I respectfully disagree. Even in ISO 9001 (which is no more than "Basic Business Practices 101") incomplete forms (which become records) are going to be problematic.
You are correct in saying ISO 9001 does not explicitly require that forms be completed - But just consider the aspects of responsibilities (e.g.: no name entered).
Relating non-completed forms to "business performance" is not appropriate in my opinion.
A "Form" with omissions is no less than an "in-complete" record.
Marc, I was thinking in broader terms of "information", not just the completeness of paper forms, but also the use of electronic data (which too qualifies as "records") as an input for decision-making. If negative trends begin to manifest themselves, a lack of meaningful information may lead to missed opportunities, so I believe (in this context) it is appropriate to relate to the business performance angle.
For example, if a large company experiences a sudden increase in product failures but (because of poor IT planning) their shop floor control data does not provide traceability to specific users, an opportunity was missed either to re-align the under-performing individuals to the related objectives or to re-assign them to less critical tasks, thereby allowing those persons to continue to operate undetected. This can significantly affect business performance in a negative way, if not corrected in a timely manner.
I do think that Helmut summed the "paper form" thing up with:
A nonconformance is a situation where someone is not doing what is expected. Lots of companies have forms where not all fields are not filled out. Is it right? Is it wrong? We could debate for a long time.
Some information is clearly necessary, depending on the form. As an auditor, if it appears there is meaningful information missing, it would be an audit trail. It frequently leads to a nonconformance against records. If non-meaningful info is missing, I would probably just move on to more meaningful discussions, or perhaps suggest they modify the form.
