A Brainstorm list of ideas generated at a meeting is a classic Harvest piece. The ideas from that list are sent forward into the next stage of the process, eventually resulting in a more significant Harvest.
Harvesting may be part of Divergence, as in the example of a Brainstorm list above, or part of Convergence, as when the a set of visuals is presented to an organization as a unified representation of what took place at a session.
