The present invention warns an operator of failure to properly use an indication device within an assembly line for producing articles of manufacture. The present invention includes a detector, coupled to the indication device, for detecting application of the indication device to a work piece within the assembly line. In addition, the present invention includes a timer, coupled to the detector, for timing a measured time period from a first time point when a prior application of the indication device to a first work piece is detected within the assembly line. The present invention further includes a warning unit, coupled to the timer, for generating an alarm signal if the measured time period is greater than a predetermined time period and if a subsequent application of the indication device to a second work piece has not been detected within the measured time period. The present invention may be used to particular advantage when the indication device is a marker that is used to make a mark on an automotive part to indicate completion of testing the automotive part or to indicate inclusion of a predetermined part to the automotive part. The alarm signal generated by the present invention reminds the operator to use the indication device for each work piece within the assembly line.
