Fractional COO / CTrO · UK-wide
Senior operational leadership for growing businesses.
Growth creates complexity.
Processes that worked at £3m can start causing problems at £10m. More decisions come back to the CEO, systems become harder to manage and the leadership team spends more time dealing with day-to-day operational issues.
I work with CEOs, MDs and leadership teams that need experienced operational and transformation leadership, but do not necessarily need a full-time COO or Chief Transformation Officer.
Typically this means joining the business for a set number of days each month and taking responsibility for the areas that need senior ownership.
From £900 a day, or retainers from £3,250 a month. Plus VAT.

When it is useful
When Fractional COO / CTrO support makes sense
I typically work with businesses between £10m and £100m turnover and fifty to five hundred people, including founder-led, private-equity backed and family-owned companies. I am also comfortable in regulated environments.
Common issues include processes that have not kept up with growth, too many systems, inconsistent data, unclear ownership and a leadership team spending too much time on day-to-day operational problems.
My role is to work out which issues genuinely need senior attention, set the priorities and help the business deliver them.
Typical reasons
- Too many decisions still depend on the founder or CEO
- A business case is approved and nobody senior can own it
- The COO has left and the business needs experienced cover during the search
- Pre-deal diligence or post-deal integration is imminent
What I can own
What I can take responsibility for
A full fractional role can cover all four areas. Some engagements start with one or two priorities and expand if the business needs more.
How major change gets delivered
How I deliver major change
Map. Automate. Scale. is the overall M.A.S Works method. For larger transformation work, I use a more detailed delivery approach underneath it: define the problem, design the solution, deliver the change and then embed it.
01
Define
Be clear about the problem, the value and the outcome
- Clear scope and problem definition
- A quantified case and the outcome targets against it
- Success measures at twelve, twenty-four and thirty-six months
- Stakeholder map and the governance that will actually be used
Output: mandate, business case and success criteria
02
Design
Design a practical solution and the team needed to deliver it
- Solution and operating model designed for the business
- Team design across the internal team and any external partners
- Technology and vendor selection, budget approval, procurement gates
- Risk register created from day one, with clear controls and owners
Output: solution design, mobilised team and approved budget
03
Deliver
Take responsibility for delivery and the agreed outcome
- Weekly delivery reviews with clear ownership across every workstream
- Active risk and issue management, with problems dealt with early
- Executive and board-level stakeholder management
- Change management built into the delivery plan
Output: a working solution that has been adopted and measured
04
Drive
Embed the new way of working and track the value
- Handover to business as usual with a clear run cost
- Continuous improvement cycle and value tracking
- Close support after launch until the change is working reliably
- Knowledge transfer, so the capability stays after I go
Output: the new way of working embedded and the results measured
Pricing and engagement
Day rate or monthly retainer
Defined projects can start on a day rate. Ongoing leadership usually moves to a monthly retainer, reviewed quarterly so the number of days can move up or down.
Indicative pricing, all excluding VAT, confirmed against scope before anything is agreed.
