Does the operation require recognition of some characteristic to determine what to do with the part?
(e.g. Red light indicates place in reject pile, visual inspection for pre-defined defects)
Can anything be done to resolve this in design of product/process?
Can the part be combined with another part?
Can the part be eliminated?
What can be done to detect whether the part has been incorrectly processed?
Detection device - reset button,
photoelectric eye, limit switch
Lock out subsequent operation if part is incorrectly processed.
Lock out device - limit switch,
Implement operator instructions,
visual aids and training as minimum
Implement Error Proofing
(process/design change and/or
detect/lock out device)
