Is information not flowing as well as it needs to? Do you suspect bottlenecks? Visualize the ways information flows to find starting points for improvements. If you want to look at one specific flow (e.g. product requirements, impediments, ...) check out Value Stream Mapping (#79). For messier situations try something akin to Cause-Effect-Diagrams (#25). Look at the finished drawing. Where are delays or dead ends?

Now collect every group's two action items and have a vote on the final two.
