My Life with ISO 9000
My Life with ISO 9000
My employer (which isn't an electrical contractor ...) is ISO 9000 certified and has been for 10 or 15 years now.
ISO is great if your company's culture already does the sorts of things ISO certification requires, and the employees buy in to it. But if the corporate culture is opposed to the restraints that come with ISO certification, or the employees hate it, it becomes something else to work around and there are plenty of ways (some of which are legitimate) for getting around it.
The key parts of ISO are documenting all procedures, having a formal process for changing processes and procedures, documenting and retaining test results, and I think you also have to analyze test results.
iwire's comments about trucks having identical inventories is, as others pointed out, incorrect, unless someone within the company decided that all trucks must have identical inventories, or that only certain parts could be on a truck. What it would requires is that for any given task, there be one or more procedures, all procedures be documented, the employees who perform a task know the procedures for that task, and that they know where to find the documents which describes the procedures for performing their tasks. ISO 9000 can be summed up as "Saying what you do, doing what you say, and proving it was done how you said it was done." That's about it.
Regarding Bob NH's comment about notebooks and the "this is an unofficial copy, valid only at the time of printing", we deal with that as well, and when I write ISO documents, I include that language. Although it seems absurd, it's not that absurd in practice since anyone who wants to know if the document is valid need only look at the "official" on-line source and validate the version that's on-line against their printed copy. Each printed copy should list the location of the on-line copy as well as the review interval. In the non-ISO world there might not be a requirement to have an "official" copy and then you wind up with each person having their own "procedures" and the chaos that can result from that.
