Ex-Google Employee on Scaling an Organization

"With 70 people the odds that two people are working on the same thing are probably pretty low. With 17,000, it’s almost a 100% that two or three people will be working on the same idea, or at least very similar ideas, at different parts of the organization. I think there is a certain amount of cost to just coordinating that activity. I’ve been really impressed with how Google has been able to scale, but inherently it has to change – just because there’s that coordination cost."
