People who professionally influence companies, i.e. those whose job it is to understand corporate decision-making, focus almost exclusively on the dynamics of personal relationships. Salesmen, B2B marketers and even activists all use human behavior as the foundation of their techniques. This thing about corporations being monolithic being-like entities is a "theory without a practice;" we can look to the people who empirically deal with corporations to see that they do not find it useful to think that way.
