The Mac team they were all in one building and they eventually got to one hundred people. Steve had a rule that there could never be more than one hundred people on the Mac team. So if you wanted to add someone you had to take someone out. And the thinking was a typical Steve Jobs observation: “I can’t remember more than a hundred first names so I only want to be around people that I know personally. So if it gets bigger than a hundred people, it will force us to go to a different organization structure where I can’t work that way. The way I like to work is where I touch everything.” Through the whole time I knew him at Apple that’s exactly how he ran his division.
