Many buildings have backup plans on paper that fail under real stress. In this episode Alex Morgan interviews Michael Harrington to walk listeners through pragmatic, low-disruption tests that prove generators, UPS, carrier failover, and operational tech actually work together. We cover how to define simple acceptance criteria, schedule tests to minimize tenant impact, capture evidence for handoffs and capital planning, and avoid the common trap of "checkbox testing" that creates false confidence. Michael shares concrete examples from commercial properties—what went wrong, how teams diagnosed hidden dependencies, and cost-effective fixes that improved uptime. The episode gives property owners, facilities leaders, and IT managers a repeatable approach to validating resilience: what to test, when to escalate, and how to document results so teams can act quickly during real incidents. Practical, non-technical, and designed to fit within short maintenance windows—this is resilience you can prove, not hope for.
