Hello All,

             Can you please give me an example of Root cause analysis for Improper use of Temporary Fasteners?

 

Thank you in advance

Ah good old Cellotape engineering!

 

If, for whatever reason, we have to use temporary engineering, and lets be honest sometimes you do as it's not always feasible to stop a line and do repairs there and then (compromising the product or having to wait for a specific part), I carry out a documented risk assessment, take a sample of the material used, photographs, and complete a log with time scales and responsibilities. I then sign all of this off when the work is complete and has been inspected by myself and the engineering manager.

 

Not quite a root cause, but at least it demonstrates that your in control. Our engineers on site were more than happy to help complete the paperwork (as were the production managers, as it often reduced downtime)

Is this support for BODGIT engineering and the root cause the people that encourage, practice and support it?

Also if you write the date on it really big it shames them into fixing it faster.

Dear hmcdonald,

 

The intended recipient of yr RCA is unmentioned. Could be relevant.

 

IMO the main problem in doing an RCA is knowing how/where/when etc to stop. :smile:  Suggestions for this can be found in numerous previous threads on this forum along with all the basic methods, 5W, fishbone etc. Unfortunately few actual process examples are given. Most indicative tables in the literature/regulations  seem to focus on structuring via particular segments although some events can be highly complex due multi-factor causes.

 

Although not food related I found pages 67-77 of attached specialised SOP easy to read and helpful in getting an idea of the principles behind RCA (or at least one viewpoint on such). The tabulated examples included are also edifying IMO. I have separately attached the overall (blockbuster) RCA tree which depicts the potential defect routes.

On the other hand, specifically for food, here is BRC’s handout  on RCA which  (presumably) also relates to their audit expectations, some useful tabular examples are included along with tips for 5W, fishbone etc.

(thanks to Scotty)

 

And to further show how minor events can lead to non-minor analyses (if one wishes), here is a detailed worked example for a car-owner’s problem utilising one of the, claimed, simplest of RCA techniques -

(preferably compared with 5W section in BRC above and in link at bottom)

 

I suggest to confine one’s RCA scope to the requirements of the targeted recipient as far as possible. :smile:

PS – this link concisely compares 5W, fishbone etc with respect to their pros/cons in a quite useful way.

(also see pages 55-66 of first attachment which has a more detailed evaluation)


Kind Regards,
