Operational resilience

How to build it, deliver it and prove it

Operational resilience has moved from IT teams to the boardroom. It is not a project with an end date, or something to plan for. It is a discipline shaped every day in how technology is run, managed and improved. In this four-part video series, Triangle leaders share their perspective on what operational resilience means in practice for enterprise organisations in Ireland. From the boardroom view to the engine room detail, each video examines a different layer of how resilience is built, maintained and proven.

Episode 1

Resilience is how you operate

Paul Flavin, CEO, Triangle

Paul Flavin, Triangle CEO, outlines why operational resilience is increasingly something organisations need to evidence. He explores the shift from defence-only thinking to a model built on people, processes, platforms and controls. He explains how resilience is built day-to-day through the operational details that decide whether disruption is absorbed or amplified.

Episode 2

How managed services delivery impacts resilience

Brendan Healy, Director of Services, Triangle

Brendan Healy, Triangle Services director, explains why resilience depends on how technology is run, managed and improved. He looks at what “end-to-end resilience” means in practice, where proactive, accountable service delivery connects protection and recovery, and why contract economics should not get in the way of doing the right work.

Episode 3

The everyday discipline of building resilience

Liz McGing, Head of Managed Services & Brendan Healy, Director of Services, Triangle

A conversation about how delivery discipline translates into measurable outcomes. Brendan is joined by Liz McGing, our Head of managed services, to discuss the operational discipline behind resilience. They cover proactive monitoring and problem management, how critical incidents are handled in practice, and the governance that helps customers retain operational resilience as priorities and platforms change. Liz shares specific results, including a 14% decrease in incidents year on year.

Episode 4

The role of the architect

Ciarán Garvey, Director of Technology & Brendan Healy, Director of Services, Triangle

A conversation about how architect continuity from design through to operations strengthens resilience. Brendan is joined by our Director of Technology Ciaran Garvey to explain why architect continuity matters. They discuss how keeping senior architectural oversight from design through operations supports smoother transition, stronger service ownership, and a more measured balance between innovation and operational resilience.

What does operational resilience look like in practice


A useful test is what happens after the incident is resolved. In our client success story, a leading Irish food distribution company partnered with Triangle after a major incident to modernise infrastructure and strengthen day-to-day IT operations. The engagement evolved into a 24x7 managed service, with consistent processes for monitoring, patching, incident, change and capacity management, designed to keep critical services resilient as the environment scaled and changed.

“If resilience matters, it needs to be built into how the environment is run: assumed breach thinking, tested recovery paths, and operational habits that stand up under scrutiny. If you would like a second view on your approach, we can help you sense-check it.”
