|---|---|---|---|---|
Purposedifferent | With only a few minutes available and a still-fuzzy solution search, the method forces a wide range of variants. It produces fast sketches before the first idea can settle in, making different directions directly comparable and open to further development. | When many people in a group too rarely get to speak, 1-2-4-All distributes thinking time more fairly. The format builds participation step by step and makes quiet or still-unformed thoughts usable faster. | When loud voices or hierarchy distort the idea search, the method creates a quiet entry into joint development. It gives everyone thinking space and gathers contributions without social brakes, making diversity more visible and easier to build on. | With unevenly distributed speaking time, the method brings every person into the contribution one after another. It prevents early voices from setting the direction while still producing a shared idea space. This makes participation plannable and the team's diversity visible. |
