Triangles

Choose this exercise

Purpose: Demonstrate physically how a change made by one person directly affects everyone else in an interconnected group.

Use it when: Use before discussions on complex systems, team interdependence, or organizational change to give a shared physical reference point.

Skip it when: Skip if the room lacks open floor space or if multiple participants cannot navigate moving crowds comfortably.

Group arrangement: Whole group moving together in an open room

Timing: Relationship Makers Handbook suggests under 5 minutes; UWT suggests 10 minutes to allow setup, two short rounds, and structured debrief.

Materials and tools

• No special materials.

Before participants arrive

1. Clear a central floor area large enough for all participants to walk without bumping into furniture or walls.

Say this to open

Without speaking, look around the room and silently choose two other people. Keep your choices completely secret. Do not stare or point. Your job once we start is to walk so you stay equal distance from both people, forming an equilateral triangle where you are one corner and they are the other two. As they move, you will need to adjust.

How to run it

1. Set ground rules and choose targets 2 minutes

   Explain safety rules: walking speed only, no physical contact, keep eyes up, and no verbal communication. Have everyone silently select Person A and Person B without revealing their choices. Example: If you choose Sarah and David, you must position yourself so the distance between you and Sarah equals the distance between you and David, and the distance between Sarah and David.

2. Run round one 3 minutes

   Tell the group to begin moving. Everyone adjusts their position to maintain their triangle. Let the room move until the system settles into a stable pattern or until two minutes elapse. Ask everyone to freeze in place.

3. Run round two with a disturbance 2 minutes

   Ask everyone to remain frozen. Gently ask one volunteer to take five large steps in any direction and freeze. Tell everyone else to adjust to re-establish their equilateral triangles without talking. Observe the ripple effect until the room settles again.

4. Debrief system dynamics 3 minutes

   Gather the group into a circle or seats. Ask two selected debrief questions to connect the physical movement to team dynamics. Take two or three brief comments per question.

Debrief questions

• What happened across the entire room when just one person moved?
• How did it feel trying to balance your position while your reference points were also moving?
• Where do we see this kind of ripple effect in our daily work or team projects?

Finished output: A shared group experience illustrating systemic interdependence, concluded when the room reaches physical equilibrium twice.

Remote

This physical exercise cannot run online without changing into a completely different digital board simulation. For a remote team, use a digital whiteboard mapping exercise where participants draw arrows connecting three team roles and discuss real work dependencies instead.

Hybrid

Hybrid delivery is not recommended. Remote participants cannot share the physical space needed for the mechanic. If running with a mixed group, assign remote members the role of system observers who track motion waves via webcam and share their observations during debrief.

Access and participation choices

• Participants with limited mobility can move at their own pace or serve as stationary anchor points while others adjust around them.
• Anyone may choose to observe the systemic motion from the perimeter without needing to disclose a reason.

If the session gets stuck

Participants walk too fast or bump into each other.

Call freeze immediately. Remind the room that only slow walking is permitted and open floor awareness is required.

The group never settles and keeps circling endlessly.

Call freeze after 90 seconds. Explain that closed circular dependency loops sometimes prevent total rest, which is itself a valid system lesson.
