The sports programme to build in the first 90 days after a merger, rapid growth or a restructure: what to do week by week, and what to avoid.
The first three months after a merger, acquisition, rapid growth or restructure are decisive. In this period two groups can be physically in the same office yet socially separate: two different companies who sit together, go to lunch together and talk among themselves.
That separation does not close by itself — it has to be broken deliberately. Below is a 90-day programme laid out week by week.
Why sport works
Sports-based formats have a clear advantage in post-merger integration: they rebuild role allocation around the task.
In a meeting, hierarchy decides who speaks. On a sailing boat or a five-a-side pitch, the task decides the role — whoever can do something does it. This lets the two groups get to know each other through capability rather than job title, and that is exactly what is needed most after a merger.
The unbreakable rule: mixed teams
The one critical rule of the whole programme: no team consists of a single legacy company, a single department or a single location.
When you leave team selection to participants, people team up with those they know and the event reinforces the existing split. Team lists must be prepared in advance by HR, deliberately mixed. If this rule is broken, most of the rest of the programme is wasted.
Weeks 1–2: Observation and low-barrier first contact
What to do: A short, non-compulsory in-office format. A stretching workshop or a chair massage day fits.
Why: The first two weeks are when people are most on edge. Anything demanding high participation, physical contact or competition arrives too early at this stage. The goal is not bonding but the signal that "the company is investing in this".
In the same period: Run a short survey to understand the fitness profile, age distribution and interests of both groups. A five-question, two-minute survey shapes the format of the next 80 days.
Weeks 3–6: The first shared event
What to do: A half-day rotating format with a low learning barrier. The three best fits:
- A padel or pickleball day: With rotating mini matches, a participant pairs with 8–10 different people in a day. The most effective introduction mechanism after a merger.
- A sports festival with stations: 6–8 stations, mixed teams, a central scoreboard. Makes room for every kind of ability profile.
- An escape room tournament: No physical participation required; the safest choice for groups with wide fitness differences.
What not to do: Do not choose a ski trip, an overnight retreat or any high-physical-load format at this stage. The participation barrier is high, part of the team will not come, and the split is reinforced.
Weeks 7–10: Building continuity
What to do: Start a weekly recurring programme. A single event produces a memory; a routine produces a habit — and the second is what is needed after a merger.
Options:
- Weekly five-a-side or volleyball: Mixed teams, on a fixed day and time
- An office championship (table tennis, darts): At lunchtimes with a board updated publicly; produces a topic that lasts for weeks
- Weekly yoga, pilates or stretching: For the group with a low physical participation threshold
- A step challenge: Four weeks with mixed teams; includes employees at other locations
The most important detail at this stage is that team composition stays fixed. The same mixed team playing together for weeks produces a familiarity a one-off event cannot.
Weeks 11–13: Shared achievement and closing
What to do: A concrete shared achievement at the end of the 90 days. Two options:
- A tournament final: Finals day of the league or championship that started in weeks 7–10, with an award ceremony
- One large event: A corporate sailing regatta, an obstacle race or a full-day sports festival
A higher-barrier format can now be chosen, because the first ten weeks have built an attendance habit and familiarity across the groups. The sailing event that would not have worked in week 3 works in week 12.
The 90-day programme at a glance
| Period | Format | Purpose |
|---|---|---|
| Weeks 1–2 | Stretching / chair massage plus a short survey | Signal intent, learn the profile |
| Weeks 3–6 | Half-day rotating event (mixed teams) | The first real introduction |
| Weeks 7–10 | Weekly recurring programme or league | Continuity and habit |
| Weeks 11–13 | Final tournament or large event | Shared achievement and closing |
Five mistakes to avoid
- Letting participants pick their own teams. Everyone teams up with people they know and the event reinforces the split. Mixed team lists must be prepared in advance.
- Choosing a high-barrier first event. An overnight retreat or a ski trip belongs at the end of the 90 days, not the start.
- Settling for a single large event. One day is not enough to resolve a split; a programme with continuity is needed.
- Covering only head office. If teams at other locations are left out, the "us and them" perception deepens after a merger. Step challenges and online formats are critical for those groups.
- Presenting the event as the fix for the merger's problems. Events do not resolve unclear roles, job security worries or cultural differences. They produce familiarity; the rest is the job of management communication.
Measure at the end of 90 days
Look at three simple indicators: attendance rate (broken down by group — if one group systematically stays away, find out why), retention in the ongoing programme (how many people still attend in week 13) and the mixed-lunch observation (are canteen tables still divided along legacy company lines).
The third is the hardest to measure and the most meaningful.
