Or a large, international organization with employees and clients all around the world, each of whom believe that their problem is the most important thing in the world.
I've worked for some of the largest corporations in the world, 3 of them in the fortune 100 one of which is a fortune 20 company.
I've seen it done well and done poorly at that scale. What the person I replied to was describing is a dysfunctional organization, not a functional large organization. Creating a large functional organization is just like creating good abstractions in software. You have to figure out how to structure things so that teams/business units can work together with minimal communication across teams.
