The rumor at Apple was that Steve capped many of the teams in Cupertino. Mac OS X and Marketing Communications being two successful teams that had their headcount capped. During the 2000s, while Apple was gaining traction across the planet, the team responsible for getting the word out, Marketing Communications (“MarCom”), was allegedly capped at 100 heads. The reasoning I heard was that Steve wanted to keep the teams feeling small, but, more importantly, I think he wanted to keep them knowable.
You know, this works for software and hardware too. The less features or parts, the more “knowable” it is to you. It is also a good reason to stick with something (or in the above example, someone) for a long time. Anytime you make a replacement it costs not only time but knowledge. On a team, it means that someone has to get caught up to speed in knowledge and trust has to be re-formed over time. Those same things apply to objects as well.
Think about this the next time you are considering that shiny new to-do manager or “minimalist” text editor over the one that you already have and know really well.
