Matt Cornell suggests a dozen good ways to get an office into productivity by looking at individual’s habits as a group.
Create an information radiator  (e.g., a big wall chart) that shows things like: size of each person’s email or paper backlog, # of days since last emptied inboxes, # of weeks since last weekly review, # of times checking email/day, etc. NB: Must be done positively, and without shame or guilt.
There’s no point relying on every person in an organization to take the initiative, it will probably never happen. However, when you involve everyone in a positive manner, things could get rolling very quickly.
