Our IT systems, like much of the modern world, have become increasingly complex and have resulted in different levels of risk. Overlooking key factors or components in these systems can contribute to their failure. It isn’t about knowledge—we know enough to understand how to construct our IT systems.

The origin of checklists goes back to 1935 with an Army Air Corps fly-off that included the Boeing-17 Flying Fortress. The test aircraft’s flight control surfaces were locked to prevent them from flapping in winds when parked on the ground.
