Rooted

Growth That Holds. Build the most profitable tree, then find out what the leaves you promised actually weigh.

A team's Rooted structure part-way through a round: weighted cloth revenue pouches, each hand-marked with a dollar value, hanging from K'NEX rods.

The premise

Three to five teams. Ninety minutes. One instruction: build a structure that can support rapid growth without collapsing under the pressure.

The leaves are your revenue — your clients, projects and sales. The branches are your channels and delivery. The trunk is your systems. The roots are culture and values, and they earn nothing at all.

Leaves are not printed cards. They are weighted cloth pouches, each hand-marked with its value, and a $35,000 promise hangs heavier than a $2,000 one. Profit is revenue minus costs minus penalties, and a structure that cannot hold what you promised will say so in front of the room.

What participants do

Everything is bought, nothing is given

Rods and connectors are ordered from the Bank on a purchase order, priced per bundle — and the sturdiest connectors cost thirty times the cheapest. There are no returns on materials or on leaves, so every purchase is a decision you keep.

The Broken Promise penalty

Requesting a leaf registers it to your team, and from that moment it is a commitment. A leaf you cannot hang legally by the end of the round costs you half its value and earns nothing — so an ambitious order placed early can be the thing that loses you the round.

The market reopens when it said it would not

Round two announces that the market closes for good. Then, late in the round, it opens again. What a team does in that window — and what it does to their half-built structure — is usually the most argued-about moment of the debrief.

The building code is inspected, not trusted

Leaves must hang freely, from rods only, touching neither the ground nor the trunk nor each other. A facilitator inspects every tree before scoring, and a leaf that breaks the code earns zero regardless of what it cost to hang.

Debrief and measurement

Participants around the table during a Rooted session, purchase orders and tracking sheets in front of them.

The debrief runs longer than the game and is where the session earns its place. It opens on the scoreboard and the photographs of any collapsed trees, then moves to the question teams actually want to argue about: what happened inside your team when the Market reopened.

From there it works through organisational balance — the tension between revenue growth and the structure carrying it — and into systems thinking, identifying the reinforcing loops behind both the growth and the collapse. A benchmarking section closes it, calibrating what the team built against what was possible.

Designer’s note

Rooted exists because of one decision: the leaves are weighted.

Every business simulation I have seen represents revenue with a card or a token, which means revenue costs nothing to hold. Here the leaves are cloth pouches, hand-marked, and a thirty-five thousand dollar promise physically weighs more than a two thousand dollar one. Teams chase the big numbers, hang them on a structure built for smaller ones, and watch it sag in front of them.

The roots are the other half. They are culture and values, they cost money, and they earn nothing at all — no revenue, no score, no return anyone can point to. Every team works this out in the first ten minutes and most of them buy the minimum. The structures that hold are not the ones carrying the most leaves.

Ninety minutes is deliberate. The pressure has to be real enough that teams commit before they have finished thinking, because a team that plans carefully builds something sensible and learns very little from it.

Questions

How many participants?

Twelve to twenty-five, working in three to five teams. The scoring depends on teams competing in parallel, so smaller groups lose the comparison the debrief relies on.

How long does it take?

The simulation itself runs ninety minutes: two fifteen-minute build rounds plus briefing, planning and scoring. With the full debrief it is a half-day session.

Is this physical or digital?

Physical. Teams build with K'NEX and the collapse has to be real for the session to work. There is no virtual version.

What do the parts of the tree represent?

Leaves are revenue — clients, projects and sales. Branches are channels and delivery. The trunk is systems. The roots are culture and values. Profit is revenue minus costs minus penalties.

What is the building code?

Leaves must hang freely from rods only, never from connectors, and may not touch the ground, the trunk or another leaf. Any violation earns zero revenue for that leaf.

How much do materials cost?

Prices vary sharply by piece. Rods run from $400 to $2,000 a bundle and connectors from $150 to $6,000, so the strongest joint is also the most expensive one — and teams have to decide what structural quality is worth.

What happens if a tree collapses?

The team loses half the value of the tree. It is the most instructive thing that can happen in the room, and facilitators are trained not to prevent it.

What space does it need?

A main room with a table per team, a central Bank table, and a separate or visually screened area for the Market. Teams should not easily see each other's structures.

Do facilitators need to be certified?

Yes. Setup accuracy and code inspection both matter, and the surprise market window has to be handled precisely, so certification covers the full script.
