As in most situations, start first with the easiest option; it might just work. Bring the problem to the attention of your co-worker. They may not have known they were making things more difficult for you. Or maybe their intentions were good, but they didn't really understand the procedures or the reasons behind them.

John Kotter and has produced a great book that contains a wealth of wisdom and insight. While it looks and reads like a simple book, it is anything but simple.

You'll want to document all of what you learn, so take careful notes during the meeting and afterward send your manager an e-mail outlining the highlights. Having these issues clarified should give you more confidence as a leader. Next, meet with your new team to explain how important their talents and contributions will be to a successful outcome. As the project progresses, remember that many of the same rules for general management and employee motivation apply for team leaders: open communication, sound guidance and recognition for a job well done. Once you've taken responsibility and acted to fix the situation, stop beating yourself up over it. Everyone has made mistakes at work, some probably far worse than yours.
