So now I'm going to say this - beware of becoming the overly confident project manager. I realize this basically goes against everything that I've been saying, but it definitely can become a problem. We must be confident, of course. But left unchecked the overly confident project manager may make some serious mistakes, including:
Make key decisions without key stakeholder involvement
Sometimes project decisions have to be made on the spur of the moment and at any given moment when a key decision is required, few if any of the key stakeholders may be available to help with a that decision making process. But when they are available – and that is most of the time – they should be utilized. Not that you always should include them, but there are decisions where key stakeholder input – and certainly project team member involvement – should sought out and utilized. The overly confident project manager may start to make key decisions without the proper amount of consideration put into the decision being made – including utilizing the experience and expertise of the team and key stakeholders surrounding him.
