Years ago, Roy Osherove interviewed me about project management, agile thinking, hiring, and management. We had a great conversation. (See Roy's Archived Interviews page for my interviews with him.) I just listened to some of the questions and answers. If you are not sure about effective management, listen to the interviews.
Roy and I have both grown and changed in the past 12 years. (Thank goodness!) We focused much more on agile issues in this interview. Roy provides an unedited transcript, so you might find the issue you're interested in faster.
Some links to some of my thinking on:
Roy, thank you for such a great conversation. Maybe we won't wait quite as long the next time!
