I do know what to do to fix the problem

revise the matrix
train people on accessing our onlice ISO system - again
will have proof of their additional training in training form - dated and signed by them
need to either make a new WI for those inspection specifications or just make a huge poster with faulty material pictures- post it all over production

and I have to fix that PA - change the format to CA and re - write it

the problems are root causes
that's where I got stuck

One of the best treatments on how to reply to ncrs is ANAB's "Heads Up" 137. You can find it on ANAB's web site. It is very complete while still being concise. Be aware that it is meant for a different audience, as is is written to aid certification bodies (registrars) respond to ncrs that ANAB writes against the certification bodies. It should be easy to see past that though.

The virtuos flow is to identify first the root cause ( the most probable), not backwards from the solutions, otherwise you can wrongly jump to them, but they will not fix the real root cause.
You can use some quality tools such as brainstorming, 5 why's, fishbone diagram, pareto analysis, is/is not method etcc for this purpose:bigwave:

Often, that's the hardest part. Most of the time, the root cause is hidden. It takes some detective work to dig it out.

One of the simplest techniques is 5 why. This originated from an oriental philosopher (who's name I have long forgotten) who basically said if you ask why enough times you can find the cause to any problem. Often, 5 is the magic number, but not always. It could take more or less.

Something to pay attention to, is that you may not be the best person in the organization to solve the problem. The standard alludes to it being the responsibility of the manager over the area where the nonconformance was found. It lease it specifically says so for internal audit nonconformances. If you are the management representative, your role should be to make sure it is responded to, and, if needed, be a coach or cheerleader to aid in getting it done. If that is not how it works in your organization, I suggest you have a talk with top management and try to help them to understand that ISO never intended for all quality matters to be the responsibility of the management representative.

Assuming that you can't shift the responsibility to where it belongs, enlist the help of the appropriate manager to help find the root cause. Sometimes it is also useful to enlist the help of the person working where the nonconformance is found. After all, they are the true expert. A wise mentor of mine once said the expert of any job is the person doing it, and as soon as you move as little as three feet away, you are no longer the expert.

I am doing it slowly but surely

going with the 5whys

that's what we / I did
performed corrective action as we do any other corrective actions in here
but now have to send the reply to the registrar

I have their guidance which is made of off that ANAB's Head up

naaa
in our small organization
the whole ISO is on me
Naaaaa, it can't be. Unless you're a one-person busienss? ie, the owner, the MD, the worker, the shipper, the checker and everything else?

In any quality management system, everyone has a part to play. Recall that underlying principle (one of 8 on which the Standard is based) is 'involvement of people at all levels' principle?

OK, perhaps you've got all the responsibility of maintaining/updating documents and doing the paperwork (again, not idea, but still) but the whole system? Nope.
