Over the years in the power sector, I've learned that quality is rarely about the equipment.
The transformer passes its factory tests. The relay is certified. The software is the latest release. And still, the failure comes.
The data supports this. In WECC's report on 2024 protection system misoperations in the Western Interconnection, incorrect settings, logic and design errors accounted for 41% of cases. Relay failures accounted for 14%.
The weak point is rarely the device. It is the process around it: the requirement nobody validated, the setting file nobody compared, the test that checked the parts but never the system.
That is why I see quality in mission-critical energy as a management system, not an inspection step. It starts at planning and runs through supply chain, engineering, commissioning, operations and the boardroom. Frameworks like ISO 9001 build on a simple cycle: plan, do, check, act.
Quality is not what we inspect at the end. It is what we build into every step.
