How to Write a Brief for a Fractional Executive

Most companies that struggle to find the right fractional executive have the same problem: a vague brief. They know they need help, but they haven't clearly articulated what that help should look like, how long it's needed for, or what success means at the end of the engagement.

Knowing how to write a brief for a fractional executive changes that. A well-constructed brief shortens the time to shortlist, improves match quality, and sets the engagement up to succeed from the first conversation.

This guide walks you through exactly what to include, what to leave out, and how to think about scoping an engagement before you speak to anyone.

What a Fractional Executive Brief Actually Is
‍

Before covering structure, it's worth being precise about the document itself. A brief for a fractional executive engagement is not a job description. It is not a statement of work. It sits somewhere between the two: a focused document that gives a senior, experienced leader enough context to understand the problem, assess whether they can solve it, and ask the right questions in a first conversation.

Job descriptions are designed for employment relationships. They list responsibilities, qualifications, and reporting lines. A fractional brief is outcome-oriented. It describes a business situation, not a role profile.

This distinction matters because the executives you are approaching have typically operated at C-suite level for years. They are assessing you as much as you are assessing them. A document that reads like a standard job ad signals that the hiring team hasn't thought carefully about what fractional work actually involves, which can put off exactly the calibre of person you want.

The brief should be concise. Two to four pages is typically sufficient. If you find yourself writing more than that, you are likely documenting rather than scoping, and the two are different exercises.

Start With the Business Context

The opening section of any strong brief covers the business: what you do, where you are in your growth or transition, and what has changed recently that's driving this hire. This is not a marketing pitch about how exciting the company is. It's an honest orientation that helps a senior executive understand the landscape they'd be walking into.

Cover these elements directly:

→ Industry and business model (two to three sentences, not a mission statement)

→ Current revenue range and team size, or a general indication if exact figures are sensitive

→ Stage of business: early growth, scaling, pre-IPO, post-acquisition, restructuring

→ Recent or upcoming changes: new markets, leadership transitions, funding events, system overhauls

→ Any relevant constraints: geographic complexity, regulatory environment, legacy infrastructure

You don't need to disclose everything at brief stage. But the executive needs enough to know whether this is a context they've operated in before and whether the engagement is genuinely within their experience.

Be honest about challenges. If the business has gone through a difficult period, or if the previous executive left under strained circumstances, say so plainly. Experienced fractional leaders have seen all of it. What they don't want is to discover it three weeks in.

Define the Problem, Not the Solution

This is where most briefs go wrong. Companies often describe what they want someone to do rather than the problem they need solved. These are not the same thing.

A brief that says "we need a Fractional CFO to build our financial reporting function" is describing a task. A brief that says "our board has requested monthly management accounts and we have no internal capability to produce them, and we need to be investor-ready within nine months" is describing a problem. The second version gives an experienced executive the context to design the right approach, not just execute a predefined checklist.

Ask yourself these questions before writing this section:

→ What specific outcome needs to exist at the end of this engagement that doesn't exist now?

→ What is the consequence of this problem not being solved in the next six to twelve months?

→ Is this primarily a build problem, a fix problem, a scaling problem, or a transition problem?

→ Have we tried to solve this before? If so, what happened?

The answers to those questions are the core of your brief. A Fractional CMO assessing a revenue growth brief, or a Fractional CTO reviewing a technology infrastructure scope, will immediately understand whether the engagement suits their experience if the problem is stated clearly.

A Weak Brief and a Strong Brief, Side by Side

The difference between a brief that works and one that stalls is easier to see than to describe. Here are two versions of the same request.

Weak brief

“Seed-stage startup looking for a fractional CMO to help with marketing strategy and growth.”

Strong brief

“We’re a B2B SaaS company, 18 months post-launch, $1.2M ARR, selling into mid-market HR teams. We have an SDR team with no demand generation engine behind it. We need a Fractional CMO who has built pipeline from scratch at a similar stage, ideally with HubSpot and paid LinkedIn experience. Looking for 15 hours a week across four months. Success looks like a repeatable outbound motion and our first two inbound SQLs from content.”

The second version names the stage, the revenue, the buyer, the gap, the tools, the time commitment and the result. It takes around two minutes longer to write, and it removes roughly four weeks of misaligned conversations.

Look at how much work each line is doing. Every detail gives a senior operator something concrete to measure themselves against, which is what allows the right person to self-select in and everyone else to move on quickly. If you are briefing a marketing role specifically, the questions worth asking a Fractional CMO are a useful test of whether your brief already answers them.

Scope, Time Commitment, and Duration

Fractional executives work across multiple clients simultaneously. That is the model working as designed, and it means the brief must be honest about the time commitment expected, because it directly affects how the engagement is structured and priced.

Typical fractional arrangements in our experience run across three broad formats:

→ Project-based: a defined deliverable with a fixed end point, typically two to four months

→ Retainer-based: an ongoing commitment of two to four days per week across six to twelve months

→ Advisory: lighter-touch involvement, typically one to two days per month for strategic input

Specify which model you believe fits the problem. If you're uncertain, say so, and offer your best thinking rather than leaving it entirely open. An engagement with no defined structure is harder to price, harder to resource, and harder to close.

Be specific about where the executive needs to be physically. Many fractional executives work remotely, and in fact 57% of fractional executives globally work primarily remotely according to industry research. If you need on-site presence in Melbourne, London, or Austin, that's relevant information that should be in the brief.

Include the anticipated start date, even if it's approximate. A fractional executive with multiple clients manages a forward calendar carefully. "As soon as possible" is not a usable answer.

Authority, Reporting, and Team Structure

This section is often left out entirely, which creates significant problems once an engagement begins. A fractional executive needs to understand the authority structure they would operate within: who they report to, whether they have decision-making authority or an advisory mandate, and what team or resources they would have access to.

For roles like a Fractional COO or Fractional CRO, the operating structure is especially important. These roles typically need to work across functional teams and may need to make or influence resourcing decisions quickly.

Address the following in your brief:

→ Who the fractional executive reports to directly (founder, CEO, board)

→ Whether they will have a mandate to make decisions or a mandate to advise and recommend

→ What internal team, if any, they will manage or collaborate with

→ Whether there is a full-time executive in place in an adjacent or equivalent role

→ Any internal politics or sensitivities the executive should be aware of

The last point is one that companies routinely omit. If there is an existing team member who applied for the role, or a co-founder who has reservations about external help, that is material information. A good fractional leader can manage these dynamics, but only if they know about them before they start.

Success Metrics and Handover

A brief without defined success criteria is a brief without accountability. Before you finish writing, specify what success looks like at the three-month mark and at the end of the engagement.

These don't need to be overly rigid. The exact metrics may shift as the engagement progresses, and experienced executives expect that. But the brief should demonstrate that you've thought about what progress looks like in concrete terms.

Examples of well-defined success criteria by role:

→ Fractional CFO: board-ready monthly accounts delivered by month two, financial model built and validated by month four, fundraising documentation complete by month seven

→ Fractional CMO: brand positioning finalised, paid acquisition channels tested and benchmarked, marketing hire recruited and onboarded

→ Fractional CTO: technical architecture reviewed and documented, engineering hiring plan agreed, key technical debt addressed

Also address handover. What happens at the end of the engagement? Is there a full-time hire planned? Will knowledge transfer to an existing team member? Understanding the exit plan helps the executive structure their work from the start rather than leaving institutional knowledge to evaporate when the engagement closes.

Budget: Address It Directly

Many companies treat budget as a late-stage negotiation. In fractional hiring, this approach consistently delays the process and, in our experience, often leads to mismatched shortlists.

Fractional executive costs vary by role, seniority, and time commitment. In Australia, for example, a Fractional CFO typically runs between $7,000 and $15,000 per month on a retainer basis (SEEK, 2026), while a Fractional CMO typically ranges from $10,000 to $18,000 per month (Glassdoor AU, 2025). In the US, comparable roles often run between $8,000 and $22,000 per month depending on scope (Built In, 2026).

Include a budget range in your brief, not a fixed figure. A range signals that you have thought about this seriously, while leaving room for a conversation based on scope. If budget is genuinely constrained, say so clearly, because it will affect what kind of engagement is realistic and what the fractional executive can reasonably deliver within that constraint.

Being transparent about budget early also signals maturity as a client. Experienced fractional executives have worked with companies at all stages and are generally comfortable with honest conversations about money. What they find frustrating is discovering that the budget was always fixed and the "negotiation" was never real.

Say What You Are Not Looking For

This line is underused, and it works harder than almost anything else in the document. One sentence ruling out the wrong profile can save you an entire round of conversations.

Examples that earn their place:

→ “We already have a growth agency handling paid, so vendor management sits outside this engagement.”

→ “This is a hands-on build. A purely advisory mandate will not suit.”

→ “The tech stack stays as it is. What needs to change is the process around it.”

→ “We have already had two consultants deliver strategy documents. We need execution against one of them.”

Each of those does two jobs. It filters out profiles that would waste a call, and it signals that you have thought carefully about the shape of the work. That confidence attracts stronger candidates on its own, because experienced operators read a clear exclusion as evidence that the rest of the brief has been considered just as carefully.

Exclude profiles rather than people. “No agencies” is useful and specific. “No one who has only worked in enterprise” is a judgement better tested in conversation, since some of the strongest fractional operators have moved between company sizes deliberately.

Before You Submit Your Brief

When the brief is drafted, read it once from the perspective of a senior executive who has never met your company. Ask whether that person would have enough context to understand the problem, assess their fit, and prepare for a first conversation.

If the answer is no, the brief needs more work. If it reads as a task list rather than a problem statement, revisit the second section. If the success criteria are vague, tighten them. If the authority structure is missing, add it.

A strong brief does not need to be exhaustive. It needs to be clear, honest, and specific enough to attract the right person and give them confidence that this engagement has been thought through.

Once the brief is out and a shortlist comes back, the interview is the next thing to get right. Our guide on how to interview a fractional executive covers the two-stage format, who should be in the room, what to send candidates ahead of the first call, and the scorecard for rating candidates consistently across a panel.

Frequently Asked Questions

How long should a fractional executive brief be?

Two to four pages is typically sufficient. Longer briefs tend to document rather than scope, which makes them harder to act on. Focus on the problem, the outcome, the time commitment, and the commercial parameters. A well-structured two-page brief consistently outperforms a ten-page role description.

Do I need to know the exact role before writing a brief?

Not always. If you know the outcome you need but aren't certain whether it requires a Fractional COO or a Fractional CRO, write to the problem and let the matching process guide the role. Fractionus can help you assess the right fit based on what you've described. You can also use ASK Fractionus to get a steer before committing to a brief.

Should I include confidential financial information in the brief?

Not necessarily at this stage. A general revenue range and business stage is usually sufficient to allow initial matching. Detailed financials, projections, and sensitive data can be shared later under a non-disclosure agreement once there is mutual interest from both sides.

What's the difference between a fractional executive brief and a job description?

A job description is designed for an employment relationship. It lists responsibilities, qualifications, and reporting lines in a standardised format. A fractional brief is outcome-oriented and problem-led. It works as a diagnostic tool that helps a senior executive assess whether they can solve your specific problem within your specific context.

Can you show me an example of a strong brief?

There is a worked comparison above of a weak and a strong version of the same Fractional CMO brief. The pattern holds across functions: name the stage, the specific gap, the background you need, the time commitment, and the result you expect within 90 days. Swap the function-specific detail and the same structure carries a Fractional CFO or Fractional COO brief just as well.

What if we don't know our budget yet?

Provide a range based on what you know. If budget is genuinely unresolved, it's worth reviewing the cost guidance for your market before submitting a brief. Engaging a fractional executive without a budget conversation is unlikely to result in a productive first meeting, and it often delays shortlisting.

Can the brief evolve once the engagement starts?

Yes, and it often does. A brief is a starting point, not a contract. Experienced fractional executives typically conduct a discovery period in the first two to four weeks where they validate or challenge the original framing. What matters is that the brief is honest and specific enough to begin that process productively.

How does Fractionus use the brief to match candidates?

The brief is reviewed by the Fractionus team against a vetted pool of fractional executives, only 3% of applicants are accepted onto the platform. The matching process considers industry context, functional expertise, stage of business, and time commitment. A shortlist is typically delivered within two to five business days of receiving a complete brief.

What if we've never hired a fractional executive before?

That's common. Many companies come to fractional hiring having only ever hired full-time employees. If you'd like to understand the how it works process before writing a brief, that's a good starting point. The model is straightforward once the core principles are clear, and the brief-writing process itself often clarifies thinking about what the business actually needs.
