Project Manager

Once you know that you have a project, you need to find someone to make it happen.  A project manager is the person who is uniquily responible for the execution and success of the projet. PMI says it best in the 2000 edition of A Guide to the Project Management Body of Knowledge (PMBOK® Guide):

Project management is the application of knowledge, skills, tools, and techniques to a broad range of activities in order to meet the requirements of a particular project. Project management is comprised of five processes - Initiating, Planning, Executing, Controlling, and Closing - as well as nine knowledge areas. These nine areas center on management expertise in Project Integration, Project Scope, Project Time, Project Cost, Project Quality, Project Human Resources, Project Communications, Project Risk Management and Project Procurement.{1}
