As you know, many factors influence the process of developing a project management structure such as projects frequency, the level of specialization, and the need for coordination.
In this respect, a project has three organization structures available for design and all are defined by the level of organizational authority given to the project manager:
Programmatic based: in which project managers have authority only within the program focus or area. The programmatic focus refers to a traditional structure in which program sector managers have formal authority over most resources. It is only suitable for projects within one program sector.
Matrix based: in which the project manager shares responsibility with other program unit managers. Matrix based project organizations allow program units to focus on their specific technical competencies and allow projects to be staffed with specialists from throughout the organization.
Project based: in which project managers have total authority. The project manager in this structure has total authority over the project and can acquire resources needed to accomplish project objectives from within or outside the parent organization, subject only to the scope, quality, and budget constraints identified in the project. This kind of structure is adopted in organizations that already use Management by projects.
