Project Managers, the really good ones, should feel very excited about their future. They have the core to great leadership – which most others do not. Filling the gaps for an executive position should be easy.
Project managers are some of the best candidates to fill an executive role, because to carry out their usual work they have to bring together all the disparate aspects of theory, reality, vision, process, finances, value, politics and human nature to create successful outcomes. Project managers often manage projects that cross all organizational functions and get to see the organization as a whole entity rather than from the "siloed" view of the projects or program.
