Obsessive Optimization – When you have 5000 employees, or $500 million in revenue, fractions become significant. A .5% increase in revenue is not a small thing, it’s a big thing. It can be bigger than many companies’ entire revenue. And as companies age the culture looks to optimize and refine, eventually to a point where the good things that led to all the success have been whittled away. Managers at big companies often have more incentives to minimize costs, than to find new business or develop new ideas since minimize costs or optimizing an existing process are cheaper wins that show results in the short term. In an optimization centric culture, the myopic love of short term wins can makes long term improvements, which often require short term sacrifices, hard to pull off.
