When we deal with large scale systemic change, it is valuable to develop the skills to recognise true complexity so that we can approach it appropriately. In Chapter 2 of the book “Large Scale Systemic Change: Theories, Modelling and Practices, Nova Publishers, New York, NY. (2016)” Jan Hendrik Roodt of StoneToStars Ltd covers a broad introduction to the topic of complexity, linking it to systems theory to deal with turbulance and uncertainty in the world today. The Chapter is one of four that sets the theoretical and philosophical tone for a book that covers a range of methods and applications. Jan Hendrik has been working in the domain of complex problems since the late 1990s and has experience of addressing it in technology and policy rich environments.
