Everything I can find about pair programming or mob programming is anecdotal. Have there been any statistically significant studies that either confirm or deny the claims that pairing/mobbing increases long term productivity of a team?
Anybody with so little else to do as to conduct that study would almost
certainly close ranks with the non-programming consultants who palmed off pair
programming as "a thing." Anybody who actually programs for a living can see
that the practice is "one guy doing all the work while the other guy slows him
down."
