A method of monitoring the manufacturing status of a machine comprises the steps
of assigning a machine identifier to a machine comprised of one or more components,
the machine to be manufactured at one or more production stations, wherein each
one or more production stations is assigned a production station identifier, inputting
the machine identifier into at least one memory of a first computer, inputting
a unit control identifier for each one or more component, wherein the unit control
identifier is linked to the production station identifier where the unit control
identifier is input, inputting defect information for each one or more component
into the memory at an inspecting station, wherein each inspecting station is assigned
an inspecting station identifier, so that the component information and the unit
control identifier are linked to the inspecting station where the defect information
is input, linking the stored unit control identifier, and the stored machine number;
and outputting defect information.
