Giant whiteboard or butcher paper crowdsourced diagram/s

What do people think of having a large whiteboard or piece of butcher paper where we can diagram the network of goals, people, groups, processes, tools involved with this great project we are involved in? Has anyone out there ever done something like this and know the best way to structure it? I am imagining starting with the land, growers, and people that eat food and mapping how we think our tools and projects should be part of that continuum. Would something like that be useful for others?
