This week a conversation from almost a decade ago popped into my mind. In it I was speaking with a brainy friend of mine who was a coder at Microsoft. He and I were talking about how small teams of coders were independent but highly linked. For example, one team might be given the challenge to build the “slide show” function for Powerpoint; another might be given the “inserting pictures” function. Each group would work on their own piece. Every night they would run a routine to integrate all of the code written that day by the various teams. Sound groundbreaking?
