Promiscuous Pairing - What Really Makes Pairing Work
summary
Claim: swapping partners rapidly and rotating expertise produces much higher throughput than traditional pairing. Teams use an egg timer and change retros to separate Discovery (experiment + data) from Improvement (engineer + adopt). Best-performing routine is promiscuous pairing with 90 to 120 minutes swaps, replacing the expert each rotation and often starting stories with the least qualified person; the measured result is roughly a 5x velocity uplift on one team and an additional ~20% drop in defects for the fast‑rotation + avoid‑expert combo, but it requires a fast feedback/improvement process to avoid amplified pain.
