Error

a deviation from expected or intended performance that occurs within a system and can be detected and corrected through systematic mechanisms

Why This Is a Definition

This definition establishes the precise semantic boundary of 'error' by specifying it as a deviation from expected/intended performance within systems, with the key differentia being that errors must be detectable and correctable through systematic mechanisms. It distinguishes error from mere failure or malfunction by emphasizing the detectability and correction potential, and it's central to the lesson's core argument that all systems produce errors that must be built into system design.
