In this episode, we examine how different types of organizational structures—functional, matrix, and projectized—create distinct environments for projects, affecting everything from authority levels to resource access. We also clarify the roles that operate within these structures, such as the sponsoring organization for strategic oversight, the steering committee for key decision-making, project assurance for quality and compliance, along with the sponsor, project manager, and work package leaders. Understanding the fit between organizational structure and project roles is key to optimizing project alignment, efficiency, and ultimate success.
