Thinking out loud: what a shared puzzle teaches a team

Put a team in front of a puzzle that nobody can solve alone in the time available, and within a minute you can see how that team really works. Who speaks first. Who notices something and keeps it to themselves. What happens when someone gets it wrong.

A break is a good place to see it, because nothing is at stake. And the habits that make the puzzle go well are the same ones that make the work go well.

1. Say what you see

In a shared puzzle, information is spread out: each person is looking at a different corner. The team that does well is the one where people say it out loud, even when it seems obvious. "There is one here for sure." "This side is safe." Most of what a team loses, at a puzzle or at work, is something somebody knew and did not say.

2. Split the ground

Twelve people piling onto the same spot get in each other's way. Thirty seconds spent on "you take the left, I'll take the top" pays for itself straight away. Dividing the work before starting feels slower and is almost always faster.

3. Mark the risks for the others

When you know something is dangerous, leaving a visible mark protects the person who arrives after you. It is a small act, and it is the difference between a group of people working near each other and a team.

4. Treat a mistake as the team's

Somebody will get one wrong. If the reaction is a laugh and "all right, we have two left, let's be careful over there", people keep taking part. If the reaction is a sigh, the next person hesitates, and a team that hesitates is slow.

Trying it in five minutes

MinesBrawl is built around these four habits. Everyone works on the same board at the same time, flags are shared so one person's warning protects everybody, and the team has three lives per board, so a mistake costs something without ending the round. If your team prefers words to numbers, StickBrawl asks for the same kind of cooperation one letter at a time.

• Before starting, agree in one sentence how you will split the board.
• During the round, say out loud what you are sure of.
• Afterwards, take one minute: what did we do well, and what would we do differently?

That last minute is where a break turns into something the team keeps.
