Project Roles and Responsibilities

Understanding who does what in a project is fundamental to effective project management. The CAPM exam tests your knowledge of key project roles, their responsibilities, and how they interact.

The Project Sponsor

The project sponsor is a senior executive who provides financial resources and support for the project. The sponsor is often the person who champions the project at the executive level.

Sponsor Responsibilities

  • Authorize the project and sign the project charter
  • Provide funding and financial resources
  • Remove organizational obstacles that the PM cannot resolve
  • Champion the project to senior management
  • Resolve escalated issues beyond the PM's authority
  • Approve or reject changes (may delegate to a Change Control Board)
  • Accept final deliverables and sign off on project completion

PM Competencies (PMI Talent Triangle)

PMI defines three competency areas for project managers:

CompetencyFocus Areas
Ways of Working (formerly Technical)Predictive, agile, hybrid approaches; tools and techniques
Power Skills (formerly Leadership)Communication, problem-solving, collaboration, critical thinking
Business Acumen (formerly Strategic)Organizational awareness, business knowledge, strategic alignment

The Project Team

The project team includes all people who work on the project. Team composition can vary:

Team TypeDescription
DedicatedFull-time members assigned exclusively to the project
Part-timeMembers splitting time between the project and other work
VirtualTeam members in different locations using technology to collaborate
Cross-functionalMembers from different functional departments
Self-organizingTeams that determine how to accomplish work (common in agile)

The Project Management Office (PMO)

A PMO is an organizational structure that standardizes project governance and facilitates sharing of resources, methodologies, and tools.

PMO Types

TypeAuthority LevelFunction

ControllingModerate controlProvides support AND requires compliance with frameworks, templates, and governance
DirectiveHigh controlDirectly manages projects; assigns project managers; takes full control

Organizational Structures

The organizational structure affects the project manager's authority and resource availability:

StructurePM AuthorityResource AvailabilityPM Role

Weak MatrixLowLowPart-time, coordinator
Balanced MatrixLow to moderateLow to moderateFull-time
Strong MatrixModerate to highModerate to highFull-time
ProjectizedHigh to near-totalHigh to near-totalFull-time

Exam Tip: In functional organizations, the functional manager has the most authority over resources. In projectized organizations, the project manager has the most authority. Matrix organizations fall between these extremes.
