The First 90 Days Decide the Hire

The offer was accepted, you shook hands, and for about three weeks everything looked fine. Then it got quiet. By month four you were quietly asking whether you had picked the wrong person.

Most owners I work with blame the hire at that point. I look at day one instead.

The offer letter is where owners stop paying attention

You spent weeks on sourcing and interviews. Then the person arrives, you hand over a laptop and a login, and you say something like "get to know the team and we'll talk next week." You are busy, because you were busy enough to need the hire in the first place.

A new person in an unclear seat fills the vacuum with guesses. They guess what you care about, who decides what, and which of your habits are rules. Most guess wrong at least once, and you find out a month later when something lands badly. By then both of you have stacked up assumptions that are hard to unwind.

In the Navy, nobody took over a watch without a turnover: what the situation was, what had changed, what to keep an eye on, who to call. It was written down because memory under pressure fails. A new seat deserves the same treatment.

Put four things in writing before day one

One page is enough. If you wrote the seat down before you hired (and if you didn't, the baseline assessment is a fast way to see where your structure is thin), most of this already exists.

• What winning looks like at the end of each month. Make it observable. "Has run the weekly pipeline review twice without me in the room" beats "gets up to speed."
• The one or two numbers the seat is judged on, and where those numbers live.
• Decision boundaries. What they decide alone, what they decide and then tell you, and what they bring to you first.
• One person besides you who can answer how things really work around here.

That last one gets skipped, and it matters. Every company has an unwritten layer: which customer gets a call back in an hour, which vendor is touchy, which report nobody reads. If you are the only source for it, the new hire has to interrupt you to learn it, and most people would rather guess than interrupt the boss.

Schedule the conversations before the work

Put a weekly thirty minutes on the calendar on day one, same day and time, for the full ninety days. Keep the agenda to two questions: what is unclear, and what did you decide this week? The second question shows you how they use the boundaries you set.

Then mark day forty-five. Sit down and say what you see and ask what they see. A gap you find at day forty-five costs you one uncomfortable conversation. The same gap found at day one hundred twenty costs you a search, a severance, and another six months.

Do it Monday

If someone started in the last six months, take an hour on Monday and write the four things. Hand them over even though they are late. Say plainly, "I should have given you this on your first day." In my experience people respond to that with relief, because they have been working without a map and knew it.

If you have a hire coming, write the page before the offer goes out. The hire is yours to get right, and so is the first ninety days.

If the page is hard to write, the seat is not defined yet, and that is worth knowing before anyone sits in it.
