What Does This Make Possible?
In 1-2-4-All, participants first work alone, second in pairs, then in small groups, to generate solutions to a specific challenge. It engages every voice regardless of group size, generating a kaleidoscopic view of perspectives, and expresses ideas people would otherwise keep to themselves. It sets an active tone for a group and diminishes power differentials. It taps into the group's collective knowledge, leading to better ideas and shared ownership, which simplifies implementation. This structure reinforces LS Principle #1, Include and Unleash Everyone.
Structural Elements — Min Specs
-
Structuring Invitation
"Let's think about our shared challenge and generate ideas to address it. What opportunities do you see for making progress on this challenge?"
-
Space and Materials
Space for participants to work in pairs and quartets [breakouts]. Chairs, tables, and paper are optional.
-
Participation Distribution
Roles include host [tech host] and participants. Minimum group size is four. Everyone has an equal opportunity to contribute.
-
Group Configuration
Alone, pairs, quartets, whole group
-
Steps and Time Allocation
- Intro: Share the structuring invitation and identify the shared challenge. (1 min.)
- Individual Reflection: Individuals silently reflect and write down ideas. (1 min.)
- Pair Up: Participants form pairs to share and build on ideas, trying to defer judgment and keep each idea distinct [breakouts of two or three]. (2 min.)
- Form Quartet: Pairs join to form quartets to refine and differentiate ideas. [Manually merge pairs into quartets.] (5 min.)
- All-Together: Everyone returns to plenary. A few people share something everyone should hear. [Alternatively, use Chatterfall—Each participant types one idea in chat and doesn't hit Enter until prompted. Then everyone scrolls up to see what others wrote.] (7 min.)
Tips & Pitfalls
- Stick to precise timing and facilitate quiet reflection.
- As host, don't over-help or overcontrol the group's conversations.
Riffs & Variations
- Try reversing the order or doing another round to dig deeper.
Practical Applications
- The structure 1-2-4-All can be used to help teams prioritize tasks, get rich feedback after a presentation, unlock a discussion that has become dysfunctional or stuck, or include more voices in a challenging transition.
Online & Hybrid Facilitation
When technology or a large group make it difficult to manually transition from pairs to quartets, try 1-3-All. Skip pairs and go straight from individual reflection (1) to trios (3) before bringing the full group together (All). Keep in mind that with trios, it can be easier for one person to dominate the conversation, so make sure you build in time for everyone to share.
