In which organizational structure would the project manager have most authority?

According to the PMBOK® Guide and the PMI organizational theory, the level of authority a project manager possesses is directly tied to the organizational structure. In a Matrix environment, authority is shared between functional managers and project managers, but the balance shifts depending on the specific type of matrix.

Matrix-strong: In this structure, the project manager has a high to almost total level of authority. They often have a full-time staff and a dedicated project administrative staff. The power dynamic favors the project manager over the functional manager, and the project manager often controls the project budget.

Matrix-balanced: The project manager and functional manager share power and authority equally. This can often lead to conflicts regarding resource priority.

Matrix-weak: The project manager ' s role is more akin to a project coordinator or expeditor. They have very limited authority and act more as a facilitator than a manager with decision-making power.

Organic or Simple: Typically found in small businesses or startups, authority is very flexible or resides almost entirely with the owner/founder. The " Project Manager " role is often part-time or non-existent in a formal capacity.

In the hierarchy of authority defined by PMI, the only structure providing more authority than a Strong Matrix would be a Project-Oriented (Projectized) organization, where the project manager has total control. Since " Project-Oriented " is not an option here, Matrix-strong is the correct choice as it offers the highest level of authority among the listed selections.
