Software quality is more the result of a system designed to produce quality, and not so much the result of individual performance. That is: a group of mediocre programmers working with a structure designed to produce quality will produce better software than a group of fantastic programmers working in a system designed with other goals.
This talks about development, but I believe it applies equally—if not more—to design.
And this is very insightful:
Instead of spending tons of time and effort on hiring because you believe that you can “only hire the best”, direct some of that effort towards building a system that produces great results out of a wider spectrum of individual performance.
