Each Level of Toilet-Key Custody Maturity Adds Forty-One Seconds to the Wait and Saves No Keys

A paper from the School of Continuous Improvement scores 63 roadside service stations against the five-level Toilet-Key Custody Maturity Model, from Loose to Reconciled, and sets each station's level against the wait for the customer toilet key, the keys lost per year and the share of toilet-bound entrants who asked for it. The median wait rises about 41 seconds per level while keys lost do not differ by level, and the University now issues every key it holds, of whatever lock, on a Level 3 fob of not less than 180 mm.
