Maximizing Outcome: Approaching Product Development with Both Shift-Left and Shift-Right Practices
summary
The talk describes applying both shift-left and shift-right testing to a retail picking workflow: using Three Amigos to add refinement-level acceptance criteria, and using planned logging, feature flags, and staged rollouts for production validation. They instrumented logs to measure screen-open frequency, ran field research watching pick/pack operations, and released changes in three waves (internal trial, staff training, full launch), resulting in no production incidents and only a few support tickets over months.
