The 1-2-4-Silent All is a facilitation technique that focuses on the problem space. It can work with any team size, although 8 to 16 is its sweet spot.
It begins with silent reflection to answer a prompt, then breaks teams into pairs to discuss and pick the best ideas, merges pairs into quads for further refinement and then utilizes silent negotiation to arrive at the most important 2 or 3 problem areas.
