When I sat down to write about sustaining innovations, the word that popped into my mind was “entropy.” While entropy is a scientific term related to the degradation of the matter and energy in the universe to an ultimate state of inert uniformity, it is also used to refer to a process of degradation or running down or a trend to disorder. Entropy is a very real thing in organizations. Practices are implemented and improvements deployed, yet over time, things seem to revert to the way they were always done.
