Resources for a project report to a project manager and a functional manager. The organizational structure is:

A Matrix organizational structure is characterized by dual reporting relationships, where team members report to both a project manager for project-specific work and a functional manager for administrative and disciplinary matters. This structure balances functional expertise with project focus, allowing for shared resources across multiple projects.

An Ad hoc organizational structure refers to a temporary, flexible structure formed for a specific, often short-term purpose, and does not typically involve formal dual reporting to project and functional managers.

A Functional organizational structure groups employees by specialized departments where resources report solely to a functional manager, with project work often managed within functional silos.

A Projectized organizational structure organizes teams around specific projects, with project team members reporting exclusively to the project manager, who has full authority over the project and its resources.
