So it's "microservices" now? Mongols figured out around year 1200 that in a proper military organization, you have one boss and maximum of about 10 subordinates and 10 peers. Though it was already written about by Sun Tzu way earlier. Chain of command ought to be clear from private to general. Romans had earlier found out that a group of about 100 men is good department size for day to day operations. (Roughly the Dunbar number of the least capable members of the group.) Then commercial companies noticed that they don't have to abide to military hierarchy. But they didn't notice the underlying biological tendencies. As a result every second industry fad is reinventing the same social structure over and over again. Factory with departments -> open plan office -> teams -> matrix organization -> sprints -> (I lost track here) -> microservice? Every company has problems. If the biggest problem is poor flow of information between departments/teams, then that company has competitive advantage to the guys who have some serious issues.
