The first 100 days as a new CEO
There is no settling-in period. The clock starts on day one and results are expected. Here is what the hundred days should actually contain.

The short answer: spend the first two weeks getting numbers you own, the next four finding where value is trapped, and the rest making a small number of changes that are visible and irreversible. Do not spend ninety days listening. Do not restructure. Do not launch a programme.
And understand the position you are in: your failure and exit have already been modelled by the chairman and the CFO. That is not cynicism, it is planning. Behave accordingly.
The listening tour is a trap
You will be advised to spend your first ninety days listening. Listening is necessary. Ninety days of it is a way of postponing the moment you have to say something difficult.
There is a deeper problem with it. Conversations tell you how people want the business to be understood, not how it works. Everyone you meet in those first weeks has spent a fortnight preparing what they will say to you. That preparation is itself informative — but it is not evidence.
So listen, extensively, but pair every conversation with something you verified independently. The gap between what you were told and what the data shows is the most valuable thing you will learn in your first quarter.
You already know most of what you'll find
The received wisdom says you cannot assess a business until you land. I disagree, and after forty years I can tell you what you are almost certainly inheriting.
- A set of numbers that are not yours, that look backwards, and that have already been shaped to tell a story.
- A business model that was never designed. It emerged, with bolted-on systems and processes, and it has already slowed.
- No reliable view of the true health of the business today.
- A culture set by your predecessor, along with their politics — and it is not yours.
- A board that is not on your side, because they are protecting their own positions.
None of this requires you to be in the building. Public data, the product itself, a conversation with a customer, and the CVs of the board will confirm most of it before you start. Do that work in the gap between accepting and starting. It is the only time you will ever have with the mandate and without the diary.
Weeks 1–2: numbers you own
The single highest-value thing you can do in a hundred days is stop depending on inherited reporting.
Pick a small set of measures that describe the actual flow of the business rather than its accounting output — starting with how long it takes to turn a customer's decision into cleared cash.
Then trace each one to source yourself, once. Not to be difficult — to know. You will find at least one critical number that is compiled by hand, by one person, in a spreadsheet nobody else has seen. That discovery is worth more than the number.
By the end of week two you should be able to say, in a board meeting, exactly where a figure came from and who touched it. Almost nobody in the room will be able to do the same.
Weeks 3–6: find where value is trapped
Around 90% of blocked value sits in the order-to-cash cycle. That is where the money already earned is stuck, and where the machine has slowed.
Time a real order end to end from source dates, then a difficult one. You are looking for the gaps nobody can explain — the eleven days a contract sat with legal, the invoice that could not be raised because a delivery note was never signed.
This produces something no consultant's report will: a specific, dated, undeniable example of the business failing to convert. Bring one to a leadership meeting. It changes the conversation permanently, because it cannot be argued with in the abstract.
The framework is Cash Conversion Velocity, set out in full in The Slow Bleed. Its value is that it belongs to no function and therefore cannot be defended by one.
What to refuse in your first hundred days. A restructure. A new system. A cost reduction programme. A transformation initiative. Every one of these will be proposed to you, usually by someone who proposed it to your predecessor. All four are ways of looking decisive before you know where the constraint is.
Reading the team
You cannot assess a leadership team through interviews. You assess them through decisions.
Give each of them something real to decide within the first month — genuinely delegated, with a deadline. Then watch three things: how they frame the problem, what information they seek, and whether they come back before the deadline when it goes wrong.
Pay attention to how each of them is wired. Some see problems as structural, some as people, some as commercial. That wiring determines the solution they will instinctively reach for, and it will not change. Your job is to know it, not to fix it.
And know your own. Compare your instinctive framing against theirs honestly. A leadership team that shares one wiring has one blind spot, held collectively and invisibly.
Weeks 7–12: one visible change
Somewhere in the second half of the hundred days, do something small, concrete and irreversible that demonstrates the new standard.
Delete an approval step. Kill a report nobody reads. Change one metric that everybody is managed against. Fix the one thing that every single person mentioned in your first month and nobody had authority to solve.
The point is not the change itself. It is that the organisation learns you will actually do things. That is worth more than a strategy document, and it costs nothing.
There is no settling-in period. The clock starts on day one.
The people decision
You will know within six weeks who is not going to work out. You will keep them for six months because you want to be fair, because you are new, and because removing someone early looks impulsive.
Every CEO I have ever spoken to says the same thing afterwards: they moved too slowly. The cost of keeping the wrong person is not their performance — it is what everyone else concludes about your standards while you deliberate.
Be fair, be quick, and be clear about why. Those three are compatible.
Do not walk in unarmed
Would you walk into a bar full of gunslingers with no gun and no vest? Of course not. Yet most CEOs walk into the role undefended — dependent on other people's numbers, inside a model nobody designed, in a room where nobody is on their side.
You can predict nearly all of it before you arrive. The hundred days are not for discovery. They are for confirming what you already suspected, fast enough to still have the mandate to act on it.
The full method is in The Slow Bleed. If you want it applied to a specific business in the weeks before or after you start, that is the CCV Diagnostic.
