Imagine a rowboat. Now imagine a group of world-class athletes rowing. If they all row in the same direction, the boat moves. If they all row in opposing directions, the boat, though well staffed, remains exactly where it is. Decide on a process and follow it.
Process is the framework that supports the project.
It determines how groups on the project interact and what tasks need to be done when. Without a defined process, issues fall through the cracks, or team members must spend time following up to make sure things were done. Any process should be flexible enough to handle unexpected events, but rigid enough to keep cowboys in check. Communicate project status clearly and honestly. The worst mistake any manager can make is to lie about the status of a project.
