Job aid

Performance support systems are modern job aids.

 A job aid is a set of instructions, diagrams, or similar methods available at the job site to guide the worker. Job aids work particularly well on complex jobs that require multiple steps, or where it’s dangerous to forget a step. Airline pilots use job aids (such as a checklist of things to do prior to takeoff). GM’s former Electromotive Division gave workers job aids in the form of diagrams. These show, for example, where the locomotive wiring runs and which color wires go where.
