Dan Levenson presented on improving code review workflows through pair code reviews. Traditional stepwise code reviews can lead to dead time between reviews and large pull requests going unreviewed. Pair code reviews aim to minimize this by having the developer and reviewer schedule a one hour block to conduct the review together through conversation. This allows questions to be asked and issues addressed in real-time rather than through comments. While it can introduce bias, pair reviews have led to less dead time between reviews and a more collaborative culture at Healthify.us where Dan is CTO.
