A component, assembly of components, interconnection, separations is. .. infallible. ..fallible... 

Much more emphasis is needed on assuring assigned tasks are thoroughly evaluated using a structured process. As humans are fallible, we cannot assume that a job was initially perfectly designed for maximum efficiency or effectiveness. A job may be based on traditional movements and actions that actually contain hidden loss-producing traps for the employees if various job components and hazards come together at a specific future point in time.
