A
Let the most eager offices begin first and compare them with reluctant offices.
B
Start all offices at once and compare productivity only before and after launch.
C
Give early offices extra implementation staff not available later.
D
Choose start dates according to each office's recent productivity decline.
E
Randomly assign offices to different start dates, collect outcomes in every office during every period, and compare early versus not-yet-treated offices while accounting for calendar period.
