The document discusses different organizational structures that can influence project management. It describes functional, projectized, and matrix structures. In a functional structure, departments are grouped by specialty and execute their own projects, but project managers have little authority. A projectized structure dedicates resources solely to projects and gives project managers full control. Matrix structures combine functional and project aspects, and can be strong (project-dominant), weak (functional-dominant), or balanced. The document emphasizes that understanding an organization's structure helps a project manager effectively navigate authority, communication, and resource allocation.
