If you have good news about our program, give it to us straight, even if it means we won’t have to hire you to fix anything.
If you have bad news about our program, give it to us straight, even if you don’t know how to fix it, even if you think it will upset us.
I feel more strongly about the second request. We need to hear the bad news. We hired you because we want to improve. We need to know where our weaknesses are. It’s OK if you don’t know how to fix it right now because we knowing about the problem has already solved a part of it.
Your obligation to talk straight is the consultant’s version of “speaking up”.
