OK - The focus is on processes. Does that include shipping? Off line inspections?

The LPA's I have seen generally included questions about inline inspections, first piece inspections, and final inspections. Those can be offline at many companies.

Packaging is generally included, so I would think it could extend to Shipping, as well.

Re: Layered Process Audits vs Internal System Audits

They cannot take the place of internal audits. As discussed throughout this thread, they are different in a number of ways. If properly constructed, they could fulfill the requirements for Manufacturing Process Audits (TS cl 8.2.2.2).
Yea, that is where I went. I first was going to make a distinction between LPAs and TS Manufacturing & Product Audits (see 102506 overview), but since management was so into the LPA I am in the process of modifying the LPA to cover both the manufacturing and product audit requirements (see 111006 overview). To make the LPA work for me (A Cove Principle), I went with the following wording to deal with the objective and impartial requirements:

Auditors performing LPAs are to be knowledgeable of the process for planning and
executing the manufacturing processes as well as the controls for ensuring that only
defect free product is released to the customer. Due to the multi-disciplinary approach to
planning and executing the manufacturing process, a LPA will most likely be performed
by an auditor who has played some role in the process. The coordinator of LPAs is to
ensure that the objectives of LPAs are understood by the auditors and that their conduct
and audit reporting are objective and impartial.


Still Working It!

I would like to edit my input to this thread. How can I change attachments I have entered?
'Edit' your post. You'll get the 'mini' edit window. You'll see a tab/button that says 'Go Advanced' - Click on it and it will take you to the full editing mode window. Scroll down a bit and you will see a tab/button that says 'Manage Attachments'. There you can Delete and Add attachments.

NOTE: Editing of posts is open for 7 days from the post date except for Moderators and Administrators. If anyone needs to edit a post after 7 days, just let me know and I'll help. This is set at 7 days because a few years ago someone came in and deleted every post they had posted, and deleted every attachment, going back a couple of years. I don't know why, but I didn't think that was quite 'fair'. It screwed up a lot of discussion threads.

Layered Process Audits are a Customer Specific Requirement from some customers. Hopefully, it is different than your Manufacturing Process Audits.

Manufacturing Process Audits ideally should be an in-depth review of the details of a particular manufacturing process. Most companies have trained auditors take a control plan and walk through all the checks, all the gages and documents, etc.

Layered Process Audits are promoted or required by certain customers as an additional activity. The framework typically is a one or two page checklist which is a fairly short overview of a particular product being produced. The "layers" come from different levels of managers participating in the same audit. Floor Supervisors, Area Managers, all the way up to top managers are intended to audit the same activity. The perceived benefit comes from the idea that different ranks of managers will see the same activity from different perspectives and might see weaknesses or improvements that others didn't spot. There is also the aspect that higher managers with greater authority are involved, which could bring additional benefit.

So, the two audits audit the same work cell, but in significantly different ways. However, you are free to adapt the techniques to suit your needs, because there is not much written as to mandatory approaches. Most is guidance type information, except customer requirements training such as DCX provides.
