Three Times Is Enough

A Single-Site Teaching Case of the Ninety-Second Rule

A paper from the School of Continuous Improvement follows one café franchise outlet's badge-clock rule, which automatically enrols staff in a written improvement plan after three lateness flags of ninety seconds or more within a rostered fortnight, with no manager override recorded across eighteen months and the tolerance narrowing four times over that period.
