Sharp End vs Blunt End

CORE DEFINITION

Sharp end and blunt end are the two halves of organizational accidents. The sharp end is the frontline operator, the pilot or nurse, whose action directly touches the system and who typically triggers the incident. The blunt end is the layer of managers, designers, and regulators far from the scene, whose decisions set the conditions under which the sharp end works. The practical use is in how to apportion blame: punishing the operator only removes the last straw, while the environment that made the error likely stays. Change the operator without changing the environment, and the next operator repeats the accident. Qualification: sharp-end errors are real; the claim is that they are the trigger, not the cause.
