In design controls, there is the DID and DSD documents. DID is design input and gives a broad description of the product (ex, “red knob”), whereas the DSD is design specification and gives a very specific description(ex, “red knob 3cm in diameter dyed with red #5 from Vendor x with a tolerance of 0.001cm”). What do you think the advantages and disadvantages are of each document and why are they both necessary?
