Performance feedback system

Claim 1

A method of quality assurance and rectification of defects in the process of assembling a vehicle on a continuously moving assembly line comprising the steps of: a. providing a continuously moving assembly line for assembly of vehicles; b. providing assembly stations along the length of the continuously moving assembly line attended by operators who perform discrete assigned tasks on incomplete vehicles positioned on the continuously moving assembly line as the incomplete vehicles pass by, leading to building of complete vehicles; c. providing an assembly data input terminal at each assembly station, with each data input terminal having a plurality of manually actuatable switches corresponding to a discrete assigned tasks of an operator; d. the operators manipulating the switches to indicate successful or unsuccessful completion of discrete assigned tasks with respect to specific incomplete vehicles; e. providing a manually actuatable task completion switch on each assembly data input terminal which, when actuated, indicates to the central computer that all discrete assigned tasks at the associated work station with respect to a specific incomplete vehicle have been completed regardless of whether or not the tasks have been successfully or unsuccessfully completed; f. manipulating the task completion switch at the appropriate time by an operator at an assembly station if all discrete assigned tasks on a specific incomplete vehicle have been completed and communicating this information to the central computer; g. communicating the input data from the assembly data input terminals to a central computer; h. providing a limit switch which is tripped by a vehicle carrier of the assembly line; i. communicating a signal from the tripped limit switch to a sequencing computer; j. scanning data input terminals at the sequencing computer within an assembly zone to verify reporting at each assembly work station; k. determining whether each assembly work station has reported within a predetermined time period; l. generating default input data for a vehicle for any assembly work station which has not reported within the predetermined time period; and m. loading the default input data into the next correct vehicle identification number for each assembly work station.
