Project Board: Definition, Roles and Decision Rights
A project board is the body accountable for a project, holding authority the project manager does not: stage approval, funding, tolerance setting and closure. In PRINCE2-derived methods it represents three interests — business, user and supplier — through the executive, senior user and senior supplier roles. In general use it is interchangeable with steering committee.
The three interests
The distinguishing feature of a project board, as opposed to an ad hoc committee, is that its composition is derived from interests rather than from org chart seniority. Each seat exists because someone has to speak for a distinct concern.
| Role | Interest represented | Answerable for |
|---|---|---|
| Executive | Business | The investment holding together: value for money, continued justification |
| Senior user | User | The outputs being usable and the benefits being achievable by the receiving function |
| Senior supplier | Supplier | The delivery capability, technical integrity and resourcing to build what is asked for |
| Project manager | None | Reporting into the board, escalating beyond tolerance, executing what is approved |
| Project assurance | Independent | Checking the reporting the board relies on, on behalf of each interest |
How it is used
A project board works to stage boundaries rather than only to a calendar. At the end of each stage the project manager presents the position and the plan for the next stage; the board approves continuation, requests changes, or stops the project. Between boundaries the board delegates to the project manager within agreed tolerances on time, cost, scope, quality, risk and benefit. As long as delivery stays inside those tolerances, the board receives periodic reports and does not intervene. When a tolerance is forecast to be breached, an exception report goes up and the board decides.
That tolerance mechanism is the practical difference between a board and a meeting. It defines in advance who decides what, which is the same problem tackled in programme governance for multi-project structures. It also shapes what the project manager can settle alone — a boundary explored in project manager vs programme manager.
The pack a board reads is close to a steering committee pack: position against plan, forecast, escalations, and the decisions requested. The SteerCo deck covers that ground, and a board that spends its time on cross-team commitments will get more use out of the decision log and dependency matrix, which keeps each decision with its date, owner and the dependency it unblocked.
Where it goes wrong
- Roles filled by title rather than interest. A senior user seat given to someone with no authority over the receiving function produces acceptance decisions nobody honours.
- Tolerances never set. Without them, everything is either escalated or nothing is, and the board finds out about a breach after the fact.
- One person holding two interests. Where the executive is also the senior supplier, the check that the structure exists to provide is gone.
- Stage boundaries treated as formalities. A boundary that always approves continuation is a diary event, not a control point.
- Board and delivery reporting diverging. Where board papers are written independently of the trackers, the forecast presented and the forecast held by the team differ.
Related terms
Steering committee — the general-purpose equivalent, usually without formalised interest roles. Exception report — what the project manager raises when a tolerance is forecast to be breached. Highlight report — the routine report the board receives inside tolerance. Change control board — a separate body that handles scope change where the volume justifies it. Project charter — the document that, in non-PRINCE2 environments, establishes the authority the board holds.
Questions
Is a project board the same as a steering committee?
Functionally they occupy the same position. Project board is the PRINCE2 term with defined roles and tolerance mechanics; steering committee is the general term and its composition varies by organisation.
Who chairs a project board?
The executive chairs. The executive is the single point of accountability for the project's continued business justification and takes the decision if the board cannot reach agreement.
What are project board tolerances?
Agreed limits on time, cost, scope, quality, risk and benefit within which the project manager may proceed without referring upward. A forecast breach triggers an exception report.
Can a project have both a project board and a steering committee?
Occasionally, in large programmes where a project board handles one workstream and a programme-level committee handles investment across all of them. Where both exist, the split of decision rights has to be written down or items bounce between them.
