Business Leadership
Who are the project managers? In the past they would have been IT people. Increasingly business people manage "IT" projects. The business may even have a pool of people whose profession is now project manager. They may well be certificated, for example by the Project Management Institute. They will be called upon to manage the organisation's major projects, particularly systems development projects.
All business people who become involved in projects (not just the project managers) receive project management education. However, invite a senior manager to a project management course and he will see the words "management course" and conclude he does not need another one of them! The idea that project management is an additional set of management techniques has to be sold.
The education is not how to use a PC based planning tool or how to do PERT network analysis. It is not training in the bureaucratic impositions of a complex methodology. It is not training in how to pass a project management examination. It is training in how projects are run. It includes an insight into the black art of software development - though the education reveals it isn't such a black art after all, and that business people are quite capable of taking a leadership role in it.
The business, including the HR department, understand that when an individual is managing a project they can have the title "project manager" even though they are not a manager in the organisation. Similarly the title "project director" can be given to an individual who is not a Director.
Business people understand that when they are assigned to work on a project, full time or part time, they are working for the project manager even if the project manager has a lower job grade than them. The project hierarchy takes precedence over company hierarchies and seniorities.
