The Aggregation of Marginal Gains

In 2010 Dave Brailsford took over as the General Manager and Performance Director for Team Sky (Great Britain's professional cycling team). To take the team to new heights, Brailsford introduced the team to a concept that he referred to as the "aggregation of marginal gains." The concept can be summed up as improving every facet of training by 1 percent so that collectively those marginal gains could equate to a larger performance improvement overall. At the 2012 Olympic Games the team dominated the competition by winning 70 percent of the gold medals available.
