Smarties hailing from different backgrounds (and/or with different ways of thinking) working together is much more effective than separated, homogenous groups of smarties in almost every way. After all, there are many different kinds of smart and mixing them up results in amazing things. You’ve probably read how small, cross-functional teams are much more effective than your typical silo-ed team approach. I believe that to be true. But there is more to it than that. Cross-function is one part, but it’s also important to create diversity within a particular function. Not all designers are alike, not all engineers think the same way, etc. When you find a group of smart people that share a vision, but offer up different ideas on how to get there, that’s when the magic really happens. I’m calling this “Collaborative Diversity” and I think it’s a great way to work.
