Systems integrate on schedule after a deal. People don't. Shelley D. Smith on the second calendar employees keep, and how to baseline culture before close.
The deal closes on a Friday, and by Tuesday there's a new logo in everybody's email signature and the dashboard is green.
Payroll moved over, the phones got forwarded, and somebody gave up a long weekend to convert the systems.
The integration team sends a thank-you note and goes back to their day jobs.
Meanwhile, the people who'll decide whether this deal actually works haven't made up their minds yet.
They're keeping a second calendar, and nobody else is watching it.
Here's the short version: in a post-merger integration, the systems have a before and an after. The people usually don't. That's why most companies can prove the conversion worked and can't prove the integration did.
That's the part I promised you last week: what happens after a deal closes, when the systems integrate right on schedule and the people don't.
If you're in the middle of one right now, reading this between two meetings, stay with me.
Because by the end, I'll give you one question that tells you which calendar your company is actually watching.
The first calendar belongs to the deal: sign, close, day one, the first hundred days, the conversion.
It has owners, dates and a weekly status report, and it's the only one that ever makes it onto the plan.
The second calendar belongs to the people.
It's the private one every employee starts keeping the day the announcement goes out, and it runs on questions like these:
Is my job safe?
Does my boss still have any say?
Am I still seen, valued and heard here?
Most people don't leave because of the new logo. They leave because the answer to that third question quietly turned into no.
Nobody posts that calendar anywhere.
People work through it quietly, one small conclusion at a time, and most of them reach their answer long after the integration team has gone home.
Everybody celebrated the first finish line on the conversion weekend.
The second one is the day people decide whether they're staying, and usually nobody is there to see it.
Most of you reading this aren't in private equity, but it's where people get measured hardest, so it's a useful mirror.
AlixPartners surveyed 427 private equity leaders and portfolio company executives at the end of 2025 and found that CEO turnover in those companies spikes around year two, long after the systems went green.
The people underneath feel it, too: 44% of portfolio company leaders said they face a higher risk of losing their top performers.
Same honesty note as the last two weeks.
AlixPartners advises companies through exactly these leadership changes, so findings like these are comfortable ones for them to publish, and I hold that part loosely.
The 44% is the one I'd pay attention to, because it isn't about the CEO at all.
It's about the people who are on the ground doing the work.
This isn't only a private equity story, either.
When Bain surveyed people who do mergers for a living for its 2023 M&A report, culture was an early focus in 80% of integrations, and 75% of acquirers still struggled with cultural issues that required serious interventions.
So almost everybody planned for it, and most of them ended up fixing it anyway.
Paying attention was never the problem.
None of this is the integration team's fault. They did exactly what they were asked to do, and they did it well.
The second calendar was just never theirs to keep.
The plan measures what the plan can see: systems converted, accounts mapped, retention agreements signed.
Every one of those can be green while the thing that matters most quietly goes the other way.
If you read the first piece in this series, you'll remember the hotel where every number was green and you could still feel something was off in the lobby.
That wasn't the only one.
Back when I was running hotels for Marriott and later on the franchise side, I walked into more than one property like that, where the scorecard said one thing and the break room said another.
None of that was on the scorecard.
An integration dashboard has the same blind spot. It only sees what somebody checks, and culture is what people do when nobody's checking.
On the acquired side, the real conversation moves to the meeting after the meeting.
The best people don't complain. They just start taking the recruiter's call.
By the time any of it shows up in a number, the decision was often made months ago.
If this sounds familiar, it should.
Last week was about a new leader who walks in with no record of what the organization looked like the day before, and a deal is that same problem for an entire company at once.
Diligence looks hard at the books, the contracts, the customers and usually the leadership team.
In my experience, though, it's rare that anybody writes down how the place actually worked:
How decisions got made when the owner wasn't in the room.
Who people went to when the process didn't work.
What people said "we" about.
So six months after close, when somebody asks whether the integration worked, there's nothing to compare it to.
The systems have a before and an after. The people don't.
Nobody closes a deal without advisors. There are lawyers and accountants, and people checking the revenue and every contract.
Brad Burke, who advises private equity firms for Insperity, put it plainly on the Association for Corporate Growth's Middle Market Growth podcast this summer.
These firms, he said, "will hire other advisory groups as a regular, traditional part of the process, but oftentimes the human capital aspect is overlooked."
He said smaller firms often skip it entirely, either because the team is stretched or because of what it costs to bring those advisors in before the close.
His answer was that the advisory bench needs someone for this, "whether it's a fractional CHRO or another type of consultant."
Insperity sells HR services to these companies, so of course they'd say that.
But he's describing something most deals have in common.
The first calendar gets a whole bench of advisors, because everything on it fits in a data room.
The second calendar doesn't, so it usually doesn't get anyone.
A deal is one event seen from several chairs. The problem looks the same from every one of them, but where you start depends on which chair is yours.
If you're the buyer: before you close, write down how the company you're buying actually works, not just what it earns.
Then put the people on the hundred-day plan with a measure that isn't a signed retention agreement.
And if this is your second or third acquisition, the people from the last one are watching how you treat this one. That's on the second calendar too.
If you were acquired and you're the one holding it together: you're keeping your own second calendar while you manage everyone else's, and that deserves to be said out loud.
Write down how your side actually works while you still remember it, because the conversion will change it.
Two weeks ago I shared the research on what it costs when the acquired company's internal leaders walk out the door.
Right now, you are the best record of what that company was.
If you own a company and a sale is somewhere in your future: you'll be asked for three years of financials, and almost nobody will ask how your people work.
Write that down anyway. It's one of the few things that still protects what you built after you hand over the keys.
If you're in HR inside any of this: your name is on the payroll conversion, and probably the benefits mapping too. Ask who owns the rest.
Not the announcements, not the town halls, but the answer to whether people actually work differently a year from now.
If nobody's name is on that, you've just found the case for putting one there.
Whichever chair you're in, the first move is the same.
Write down what's true now, while it's still true, so somebody can tell later whether it changed.
Fractional culture and organizational development is the people side of this: culture, values, training and development, succession.
In a transaction, I start the same way I start everything else.
Before anything gets designed, the organization gets heard. Ideally that happens in the quiet window before the close, and if not, as early after it as possible.
What comes out of that is a baseline of how the place actually works, and the means to run it again when the hundred-day plan runs out and again in year two.
That way somebody is finally keeping the second calendar, and when anyone asks whether the integration held, you can show them instead of guessing.
The work happens in four moments, from the quiet window before close through year two.
The first conversation costs nothing. Start one here.
Here's the question I promised you.
Ask your integration team how the people are doing.
If the answer is mostly about help desk tickets, your company is watching the first calendar.
Nobody's keeping the second one, and that's the one where people decide whether to stay.
This is the fourth piece in The Second Finish Line, a series on the gap between the day we declare a change finished and the day it actually is. Next week: a Saturday morning at a flea market in southern Indiana, before I was even a teenager, and the small thing my parents did that turned out to be the whole idea behind the first drop.

Why do employees leave after a merger or acquisition?
Most people don't leave because of the new logo. They leave because the answer to a private question, whether they are still seen, valued and heard, quietly turns into no. That decision usually lands months after the systems integration is finished, which is why it rarely shows up on an integration dashboard in time. AlixPartners' 2026 survey found 44% of portfolio company leaders report a higher risk of losing top performers.
Why do so many M&A integrations struggle with culture even when it's planned for?
Planning for culture and measuring it are different things. Bain's 2023 M&A practitioners' survey found culture was an early focus in 80% of integrations, yet 75% of acquirers still hit cultural issues requiring serious intervention. Integration plans track what they can see, like systems converted, accounts mapped and retention agreements signed. How people actually work usually isn't on the plan.
How do you measure culture during a post-merger integration?
Start with a baseline recorded before the conversion changes things: how decisions got made when the owner wasn't in the room, who people went to when the process didn't work, and what people said "we" about. Then run the same read when the hundred-day plan ends and again in year two. Without a before, there is nothing to compare the after against.
When should culture work start in an acquisition?
Ideally in the quiet window before close, alongside legal and financial diligence. If that window has passed, as early after close as possible. AlixPartners found CEO turnover in private-equity-backed companies spikes around year two, long after the systems go green, so the work has to continue well past the hundred-day plan.
What does a fractional culture leader do during a merger or acquisition?
A fractional culture leader owns the people side the integration plan doesn't: culture, values, training and development, and succession. The work starts by hearing the organization before designing anything, produces a baseline of how the place actually works, and reruns that read at set points so leaders can show whether the integration held instead of guessing.
