The answers you get will be worth more than a whole flock of McKinsey consultants roosting in your company for a few months. The answers are there. Just find a way to empower people to tell you what they know about you, and how you're misunderstanding some critical things about your business, but are afraid to share with you. Finally, Marilyn, I need to respond to your comment about benchmarking salaries. Of course money is important.
People have to be paid a fair and livable wage.
But money is vastly over-rated as a predictor of work satisfaction. Talk to the people there about what's working and not working, and what their suggestions for fixing things might be. And while you're at it, say a little prayer of thanks for your brave new HR director. She's in the process of saving you from yourself.
