Please Do Not Erase

The Ghost Gauge and the Shared Office Whiteboard: A Survey of Residual Notes, Reported as Distributions

A civic-minded brochure from the School of Continuous Improvement presents the Ghost Gauge, a clipboard-and-ruler survey of how long a half-erased note survives on the shared whiteboard of an open-plan office, reports the readings as distributions rather than single figures, and records the University's rule that no whiteboard it owns is wiped until the ghost on it reaches the surveyed median age.
