| Criterion |  Innovation Double Diamond |  Facilitation 1-2-4-All |
|---|---|---|
Purposedifferent | For complex problems with a fuzzy situation, the method cleanly separates search space and decision. It first creates breadth in understanding and then focus in elaboration. This brings open questions, problem definition, and solution path into a traceable movement. | 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. |
