Matthew Evans,
The use of numbers and revisions is optional, being only the conventional, and not the only possible, method of control. When numbers and revs are used, they apply only to procedures and forms and will be applicable, of course, to the procedure which describes the planning and implementation of the internal audit. The actual schedule is not a procedure. It may be on a form but there is nothing in the Standard to say that it must be. Basically, a schedule (by definition) is only an ordered list - not necessarily a dated list. It can be on the back of a postcard for all that it matters, or it could be only a verbal agreement.
In fact, the second paragraph of 4.17 (the only mention of scheduling in the Standard) gives us leeway to initiate or postpone audits according to perceived need rather than use a dated list. (This relates to the flexibility to changes in circumstances mentioned by David and Lurker above) For example; I can imagine an organisation where the decision to hold, or not hold an internal audit, is made at Management Review, depending on the current situation and imminent events. This method might have become the conventional approach from the time the first edition of ISO 9001 was introduced, had most of us not already become bound by the chains of bureaucracy. There is nothing in the Standard to prevent this approach and it has a lot to commend it. It would align the implementation of ISO 9001 more closely with Deming, particularly regards items; 2,3,5 and 7 of his 14 Points For Management and conform to Shonberger’s advice to eliminate waste throughout the organisation.
In such a case, the minutes of the meeting, filed anyway as the quality record of Management Review, would provide both the schedule and the quality record of scheduling. (Note; the control of quality records is a different subject entirely)
Please don’t hesitate to call me mad, if that is what you think, but be sure to tell me where I’m wrong, and don’t let it be just your opinion; back it up with evidence from your experience and, most of all, evidence taken directly from ISO 9001 since that is the document under consideration and furthering of our understanding of compliance with that document is the object of these discussions. Whatever else we get from these discussions, we all want to learn.
Respectfully yours,
John C
