A PMO may be set up to struggle before it even begins operating. PMO responsibilities may be defined in the establishment charter, yet leadership expects the office to guarantee project delivery, secure resources from departments, and accelerate approvals beyond its authority. When a project falls behind, the PMO takes the blame for decisions it could not make. The problem begins with a mismatch between expectations and authority. Understanding that gap is essential to defining a realistic mandate and measuring the value the office actually delivers.
PMO responsibilities depend on why the office was established and the authority it has been given. Some offices support project managers, others enforce governance standards and oversee portfolios, while directive PMOs may assume direct responsibility for managing projects.
Common PMO functions include:
The Project Management Institute’s guidance on selecting the right PMO model emphasizes aligning PMO responsibilities with institutional needs. Different models provide different levels of support, control, and direct management. A standard list of duties should therefore inform the mandate, not automatically define it.
For more on governance and decision-making, read Synexcell’s The Project Management Office (PMO) and Its Impact on Improving Project Governance.
Leadership may have reasonable expectations of a PMO, but meeting them sometimes depends on resources or decisions that sit outside its authority.
Consider a hypothetical case: the PMO identifies a delay in a digital project because the technology team is committed to other projects. It reports the schedule impact and presents options for addressing the shortage.
If management does not resolve the resource allocation, the PMO should not be held responsible for that decision. Its performance should be assessed through the accuracy of its monitoring, the quality of its recommendations, and the timeliness of escalation. Resource allocation remains with the authorized decision-maker.
How Do Unrealistic Expectations Affect PMO Success?
Unrealistic expectations create accountability without matching authority. Leadership then judges the PMO against outcomes that depend partly on decisions made elsewhere. Over time, project teams may lose confidence in the office, particularly when they see it requesting more information without helping remove delivery constraints.
The consequences generally appear in three related areas:
A PMI analysis of why PMOs fall short of their potential identifies unclear purpose, insufficient authority, and poor stakeholder expectation management among the challenges that can weaken their effectiveness.
These findings do not establish a universal failure rate. They show why clarity at establishment matters.
The distinction is critical: identifying a problem, recommending action, and escalating it are different responsibilities from executing the solution or approving the decision. Evaluating all of them against the same outcome obscures where intervention is needed.
Leadership must establish a clear mandate and respect it when allocating work and making decisions. If the PMO is expected to manage part of project delivery, that arrangement should be explicit from the outset, including the work it owns, who authorizes intervention, and the resources available to carry it out.
To set realistic expectations, leadership should agree on four essentials:
These agreements should be recorded in an approved charter, with clear project management office roles and responsibilities supported by a PMO roles and responsibilities matrix, such as RACI.
The following examples show how accountability may be allocated:
| Situation | PMO Responsibilities, Subject to Their Mandates | Delivery or Decision Owner |
| Schedule variance | Validate the data, assess the impact, and escalate | The project manager develops the response; the authorized decision-maker approves matters beyond delegated limits |
| Two projects competing for a critical resource | Explain the conflict, available options, and implications | The resource-owning manager or delegated committee decides allocation |
| Major scope change | Assess the impact and apply change-control requirements | The authorized approver accepts or rejects the change |
| New project proposal | Review information and prioritization criteria | The investment committee or other authorized decision-maker approves initiation |
A directive PMO may also carry direct project management responsibilities. What matters is documenting the arrangement in the approved operating model rather than assuming one allocation of duties applies everywhere.

A PMO performs best when its services address specific needs, stakeholders understand what to expect, and the information it provides leads to decisions. It should begin with a manageable scope and expand when there is evidence that its services are useful.
Maturity assessment can help identify weaknesses in project management practices and prioritize improvements to the PMO’s capabilities. For more on this approach, read Synexcell’s P3M3 Framework for Measuring and Improving Organizational Management Maturity.
The value of a PMO becomes clearer when its mandate reflects institutional needs and every major responsibility is supported by appropriate authority, resources, and performance measures. Holding the office accountable for decisions beyond its control can undermine trust before it has a fair opportunity to demonstrate results. Synexcell Management Consultancy supports institutions through PPPM Design and Delivery, including PMO establishment, operating model design, governance, methodologies, performance monitoring, and capability development.
Give your PMO a mandate it can deliver. Get in touch with Synexcell’s experts to redefine the right responsibilities, establish clear decision authority, and build an office whose contribution can be measured from the start.
Team size depends on the number and complexity of projects, the services required, oversight needs, supporting systems, and whether the PMO provides guidance or directly manages projects.
A central PMO supports a wider portfolio and may oversee governance across an institution. A project-specific or program-specific PMO serves a narrower mandate and may operate for a limited period.
A PMO responsibilities manager includes sound knowledge of project management, governance, and performance reporting, along with the ability to analyze delivery issues, coordinate across departments, and work effectively with decision-makers.
Start by understanding the objections and assessing whether the requirements add value. Clarify the agreed authority, simplify unnecessary steps, and provide training where new practices are needed.
