Episode 57 — Operate a Controls Calendar: Scheduling, Evidence, and Sustainable Compliance

This episode teaches how to operate a controls calendar so OT controls are tested, evidenced, and maintained on a predictable rhythm that supports both compliance and reliability without creating last-minute panic. You’ll learn why a calendar is more than dates on a page, because it defines who performs control checks, what evidence is collected, what systems are affected, and how activities align to maintenance windows and safety approvals. We cover practical examples such as periodic access reviews, backup integrity testing, firewall rule reviews, account recertification, patch coordination checks, incident exercise cadence, and monitoring health verification, emphasizing that each activity needs a clear procedure and a repeatable evidence package. The episode also explains how to handle drift, missed cycles, and changing scope, because OT calendars fail when plants add assets faster than governance updates and evidence processes cannot keep up. Troubleshooting considerations include building escalation rules for overdue controls, designing lightweight evidence capture, and using trend reporting to show whether compliance is sustainable or only achieved through heroics.
