“We use this term for people who have the capabilities to understand complex situations, to cope with the unusual, to identify the right problem in order to solve it and who are able to take decisions keeping in mind a vision for the future” (Brigitte Daniel-Allegro and Gary Smith 2016). “The chemist uses their understanding of chemical elements when they interact with chemical substances. Likewise, in the future the systemist will use their understanding of systemics when they manipulate and transform systems” (Gary Smith 2020)
