Is Good Design Replicable?

Joshua Porter of bokardo.com asks "Is Good Design Replicable?"

I ask because many people seem to think process is the key to good design. For example, on almost every thread of the IxDA mailing list, there is an argument about which design methods are better…are personas better or is genius design better? What method or process should we be doing to get the best possible product? The implicit assumption is that if you perform some particular UX method then you’ll produce consistently better design: the right process = the right product.

So, the obvious question to ask is: Is there evidence that someone following a certain process produces great design every time?
