ORGANIZATIONAL SETUP
Functional
This traditional structure groups people by specialization (for example, marketing, contracting, accounting, and so on). The project manager has no formal authority over project resources and must rely on the informal power structure and his or her own interpersonal skills to obtain resource commitments from functional managers. Conflicts tend to develop over the relative priorities of various projects competing for limited resources.
Weak Matrix
The matrix organization maintains vertical functional lines of authority while establishing a relatively permanent horizontal structure containing the managers for various projects. The project managers interact with all functional units supporting their projects. In a weak matrix, the balance of power leans toward the functional manager rather than the project manager. That is, workers’ administrative relationships, physical proximity, and relative time expenditures favor the functional manager.
Strong Matrix
The strong matrix is the same as the weak matrix except that the balance of power favors the project manager rather than the functional manager. The project manager has medium to high formal authority.
Projectized
In a projectized organization, a separate, vertical structure is established for each project. Personnel are assigned to particular projects on a full-time basis. The project manager has total authority over the project, subject only to the time, cost, and performance constraints specified in the project targets.
These are the functional organizations; project expeditor, which is little more than a functionary who helps support the concept of project management but not really the practice; the project coordinator is a step up from that. Then a weak matrix is where you actually have the project manager getting resources from the functional organizations; a strong matrix is where the balance of power is shifted to the project manager. The way you tell whether or not that balance of power has shifted is where the money and the reporting flow from. If all money and reports are generated by the project and are respected as being from the project, then it is a strong matrix. If the functional organizations are seen as generating revenue for the organization rather than the project organizations, then it is a weak matrix. And finally, PMI’s ideal structure: the projectized organization, a place where the project has its own reporting structure within the organization.
