The benefits of pair programming are well-known but enabling it is hard. It is clear that incorporating it into the workplace sustainably requires a fundamental shift in culture. After working at 2 startups who implemented different versions of pair programming, I came to Pivotal Labs with my own stories and preconceived notions. Pivotal Lab's engineers (and sometimes designers and product managers) pair program 8hours/day every workday and help enable other companies to practice it with us. It seems impossible but after spending a year fully immersed, the trends in having a sustainable pair programming culture have started to surface. Hear from someone who is a newfound believer in pair programming on the structure Pivotal Labs has put in place to enable it, war stories, and lessons learned.
