There are many sources out there that provide data on what quality folks make. But how much do you think a quality consultant is worth? That is, if you had to pay a consultant to help you, what would it be worth to you? I know what I charge, but what am I worth?
I don't know what you're worth. In Jan 2001, we contracted a consultant to assist with ISO9001:2000. That included apprx 11 visits, once a month until completion. We would complete assignments at that pace and be ready for a registrar in a year. Knowing full well that companies find it difficult to maintain this ambitious schedule, the consultant's terms were:
$4K each month for 3 months
Plus out of pocket travel expenses, billed at the end of each month.
Now, if the company decides to prolong the effort due to lack of resources or Commitment, he is paid up in three months and waits for you to call him again. If I were a consultant, I would insist on as much payment I could get up front as proof that the company is serious about this endeavor. Why would any company sign up for that and not follow through? Just ask me!
