Many building incidents start with a single question: who owns that system? This episode shows how to build a living technology ownership map that prevents outages, speeds repairs, and clarifies vendor responsibilities. Host Alex Morgan interviews Michael Harrington to unpack common handoff failures—unclear maintenance boundaries, undocumented changes, and patchy vendor coordination—and a practical, lightweight framework owners can adopt today: asset-first mapping, clear RACI entries, tiered escalation paths, and a maintenance cadence tied to capital planning. Michael shares real-world examples where a simple ownership map cut outage resolution time, reduced tenant disputes, and made capital planning more accurate. Listeners will leave with a three-step starter plan, examples of what to include (not exhaustive checklists), and guidance on keeping the map current without creating extra bureaucracy.
