Episode 38 — Define OT SLAs: Internal Versus External Expectations That Protect Uptime
This episode teaches how to define Service Level Agreements that reflect OT priorities, because uptime protection depends on clear expectations about response, restoration, and communication when systems fail. You’ll learn the difference between internal SLAs, which align teams across engineering, operations, IT, and security, and external SLAs, which bind vendors and service providers to measurable commitments. We explain key SLA elements in OT terms, including availability targets, response time, time to restore, maintenance window coordination, escalation chains, and what constitutes an “incident” versus routine troubleshooting. The episode emphasizes that SLAs must be realistic for OT constraints, such as limited patch windows, vendor-only change authority, and the need to validate process state before interventions, otherwise the SLA becomes a source of conflict during outages. You’ll also learn how to connect SLAs to security outcomes, such as requiring timely credential revocation, rapid containment support, and evidence delivery after events, so uptime and security reinforce each other rather than compete.
