If you choose to use ISO consultants we recommend you take advantage of your chosen registration company's pre-assessment audit (this is often free)
. Have their auditor come in for a day and assess various aspects of your system. He will appreciate the depth of evidence at this early stage and allow for it when making an assessment. Ask him to have them look at two, three or more processes - his feedback is often useful in streamlining top management's overall approach to ISO implementation.
