|---|---|---|
Purposedifferent | For technical contradictions or trade-offs, the method looks for solutions that resolve opposing requirements at the same time. It translates limits into an explicit picture of conflict that becomes workable. This produces not just compromises but more elegant principles. | When a group without a fixed agenda needs to get into useful conversations quickly, Lean Coffee structures the start around interests rather than a presentation. The group itself negotiates which topics get time first and which wait. |
