Mob Programming: When Is 5 Heads Really Better Than 1 (or 2)?

itwbennett writes: Proponents of Mob programming, an offshoot of Pair programming in which the whole team works together on the same computer, say that it increases both quality and productivity, but also acknowledge that the productivity gains might not be readily apparent. "If you measure by features or other classic development productivity metrics, Mobbing looks like it's achieving only 75 to 85 percent of individual or Pair output for, say, a team of six or seven working for a week," says Paul Massey, whose company Bluefruit Software is a heavy user of the Mob approach. So, where does the productivity come from? Matthew Dodkins, a software architect at Bluefruit says the biggest gains are in code merges. "In a day spent using traditional collaboration, you would have to first spend time agreeing on tasks, common goals, deciding who's doing what... and then going away to do that, write code, and come back and merge it, resolve problems," says Dodkins. By bringing everyone into the same room, "we try to merge frequently, and try to do almost continuous integration." Matt Schartman, whose company Appfolio also uses Mobbing and wrote about his experience, gave Mobbing high marks for producing a quality product, but didn't find that it improved productivity in any measurable way.
