Gigamaps are about other things than mapping out facts, entities and relations. They are also about sharing a sense of the complexity at hand. If members in a team have a diverging sense of the complexity of the task at hand we got a problem. The person who thinks it is a simple task will allocate far less resources to the project than the person who thinks it is very complex.There are other types of sense sharing, the sense of needed effort, resistance to the project, time needed etc.
Read more about Gigamapping as sense sharing in the working paper from RSD4 2015 below.
A full version of this paper, where the arguments are substantially developed will be published in a Springer Book on Systemic Design soon (Editor Peter Jones)
