Upper management can benefit from having a core leadership group that can focus on delivering changes within the organization. These people can offer a clearer, more dispassionate view of the business because they’re not directly involved with any individual part.
A project management team will tend to be more critical of each individual piece of a process and have an eye toward the overall business need. Unlike middle managers, program managers do not work day to day within an operational group or division. This provides a more independent view of the organization that can then offer specific alternatives to the company. With no axe to grind or turf to protect, the project manager is much more able to offer clearly defined changes that benefit the company and the bottom line.
