The first hundred days are already booked. A new C-suite seat does not arrive with a blank diary. It arrives with reviews that look like control, courtesy meetings that look like loyalty, and a pack that arrives too late to change. If you do not write the first no before those hours land, the organisation will write your job in the corridor, and you will spend the hundred days proving you are available.
I coach operators who have just taken a finance or chief-operating seat. The brief is usually the inherited calendar and the decision-rights map, not a transformation slide. People will talk about a plan for the first hundred days as if the days were empty. They are not empty. They belong to someone else’s fear. The last occupant left a cadence. The chair left a list of people you should “just see.” The functions left monkeys. Courtesy is how those gifts become the job.
Chief Executives books that as one-to-one work, often as a role transition. It is not an onboarding sprint. It is not outplacement. It is not a search brief. The first no in an incoming seat is often dull: I will not chair that steering group; I will not take home the pack that belongs to someone else; I will not sit in for a quarter. Dull is how a professional seat actually starts.
Open the diary before you open the plan
Michael Watkins’s How Managers Become Leaders is blunt about the shift: the skills that got you the seat are not the job. For an incoming operator, the trap is to take the seat and then do the last job faster — more reviews, more lines, more presence, a hundred-day plan that adds work to a week that already cannot hold the last list. That is how you become the informal controller of everything and the owner of nothing.
The pack will lie in a particular way. It will be complete, late, and written to survive a committee. The diary will tell the truth. William Oncken and Donald Wass, in Management Time: Who’s Got the Monkey?, described how other people’s work climbs onto a manager’s back in the corridor. An incoming C-suite seat is a magnet for monkeys. Every function that was waiting for a grown-up will offer you theirs in week one, dressed as a courtesy read-in.
I ask for three lists in the first fortnight, in the executive’s words.
- Meetings I will attend because the decision is mine.
- Meetings I will stop attending because the decision is not mine.
- Packs I will not take home.
If we cannot write those, we do not have a transition brief. We have a courtesy tour. Name who decides before the organisation names it for you. That is the same muscle as a strategy offsite is not a decision: write the stop, or do not book the days.
A hundred-day plan that cannot kill a meeting is a wish. It will be filed. The week will continue. Presence is the curriculum. Absence can be too, if you choose it early enough that it still looks like design.
Courtesy is how the hundred days get spent
People will invite you to dinners that are lobbies, steering groups that stalled under the last occupant, and “just a quick read-in” that is a dump of unresolved fights. Loyalty is not a reason to keep those hours. Courtesy without a decision right is how you become everyone’s second line.
The first no in a finance or operating seat is often dull. I will not chair the systems steering group. I will not take home the commercial pack that belongs to the commercial lead. I will not be the informal chief executive of a country I do not run. Dull is good. Dramatic nos in month four are usually theatre: you waited until you were resentful, and the cancellation now sounds like a mood.
Sitting chief executives who hired the seat have a quieter version. They ask the incoming operator to “just sit in for a quarter” so the team does not feel abandoned. That quarter is how the job gets written in the corridor — the same judgment as the incoming CFO does not inherit a clean week. If you are the person who hired the seat, your loyalty is the problem. Hand over the recurring decision in writing. Stop attending. The hire cannot look senior while you still occupy the chairs.
Incoming operators after a deal have a stacked version. Two cadences, two guest lists, a town hall already filmed. Integration is a stop list, not a speech. If both inherited hours survive your first hundred days, you did not take a seat. You stacked two diaries and called it a transition — the same failure as integration is a stop list, not a town hall.
Four offers that arrive before week three
“Just chair this while we find someone.” They have already failed to find someone. A clean no: that is not this seat. Here is who it belongs to. If you take it, you have taught the organisation that your hundred days are a parking place.
“The last occupant always did the town hall.” Ritual looking for a new host. A clean no: I will do my own, on my cadence, if the decision is mine. Courtesy is not a reason to inherit someone else’s theatre. A town hall in the first fortnight is often a delay with better lighting.
“Can you take a look at this pack tonight?” A test of availability. A clean no: send it to the owner. I will review on Thursday. If every pack can find your evening, you do not have a hundred days. You have a lobby.
“Just sit in for a quarter.” A monkey in loyal clothing. A clean no: I will attend if the decision is mine. Otherwise I will not. A quarter is long enough for the organisation to learn that the new seat is on probation and the inherited hour is not.
None of these require a character judgment. They require a first no said early enough that it is still a design choice, not a confrontation. If you wait until month three, you will be cancelling a job you already accepted with your attendance.
Time is the constraint the welcome note will not name
Michael Mankins, Karen Brahm and Gregory Caimi wrote Your Scarcest Resource about organisational time: the hours already allocated before the new idea arrives. You are the new idea. The hours are not free. They are twelve operators, a pack, a room, and the hour after the room in which nobody decides because the real conversation happens in the corridor.
A diary full of loyal attendance is a high-status form of motion. The welcome note will praise your listening tour. The organisation will learn that your seat is a corridor. A quiet Tuesday with one killed forum is closer to a professional C-suite than a hundred days in which you were present for everyone.
What I will not do with those days
I will not help you write a hundred-day plan that adds workstreams to a diary that cannot hold a kill. A plan is how courtesy survives a first look. Kill one ritual this month, or do not call it a transition.
I will not facilitate a listening tour so that ending a meeting feels softer. A listening tour is how loyalty re-collects signatures. Take the first no in the ELT, not in a series of private apologies.
I will not treat “just sit in for a quarter” as onboarding. A quarter is a veto you have not declared. If the decision is theirs, your quarter teaches the room that the new seat is a costume.
I will not produce a dashboard for the chair of “how the transition feels.” Process can be shared: dates and scope. Content stays with the executive. Incoming seats attract sponsors. Sponsors attract leaks. Design beats hope.
Write the no before the courtesy lands
Write the sentences before week two, not after the dinners. “This review ends in June because the decision now sits with X.” “I will not attend the country call.” If you cannot write the sentence, you are not ready to cancel.
Say it once, in writing, to the people who actually attend. Then keep it. The first week after a cancellation, someone will book a “quick catch-up” that is the meeting in a smaller room. Decline the catch-up. If the issue is real, it has an owner. If it has no owner, that is the next sentence, not a reason to resurrect the hour.
The clean week will not be given to you. It is made by deletion.
A takeaway you can keep
| Inherited offer | What it is | A first no you can keep |
|---|---|---|
| A hundred-day plan with no kill list | Motion on top of a full diary | “This review ends, or it changes its terms.” |
| “Just sit in for a quarter” | A monkey in loyal clothing | “I will attend if the decision is mine. Otherwise I will not.” |
| A pack on Sunday night | Someone else’s lag | “Tuesday or we do not discuss it.” |
| A courtesy dinner that is a lobby | A second job | “No. Send the issue in writing to the owner.” |
If you can write those nos, enquire. If you cannot, write them before the courtesy tour starts. The first hundred days are already booked. The only question is which of those bookings you will refuse. Fees and fit stay in writing.
