Efficiency vs/and Creativity

Having read considerable literature on 'creative process' mapping, sometimes I wonder, how should organisations balance the equation between Efficiency( viz. results) and Creativity?

• Will relentless emphansis on efficiency make a company less creative?
• Can you set up a process around 'Innovation' , which by its very inherent nature is a disorderly process?
• Can a 'creative mindset' be used to hard-wire a company( on processes)?
• How to decide between 'sameness' ( as demaned by quality process Six Sigma) and 'uniqueness' (as valued by Creativity)?

While process excellence demands precision, consistency and repeitition, innovation calls for variation , failure, and serendipity.
