I'm not a TL specialist, and it's obvious there aren't any who visit here regularly because it's really a niche 'market'. However, QS-9000 is very keen on Disaster Recovery so I'll give this a shot.
First one must remember that most companies can only go so far in disaster recovery - plans for or not. If I have a shop that makes wire harnesses and I employ 150 people I may (for example) have a contingency plan for one of my suppliers folding. But how far can and should I go? I may have alturnate suppliers in mind but if I'm not going to place an order with 'alturnate' suppliers I can't ensure they will even take on extra business. Heck - they may be wiped out in the disaster which wiped me out.
The first thing I do is list possible disasters and 'suppose' what I can do in each case with respect to reality. For example, if my plant is destroyed completely in an earthquake or tornado I cannot have a plant set up somewhere else ready and waiting to take over production (remember I'm a small supplier).
So - take the list and address each issue with your intention or actual plan. Some can be real - for example I can have a data backup in San Diego while my plant is in Toledo. I did some work for an insurance company which had 3 geologically distant locations and data redundancy at each. They could sustain a loss of one entire facility (and theoretically 2) and still maintain their business without interruption. They didn't have manufacturing equipment, however so it was really a no brainer.
I can understand your comment about smoke and mirrors but the reality is there is no company which can really have in place a contingency plan for every possible disaster. You listed:
-Suppliers (what backup plans were in place)
-Materials
-ERP System (IT Disaster Recovery)
-Manufacturing ability (in other words if site A disappeared, could site B continue operations and deliver to customers)
I don't see a problem with the first 3 but the 4th would be (to many companies) impossibly expensive unless you're a quite big company. For many companies there simply is no 'Site B'.
I think what I'm saying is 7.1.C.3 gives some leeway to a company to address reality with respect to them. One could go so far as to say by ensuring a print exists and is protected against loss they can "...recreate and service the product throughout its life cycle...".
So - in my example company I make my list and lay out contigency plans for what I can 'control'. I suggest you take a read through
http://Elsmar.com/Forums/showthread.php?t=238 which is a consolidation of several threads from the 'old' forums on contingency plans with respect to QS-9000 for some thoughts.
You end up stating: "...Without having the actual 'methods' in place, it seems to expose the company to quite a bit of liability..." For what a company can realistically control I agree and 7.1.C.3 does not give a company an out as I read it. What 7.1.C.3 does not do is define how or what. If you would like to discuss this in more detail, I'll be happy to 'chat' here.
From what I can tell is you are saying that the company you are dealing with does not want to have defined plans. Is that correct?
