For each month's audit committee, I started reviewing a one page spreadsheet. Down the left are all of the audits to be completed and across the top are fieldwork, report, responses and expected completion date.
This has worked well for me this year. Only once has the audit committee had to ask a dept head what the holdup was. Word got around and I have had incredible turnaround ever since.
And, like was just said above, it lets the committee and the examiners know that I have finished fieldwork. (Never hurts to cover your own.)
