Over the shoulder technician audit
« on: 10-29-2010 -- 12:14:29 »
My supervisor asked me to do an over the shoulder audit on the calibration technicians.
We really don't have a quality department yet. . . but we want to start the process and begin with over the shoulder audits.  Myself and most of our techicians have been PMEL trained so they know what they are doing, or should be doing.  We have a full service lab covering RF/microwave to electronics to physical and demensional equipment.  I've been through enough of these over the shoulder quality checks myself to know the basic questions about the proceedure being used, equipment substitution, are you formally trained on this piece of equipment. . . etc, etc. 
However. . . I was wondering if anyone had a nice template of questions already put together you might be willing to share with me. 
Thanks for reading my post. 
Scott.

When I was in the A. F. , our quality guys would sit down with us and actually watch us go through a calibration/proceedure step by step.  I think I want to impliment this process or something like it sometime in the future. . . but what I am referring to here is just a quick surprise check list. . . . Here is what I have put together so far:

Impromptu (over the shoulder) calibration technician quality audit check list. 

Technician:             Section:            Date:

Auditor:

Calibration, Repair, Troubleshooting:

What procedure is being used? :

Is the procedure current? :

Is the technician formally trained on this piece of equipment? :

If applicable, E. S. D.  practices being followed? :

When was the last time the technicians E. S. D.  strap was tested? :

Is the proper test equipment being used? :

Is the technicians work space generally neat and clutter free? :

Can you think of anything to add to this list?

I would get rid of the ESD questions. It's clownish. It has to be the most overrated concern in the business and it doesn't really add any value to the audit. Stick to technical questions and try to get a feel if the technician has an understanding of what he is really doing and not just pushing buttons. Any auditor asking me questions about ESD would lose any credibility he may have had.

Is the calibration label complete?

Is the environment within limits at time of calibration?

I have always found people are a bit more prone to choke up when undergoing these audits.
My preference would be to say little during the testing process, let the tech talk all they want. 
Discuss you observations/concerns/praise afterwards.

Well E.  S.  D.   practices are of paramount importance where I work, so I need to put that in there.   It's a HUGE deal here so I think that part needs to stay, especially if I walk up during the troubleshooting process and a piece of gear is actually open and being worked on. 
I like the environmental conditions question.  .  .  that's a good one. 
Discuss your observations/concerns/praise afterwards. . . . I like that also.  Always a good thing to give positive and constructive feedback. 
This list will be evolving so I really appreciate any constructive input.  .  .  I'll keep checking in.

Do your technicians have a checklist they follow? I'd start with that.

They follow regular 33K- proceedures for each calibration.
We also have our own quality manual and a few years ago I wrote an SOP for calibration technicians that they have all signed off on. 
Yes those are some of the guidelines I will be making sure they are following.

The SOP is what you probably want to focus on. Sit down with it and write out a checklist for your technicians to follow in order to standardize the process across your lab. When you do that, you will have your QA checklist.  :-D

what about updating the data base (pams for the AF) or master equipment list
