There are considerable distinct differences between the project manager roles and project management. Let's deal with some of these differences right now. The central software project manager role involves strategic level thinking. This means that he or she is charged with instilling a sense of vision and direction for the project, managing members of the team, coordinating communications with managers across functional lines as necessary, delegating and supervising project sub-leads, establishing communication venues, and steering the aforementioned items during the process of the project management lifecycle.
Everything else can be considered project management support roles. These can be assigned not to the manager of the project, but to subordinates such as project leads, forecasters, project engineers, metrics specialists, and any number of other roles. The manager oversees the complete procedure.
That is just a basic distinction of the two roles, although there will always be some overlap across businesses, and even departments. The project manager is in fact the director of a particular project, and the people working under him or her are those charged with implementing the different elements.
