[Rickertsen2]

If we had a one year build period i might be able to see some logic in the restrictive school of thought. I think that by forcing teams to reinvent the wheel , rather than buying one off the shelf, you cause them to waste time on unimportant and mundane details. Rather than engineering a cool new carriage as a whole they are faced with figuring out how they are going to make wheel spokes. A greater repertoire of available parts lends itself to an exponentially greater wealth of new ideas by allowing teams to focus on what is really important.
