

To find the root cause it always helped me to ask 5 times "why?".

 

Example:

Deviation:                    improper date printing

why 1:                         why was the date printed improper?

answer (example):       because the printer was running out of ink

why 2:                         why was the printer running out of ink?

answer:                       because it was not filled on time

why 3:                        why  was it not filled on time?

answer:                       because the operator did not check the ink level on time

why 4:                         why did the operator not check the ink level on time?

answer:                       because he had no time/ forgot it.

why 5:                         why did the operator had no time/forgot it?

answer:                       because he was busy solving an equipment failure of another machine.

 

sometimes you need more "why?"s. Sometimes you find the solution sooner. If a question has more answers e.g. printer run out of ink and the finished product check was not conducted, than follow both answers again with why-questions.

 

Root causes are mostly related to: providing resources, providing training, maintenance, lack of time/ too busy staff, uninterested or unwilling staff, design of equipment, design/flow/layout of buildings.

Hi you will have to do your investigation once you have conducted an investigation that will determine your root cause. For example if a qa technician did not do a pre operational ink jet inspection along with the production supervisor that is your root cause. Once you have your root cause you will of course have to create a preventative measure and corrective action plan. Hope this helped you.

We have had a similar situation happen in our facility.  We were using a price sticker gun to apply the date code stickers and partway through the day one digit got switched.  

We already had in place a check at the start of production to ensure the date code was set correctly. 

With this type of system there was not much we could do to lock the gun to prevent this from happening so we implemented a midshift and end of shift check on the date code.  

If you are using an inkjet type printer and you did not have to change the code through out the day then you may simply need to implement a check at the start of the day to ensure the code is correct.
