It was a taxi driver in London who give me the idea whilst we were chatting about “Sherlock Holmes”.

I mentioned one of the Sherlock quotes “we all see, but some of us observe”

He mentioned in France they have a word for that:

System D is a manner of responding to challenges that requires one to have the ability to think quickly, to adapt, and to improvise when getting a job done.

The term derives from the French term “Système D”. The letter D refers to any one of the French nouns, basically, it refers to one’s ability and need to be resourceful.

System D is a shorthand term that refers back to the French word dé brouillard, one who is skilled or resourceful at handling any difficulty.
