The document discusses how to hold effective meetings for groups tackling "wicked problems", which are complex issues with incomplete information and contradictory requirements. It explains that these meetings require building shared understanding and commitment among diverse stakeholders. The key is using visual tools like shared displays, sticky notes, and graphic recording to facilitate dialogue, develop a common language, and create shared ownership of the problem and potential solutions. When groups establish shared understanding and commitment in this way, it can lead to breakthrough results in addressing even the most challenging problems.
