Engineers like to apply the second law of thermodynamics to chemical processes and power generation cycles. However, it has some useful lessons for everyday life since it can be paraphrased as ‘whenever you organise any process expect some disorder, or entropy to be generated’, so a shrewd person plans for disorder and designs in a bit of slack or redundancy.
Bob and I gave an example of this in our book, ‘The Entropy Vector’. We pointed out that if you plan your flight schedule to use all of the available gates at an airport then you will have unhappy passengers when flights are delayed, unless you plan for buses to unload planes parked away from the terminal. European airports tend to be good at this whereas US ones tend to leave passengers in planes that are unable to dock at the terminal.
Our example was inspired by frustrating experiences when we were writing the book. A more topical and important example was raised by Mark Winston in the New York Times on July 14th, 2014 in reporting the importance of bees to farming. His research team found that crop yields were maximised when large acreages were left uncultivated to support wild pollinators. He postulated that a variety of wild plants means a healthier, more diverse bee population which will be more active in the planted fields next door. Their numbers were startling with profits more than doubling for farmers that left a third of their acreage fallow. Winston highlights that this contravenes conventional wisdom that bees and fields can be micromanaged.
This seems like reinventing the wheel because I remember being taught about the importance of crop rotation, including a fallow period, in my ‘middle’ school geography classes. Oh dear, now I am showing my age.
The bottom-line is don’t micromanage. Allow for a bit of inefficiency, not too much of course or your competitors will get ahead! It’s a question of balance.
