Over time the teams have gotten smaller, faster, and more informal. In 1960, software development meant a roomful of men with horn-rimmed glasses and narrow black neckties, industriously writing ten lines of code a day on IBM coding forms. In 1980, it was a team of eight to ten people wearing jeans to the office and typing into VT100s. Now it’s a couple of guys sitting in a living room with laptops. (And jeans turn out not to be the last word in informality.)
