|---|---|---|---|---|
Purposedifferent | 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. | When features need to be distinguished by their effect on satisfaction, it makes expectations and surprises comparable. It separates basic needs, performance contribution, and delight. | When loud voices could dominate a round, Nominal Group Technique protects individual thinking time from group effects. It collects ideas separately first and only then enables shared weighting. | When a complex topic does not yet have a fitting agenda, Open Space Technology hands topic ownership back to the participants. The format suits questions that only move forward when real interest determines the order. |
