Fractional vs interim executive: which do you need?

Short answer: a fractional executive works part-time, usually one to three days a week, on an ongoing basis, and owns outcomes. An interim executive works full-time for a fixed term, typically three to eighteen months, to cover a gap or a critical period. A consultant advises, but doesn’t own the outcome.

I offer both fractional and interim roles, so I have no reason to push you towards either. In my experience the choice depends on the problem, not the budget:

• A gap in the seat calls for interim.
• A gap in capability calls for fractional.
• A gap in information calls for a diagnostic or a consultant.

Get that diagnosis right and the rest of the decision usually follows.

Fractional vs interim vs consultant at a glance

Dimension	Fractional	Interim	Consultant
Time commitment	One to three days a week	Full-time	Scoped to the project
Typical length	6–12 months, sometimes longer	3–18 months	Weeks to a few months
Accountability	Owns outcomes, the team and the numbers in a defined C-suite role	Owns the role in full, including the day-to-day running of it	Advises and recommends; you own the outcome
Who it suits	Growing businesses with a capability gap but not enough work for a full-time hire	Businesses with an empty seat, a transformation or a critical period	Businesses that need an independent view, or a problem defined
Typical cost in Australia	Roughly A$7,000–A$18,000 a month in the market; mine start from A$12,000 + GST a month	Quoted on scope; full-time, so well above a fractional seat	A fixed fee or day rate; my diagnostic sprint starts from A$15,000 + GST
How it ends	The team grows into the role, a permanent hire takes over, or it steps down to advisory	A permanent leader is appointed and handed over to, or the program is delivered	Findings and recommendations are handed over

When fractional is the right call

Fractional works best when the business needs C-suite experience in a function, but not five days a week of it. That’s usually true when:

• You’re growing, and a function needs experience the team doesn’t have yet
• The CEO is carrying a second role, often sales or operations, on top of their own
• There’s one to three days a week of senior work, not a full-time load
• You want to build the capability before committing to a permanent hire

A good example of fractional-shaped work is the launch problem I took on at a global consumer brand. Every new product launch meant coordinating eight internal teams, four regions and fourteen external agencies, and the know-how lived in people’s heads. The fix was to document the sequence and turn it into a single automated workflow: one intake form now triggers 450 tasks.

That pattern is common in mid-market businesses. The problem needs senior ownership and steady attention over months, but once the design is settled, it doesn’t need a full-time executive to keep it running. That’s where a fractional COO, fractional CRO or fractional Chief AI Officer earns their keep.

When interim is the right call

Interim is for when part-time attention won’t do. The common triggers are:

• A sudden departure. Your CRO or COO leaves at short notice, and the seat can’t sit empty for the three-to-six-month search a permanent hire usually takes.
• A transformation that needs full-time ownership. A restructure, a platform migration or a turnaround needs someone in the building every day, making decisions and clearing blockers.
• Pre-IPO or post-acquisition integration. Fixed deadlines, high scrutiny and no second attempt.

The IPO point is one I know well. I developed and delivered the go-to-market strategy for IPO campaigns for an ASX-listed investment management group, with fixed timelines and many external suppliers to manage. One campaign raised more than A$300M. That was a consulting role, but the shape of the work is exactly what interim exists for: a fixed window, high stakes and no room for a slow start. I’ve also stepped in as acting head of digital for a global health and wellness brand, which is interim by another name.

I’m based in Melbourne, and for longer interim engagements I’m open to travel and to relocating. If the right person for a critical period is in another city or country, that shouldn’t be what stops you.

When neither: start with a diagnostic

Sometimes the honest answer is that you don’t need an executive in the seat yet. You need to know what the problem is.

If growth has stalled and nobody can say whether it’s the product, pricing, channels or execution, hiring a fractional or interim executive into that uncertainty is an expensive way to guess. A consultant or a diagnostic is the better first step.

My diagnostic sprint is about two weeks of senior time and ends with board-ready findings and a 90-day plan, from A$15,000 + GST. Sometimes it shows you need a fractional seat. Sometimes it shows you need interim cover. Sometimes it shows your team can fix it with a clear plan, and that’s a useful answer too.

The difference from a fractional role is ownership. Consultants usually advise and hand over a report. That’s fine if you have the people to execute it. If you don’t, the report tends to sit in a drawer.

Moving between models

These models aren’t fixed. A good engagement can change shape as the business does.

Fractional to interim

If a leader leaves, or a program suddenly needs full-time ownership, a fractional executive can step up to interim. The advantage is speed: they already know the business, the team and the numbers, so there’s no ramp-up at the moment you can least afford one.

Interim to fractional

Once the crisis has passed or the transformation is in place, an interim executive can step down to one or two days a week while a permanent leader settles in, or to an advisory retainer from A$5,000 + GST a month. That keeps continuity without paying for full-time cover you no longer need.

Consultant to owner

At an ASX-listed technology company, I was first engaged as a consultant to build a global go-to-market strategy. The company then created the role of Chief Revenue & Marketing Officer, and I took it on, owning a global P&L of around A$15M. Building the strategy and then owning its execution meant the plan had to survive contact with reality.

To a permanent hire

The aim of any fractional or interim role should be that the business no longer needs me in that seat. Either the team grows into it, or I help you recruit and onboard a full-time executive.

I plan for that from the start. By the time a permanent leader arrives, the priorities, measures and operating rhythm should already be written down and working, so they take over a running function rather than a blank page.

Questions to ask before you choose

Before you decide on fractional, interim or a consultant, work through these with your leadership team or board:

1. Is the seat empty, or is the capability missing? An empty seat points to interim. Missing capability points to fractional.
2. How many days a week of senior work is there, really? Be honest. One or two days doesn’t justify a full-time hire.
3. Do we know what the problem is? If not, diagnose it first.
4. Is there a fixed deadline? A raise, IPO, exit or integration changes the calculation.
5. Who will own the outcome? If the answer is “the consultant”, you need an executive, not a consultant.
6. What does the end look like? A permanent hire, a more capable team or a finished program. Decide before you start.
