In many organizations, especially matrix or functional structures, a project manager (PM) is held responsible for results but does not directly control the people doing the work.
This creates the classic tension between accountability and authority.
1. Accountability
Accountability means being ultimately responsible for the outcome of something.
For a project manager this usually includes:
- Delivering the project on time
- Staying within budget
- Meeting scope and quality requirements
- Managing risks and stakeholders
Even if the PM doesn’t directly perform the work, they are still judged on the final result.
2. Authority
Authority means the formal power to make decisions, assign work, and control resources.
Examples of authority:
- Hiring or firing team members
- Directly assigning tasks
- Performance evaluations
- Approving budgets
In many companies, these powers belong to functional managers, not the PM.
3. Why the Gap Exists
The gap appears in structures such as matrix organizations, studied in the field of Project Management.
Typical setup:
| Role | Responsibility | Authority |
| Project Manager | Deliver project | Limited authority |
| Functional Manager | Manage people | Full authority over staff |
So, the PM must coordinate work without owning the team.
4. How Project Managers Actually Get Work Done
Since formal authority is limited, effective PMs rely on influence rather than command:
Key tools:
- Stakeholder alignment
- Clear communication
- Negotiation with functional managers
- Building trust and credibility
- Escalation when necessary
This is often called “leading without authority.”
5. Risks of This Model
When accountability ≠ authority, problems can arise:
- Delays because PM cannot reassign people
- Resource conflicts between projects
- Difficulty enforcing deadlines
- Blame placed on PM for things outside their control
6. How Mature Organizations Address It
Better organizations balance the gap by:
- Giving PMs budget control
- Using projectized teams
- Establishing clear escalation paths
- Ensuring executive sponsorship
Some structures even give PMs temporary authority over team members during the project lifecycle.
Final Word
A project manager’s power often comes less from hierarchy and more from influence, coordination, and leadership.
