More questions pertaining to correct data modeling of inspection-only manufacturing tasks

[Christian Carlow]

After pieces are received into inventory they go to an inspection dept 
that determines the number of good and bad pieces.  Since this 
inspection dept does not do any actual manufacturing to the part I 
assumed the work should be defined as the first step of the first 
manufacturing process that is supposed to occur.  Using this model is 
fine when manufacturing process exists but when the manufacturing 
processes are contracted out or the part is bought ready to be sold and 
only the only work required is the inspection stage, this model doesn't 
seems sufficient.  Does this mean that inspection-only tasks should also 
be modeled as routes with BOMs (technically finished goods) received 
being converted to the inspected versions of it? How would I account for 
the inspection-only work which may result in the rejection of the 
received finish goods?
