Short answer: in the first 90 days a fractional executive should diagnose the business (days 1–30), agree priorities and measures with the leadership team (days 31–60), and then run the work and show a first result (days 61–90). By day 90 you should have a written diagnosis, a short list of measured priorities and at least one result.
“Fractional” can sound like “part-time adviser”. It isn’t, or at least it shouldn’t be. A fractional executive holds a real seat at the leadership table, owns outcomes and is accountable for them. The difference is that you get that seniority for one to three days a week instead of five, and for as long as the job needs rather than indefinitely.
So what does that look like in practice? Here’s how I approach the first 90 days.
Days 1–30: Diagnose before you prescribe
The temptation in any new role is to start fixing things straight away. Resist it. The first month is about understanding what’s really going on, which is rarely what the brief says.
In the first 30 days I:
- Meet the people who do the work, not just the leadership team. The sales rep, the operations coordinator and the agency account manager usually know exactly where things break.
- Follow the money and the time. Where is revenue coming from, where is it leaking, and where are people spending hours on things a system should do?
- Look at the data you already have, even if it’s messy. Messy data still tells you a lot.
- Write it down. The output is a short, board-ready diagnosis: what’s working, what isn’t, and the three to five things that matter most.
This is the same work as my two-week diagnostic sprint, just embedded in a longer engagement.
Days 31–60: Agree the plan and the measures
A diagnosis is only useful if the leadership team agrees with it. Month two is about turning findings into a plan everyone signs up to.
That means:
- Choosing priorities. Not everything in the diagnosis gets fixed now. We pick what will move the numbers fastest.
- Defining success. Every priority gets a measure and a date. If we can’t measure it, we probably don’t understand it yet.
- Setting the operating rhythm. A weekly leadership check-in, a monthly view for the board, and clear owners for each workstream.
- Making early, visible wins. Something should be measurably better by day 60, even if it’s small. It builds trust and momentum.
Days 61–90: Embed and deliver
By the third month I’m running things, not advising on them. That might mean owning the go-to-market plan as fractional CRO, running the operating cadence as fractional COO, or getting the first AI workflow into production as fractional Chief AI Officer.
The goal by day 90 is that the business is running differently, the team owns the new way of working, and the board can see progress in the numbers.
What a CEO should expect to see
If you engage a fractional executive, by the end of the first 90 days you should have:
- A clear, written diagnosis you agree with
- A short list of priorities with measures and owners
- At least one result you can point to
- A team that’s more capable than it was, not more dependent
That last point matters. A good fractional executive builds capability as they go, so that when the engagement ends, or the role becomes a full-time hire, the business is stronger for it.
If you’re weighing up a full-time hire against a fractional one, the cost calculator puts numbers on it, and fractional vs interim covers the other option. Or book a 30-minute call and I’ll talk it through.
