1. A method of determining complexity of a collaborative effort comprising: receiving data via a processor, the data comprising identities of social actors or sets of social actors in the collaborative effort, and storing the data in a repository accessible by the processor; defining nodes, via the processor, and associating the nodes with each of the social actors or with each of the sets of social actors in the collaborative effort, the nodes representing each of the social actors or each of the sets of social actors; identifying, via the processor, one or more dimensions for each social actor or for each set of social actors; defining edges between a pair of actors or a pair of a set of social actors, via the processor, and associating the edges with the difference in the values of the dimensions for each social actor or for each set of social actors; defining a coordination complexity (G), via the processor, based on determining, for each dimension, a summation of the respective difference in value associated with the respective edge between every two of the nodes, multiplying the summation by a weight specific for that dimension, and adding each of the multiplied sums for each dimension; and displaying the coordination complexity (G) on a user interface functioning via the processor.
