A Model Born Out of Necessity
Most SMEs reach a point where they need proper project management capability — but can't justify, or can't afford, a senior full-time PM. A good Programme Manager or Head of Delivery costs £70,000–£100,000 per year in the UK. For a business turning over £5m–£20m, that's a significant overhead for a capability they might only need intensively during specific periods of growth or transformation.
The fractional model solves this problem. Instead of hiring one senior PM full-time, you engage a highly experienced professional for a defined portion of their working week — typically one to three days — at a fraction of the cost. You get access to senior-level thinking and delivery experience without the full salary, benefits, and employment overhead.
It's the same model that's made fractional CFOs and fractional CMOs increasingly common in the SME space. Project management is simply the next discipline where the model makes obvious sense.
How a Fractional PM Engagement Actually Works
Engagements vary, but a typical fractional PM arrangement at The PM Office works as follows. An initial discovery conversation establishes what the business is trying to achieve — whether that's delivering a specific programme of work, building project management capability, or getting visibility across a portfolio of initiatives.
From there, we agree on a scope and a weekly or monthly commitment: the number of days per week, which meetings they'll attend, what they'll report on, and who they'll work alongside. The engagement is then reviewed monthly and adjusted as the business's needs evolve.
Importantly, a good fractional PM is embedded, not remote. They attend your team meetings, work with your project leads, understand your politics and your constraints. The 'fractional' part refers to the proportion of their time — not their level of engagement or commitment to your outcomes.
What Fractional PMs Are Good For
- Portfolio oversight — Getting visibility across multiple concurrent projects and ensuring prioritisation decisions are being made rationally.
- Transformation programmes — Providing senior delivery leadership for a system implementation, restructure, or growth initiative with a defined endpoint.
- PMO setup and mentoring — Establishing the right frameworks and tooling, then coaching internal PMs to maintain them independently.
- Bridge roles — Covering a maternity leave, a sudden departure, or the gap between hiring cycles without losing momentum.
- Board-level reporting — Producing the programme governance and portfolio reporting that leadership needs to make confident decisions.
What Fractional PMs Are Not
It's worth being clear about the limits of the model. A fractional PM is not a project coordinator who will manage every task and chase every action. They are a senior strategic resource — their value is in decision-making, problem-solving, governance, and the raising of issues before they become crises.
For hands-on day-to-day task management across multiple workstreams, you may also need project coordinator support alongside the fractional PM. This combination — senior oversight plus operational coordination — is often the most effective and cost-efficient structure for an SME in a period of active delivery.
The fractional model works best when the business treats the fractional PM as a genuine part of the leadership team, not a supplier to be managed at arm's length. The more access and context they have, the more value they deliver.
Is It Right for Your Business?
The fractional model tends to suit businesses in one of the following situations: a growth-stage company that has outgrown ad-hoc delivery but isn't yet ready for a full-time PMO head; an established SME facing a major programme of change; or a business that has had delivery problems and needs senior, credible leadership to stabilise things quickly.
It's less suited to businesses that need constant, intensive delivery coverage across dozens of simultaneous projects — at that point, a full-time resource is likely more cost-effective. And it's less suited to businesses where the senior leadership team won't engage with or support a part-time resource.
If you're trying to work out whether the model fits, the best thing to do is have an honest conversation about it. Our Fractional PM service page covers how we structure engagements, or you can book a free 30-minute discovery call to talk through your specific situation.
