Forgot the part about skills!
You need to be able to communicate clearly, speak and be understood and most of all be organized. You have to know what the big picture is and what the end point that your running towards is, how you plan on getting there, and what your going to do in case something gets in your way. Basically follow the 6P rule; proper previous planning prevents poor performance.
Being a manager is a lot like being a babysitter, you watch over things, make sure everything runs smoothly, be available to reassure everyone that things are going according to plan, be able to deal with situations that arise in a politically correct and reasonable way, and have everyone thinking that your on top of everything all the time when in secret you feel like pulling out all your hair sometimes ;) It's about perception and making sure deliverables are delivered on time and that everyone stays happy.
