It is a scaling problem, and scaling problems in teams are limited by communications costs. Adding more edges, where artists can talk to programmers more directly and meaningfully without it happening through a mediated hierarchy, improve throughput. Of course, having the ability for subteams to work together more effectively doesn't mean you should always use it or abandon trying to manage the project through normal means.
