Since part numbers are entered by hand over and over again into computer
systems the key is to use the smallest number of digits possible.
Part numbers should not attempt to define the part.
I would suggest a 6 digit system xxyyyy where xx is a gross identifier and
yyyy is just a sequential number within the xx class.
Do not use dashes or periods in the part number - that is just one more
keystroke to enter.
Do not use Alpha characters - you should be able to enter the part number
with a key pad for speed.
