Use audits as opportunities to train others. Ask for a volunteer (who is not an auditor) to walk through the audit process with you as an assistant. This will provide others with a better understanding of what audits are and why they are necessary.
Invite all the auditees to the closing meeting. Having been an auditee, I know it helps to hear audit findings firsthand, the positive as well as the negative.
Involving people creates a feeling that everyone is a vital contributor to the goal of the company - compliance.
