Executive Transition Coaching: The First 90 Days in a Bigger Seat

By Andreas Pettersson, Founder, Leaders ADAPT

It's week three in the new seat. Your calendar is full of meetings you didn't set. Two of your direct reports wanted your job. The board chair has already asked for "your plan," and you haven't finished learning what the last person left behind.

Here's the problem. You were promoted for what you did in the old role. The new role judges you on something else, and nobody tells you what, or when the judging starts.

That's the job of executive transition coaching: to get you through the first 90 days in a bigger seat before the story about you gets written without you. I've made these jumps myself, from consultant to product manager, and later to CEO at 37. There's one diagnostic I run in the first session with every leader in a new role. I'll give it to you below.

What is executive transition coaching?

A leadership transition is a change in role, scope, or reporting line that changes what a leader is accountable for and who judges the result.

Executive transition coaching supports a leader through one specific transition, for a fixed period. It differs from general coaching for leadership development, which builds skills over time without a single deadline. It also differs from company onboarding, which teaches systems, policies, and people. Transition coaching works on the leader's decisions, relationships, and credibility during the window when first impressions set.

Most practitioners frame this window as the first 90 days. The frame was popularized by Michael Watkins' book The First 90 Days (Harvard Business Review Press, 2003, updated 2013).

Let me be direct about what that means in practice. You don't have a knowledge problem in a new seat. You have an authority problem. The rest of this post is about that.

The five leadership transitions and what each one changes

Each step up changes a different thing. The table summarizes the five transitions this cluster covers, with a common failure point at each.

If you're moving into the C-suite, there's also a c-suite executive transition plan you can work through on your own.

The last row is where executive coaching change management work overlaps with transition work. When a company grows fast, the leaders don't change seats, but the seats change under them. I call the plateau that follows the Valley of Death, and I cover it in the post on leading through change as a CEO.

What breaks in the first 90 days, and when

Nothing breaks on day one. Things break on a schedule. Here's the schedule I see, and the rules I give clients at each stage.

Days 1 to 30: authority before answers

Here's the diagnostic I promised. In the first session I ask for one concrete decision you're responsible for but not allowed to make.

Almost everyone has one. Responsibility arrives with the title. Authority doesn't. If you can't name the gap, you can't close it.

You close it slowly, on purpose. I call it the salami strategy: "you slice a little bit more and more authority over time." You get the slices faster when you show you see the whole business and not just your old lane.

And stop asking upward for sign-off on decisions you were hired to own. My rule is blunt: "to ask for permission is to seek denial."

Two more first-month rules:

• Have a 15 to 20 minute feedback conversation with your new manager early. Ask what keeps them up on a Friday night. That answer tells you what you're really being measured on.
• Act in the first two to four weeks. Planning feels safe, but it's the slowest way to earn credibility. As I put it to clients: "Which is why I spend probably two to four weeks here and I push them to take action in many different ways."

Days 31 to 60: your direct reports test you

Month two is when the inherited team finds out who you are. This is where most new leaders fail quietly.

The failure looks like help. You fill every gap yourself because it's faster. That's the hero trap, and it teaches your team that you'll cover for them. A leader stepping into a bigger role has to let direct reports sink or swim on real assignments.

When someone is below the bar, say it plainly: "The bar is here. You're here. There is a gap. We need to close that gap now. Here is what I need from you: A, B, C."

I expect visible improvement in 30 days. I allow up to 60.

One client, an incoming acting CEO, inherited an underperforming senior hire from the person before her. The near miss wasn't the performance. It was legal exposure if she handled it wrong.

My advice: document first, send the record to whoever made the original hire, and bring in an HR consultant early. And stop rescuing. People will give you grace for mistakes in your first three to six months, as long as you document your decisions.

If you're avoiding a conversation like that right now, you already know how this goes. It gets more expensive every week you wait. "It's pain now or pain in the future. You pick."

Days 61 to 90: the narrative and the board

By month three, a story about you exists. The only question is who wrote it.

"The worst thing you can do is give the narrative of a reset and let someone else cement it for you." If you announce a reset while the person who set the old culture is still in the room, the reset is dead on arrival.

Pick one measure for the next quarter, not five. "Introduce one number, not five. For the next three months I measure you on this one thing." One number gives the board something to track and your team something to hit.

And accept that the calls get closer. C-suite decisions are usually 51-49. You won't get certainty. You'll get a choice, and a deadline.

What nearly always goes wrong in leadership transitions

After enough of these, the pattern is boring. It's rarely strategy. It's usually one of these five:

1. Taking on responsibility without asking for the authority that goes with it.
2. Rescuing weak hires instead of setting the bar.
3. Grinding alone instead of raising a flag early.
4. Opening firm feedback with a long prequel. "Never ever do stuff like that. You're discrediting yourself."
5. Waiting on hiring decisions. "Don't wait, hire, you have roughly 90 days to find out if it's the wrong fit anyway."

My own step-ups, and what they taught me

In 2007 I was three months into my first consulting job in tech. In a client meeting I spoke up, bluntly, and then wrote the product outline. A week later I was asked to become a product manager. That was my first lesson: a promotion rewards what you did, not what you're ready for.

At 31 I went through an intensive leadership programme with a leadership psychologist. The psychologist's read on me: "I think he is a male authority now and does not know how to wield it." The psychologist was right. I had authority. I didn't know how to use it without armour.

In 2017, at 37, I became CEO of a Canon-owned company while holding the CEO, CFO and CTO roles at once. I was one of Canon's youngest CEOs. I call the two years that followed hell: hiring eighty people and flying between Europe, Japan and the US. I went on to scale Arcules, a Canon and Milestone backed AI company, to 150+ people and exited in 2024.

I'd never have sustained that growth without coaches and mentors. What I wanted most, and didn't have enough of, was someone who'd done the job and would get their hands dirty with me. That's the kind of executive transition support I try to give now in my 1:1 advisory work.

How long executive transition coaching takes and what it costs

Change in a leader takes longer than a quarter. My rule of thumb: "Take eight weeks to change the brain... another eight weeks for you to actually see and believe it." That's why my minimum for this work is three to four months.

The structure I use, as published on the CEO coaching page:

• A full-day discovery to start.
• Weekly sessions for the first three months.
• Quarterly deep dives after that.
• Measurable results expected inside 4 to 8 months.

Bigger transitions run longer. My longest engagement ran 12 months, for a company of over 100 employees that needed a C-level rebuild. If you aren't changing seats and want the same weekly format for the role you already hold, the guide to one on one executive coaching covers how that version works.

On cost, the neutral answer: experienced executive coaches charge $500 to $1,500 an hour, and C-suite or CEO specialists $500 to $3,000 and more, usually packaged as a monthly retainer, commonly $3,000 to $10,000 and up, or as a six to twelve month engagement. The full breakdown is on the executive coaching cost page.

How to choose a transition coach, and who shouldn't hire one

Pick someone who has made the jump you're making. A coach who has only coached will ask good things. A coach who has run a company will also tell you which call is 51-49 and which one isn't close. The guide to choosing an executive coach covers the full screen.

Just as important: who this isn't for.

• If you're not ready to change, don't hire a coach. "Sometimes I start working with people and they're not ready for change. I eject people then. If we are a month in and you're not taking action, I will say, maybe we should terminate early."
• If you have no real authority at all, coaching won't fix it. I've refunded a client who was stuck in a political fight with no decision rights. Constrained authority is workable. None isn't.
• If you want the organization fixed in two months while you stay the same, that's a red flag for me, not a goal.

Frequently asked questions about executive transition coaching

Is there such a thing as a transition coach?

Yes. A transition coach is an executive coach who works with a leader during a specific change in role, such as a promotion, an external hire into a senior seat, or a first CEO appointment. The work is time-bound, usually focused on the first 90 days and the following months, and centers on stakeholders, authority, team decisions, and early credibility rather than long-term skill building.

How long does transition coaching take?

Transition coaching engagements commonly run six to twelve months. A typical structure starts with a discovery session, followed by weekly sessions for the first three months and less frequent sessions after that. Shorter engagements of about three months exist, but behavior change in a new role usually needs more time than one quarter to show up in results.

What is the average cost of an executive coach?

According to the market range published on the Leaders ADAPT executive coaching cost page, experienced executive coaches charge $500 to $1,500 an hour, and C-suite or CEO specialists charge $500 to $3,000 and more. Coaching is usually packaged as a monthly retainer, commonly $3,000 to $10,000 and up, or as a six to twelve month engagement. Price depends on the coach's operating experience, session frequency, and the seniority of the role.

How is transition coaching different from onboarding?

Onboarding is run by the organization and teaches a new leader its systems, policies, people, and culture. Transition coaching is run by an independent coach and works on the leader's own decisions: which relationships to build first, where authority is missing, what to change, and what to leave alone. Onboarding usually ends within weeks. Transition coaching typically continues for several months.

When should executive transition coaching start?

Executive transition coaching works best when it starts before or in the first weeks of the new role, while first impressions are still forming. Starting in month four or later is still useful, but by then direct reports, peers, and the board have usually formed a view of the new leader that takes longer to change.

Is transition coaching different for an internal promotion and an external hire?

Yes. An internal promotion often means leading former peers, some of whom wanted the role, and resetting old working relationships. An external hire has to learn the culture and the unwritten rules fast while building credibility from zero. Executive transition support covers both, but the first month's priorities differ: relationships and boundaries for internal moves, context and trust for external ones.

Your first 90 days start before day one

If you've read this far, you probably already have a gap between what you're responsible for and what you're allowed to decide. That's normal. Leaving it unnamed isn't.

Do three things this week. Name the one decision you own but can't make. Pick your one number for the quarter. Book the conversation you've been avoiding.

Day 90 is the deadline the story about you gets written by. Everything above is about writing it yourself.

Get a second set of eyes on your transition

My 1:1 advisory work for new leaders follows the structure above: a full-day discovery, weekly sessions for the first three months, and quarterly deep dives after that. The discovery day is where we find the conversation you've been shying away from, and we script it before week two.

If you're weighing executive transition coaching for your own step up, do one thing first: write down the date your first 90 days end. Then book a discovery call before that date does the deciding for you.
