What to do
- Have participants stand up.
- Have them look around the room and silently select two people. Tell them not to reveal who they have picked!
- Instruct participants that when you say “go” they should try to make an equidistant triangle with those two people and avoid making eye contact. That means they should stand so there is an equal distance between them and each of the two people selected.For example, if I picked these two people (point to the chosen individuals), I would stand somewhere around here (move to an equidistant space between the two people to provide a visual example). If one of the people moves, I also have to move with them to keep the equidistant triangle intact.
- Instruct participants that they are to keep their original two people throughout this activity. They must keep the triangle intact. No talking. No touching! Okay, get into position.
- Once they have had a few minutes to get into place, instruct participants that you are going to touch one of them on the shoulder and move them to a new location.
- Instruct everyone that they must all try to maintain their equidistant triangles as this person is moved.
- Repeat the exercise 2-3 times with each participant maintaining focus on the original two people chosen.
Debrief
(following the activity)
- What did you observe during this activity?
- Did anything surprise you?
- How does this relate to your work?
In his book The Fifth Discipline: The Art & Practice of the Learning Organization, Peter Senge offered this simple, yet profound idea: “Small changes can produce big results – but the areas of highest leverage are often the least obvious.” Here, he refers to what systems thinkers call “leverage points” – well-timed, well-placed actions that can produce significant, lasting improvements/changes. Most people immediately grasp the concept of leverage points, but to spot them in an actual system is often more difficult. This exercise quickly illustrates the concept of leverage points through concrete changes made to the group’s structure when one person is moved.
