Systems Thinking is an approach used to address complex real-world problems. According to INCOSE-UK, it is ‘an essential skill for Systems Engineers … and provides a key intellectual underpinning for Systems Engineering’. Unfortunately, the literature associated with Systems Thinking can seem dense and more concerned with theoretical matters than practical application. This presentation seeks to cut through the academic noise and pinpoint the crucial features of Systems Thinking for Systems Engineers.
There are four essential things that Systems Engineers need to know about Systems Thinking. First, that it developed as a complementary approach to science because the scientific method struggles in the face of complexity. Second, Systems Thinking has been successful in developing a range of systems methodologies (systems engineering, system dynamics, the viable system model, soft systems methodology, critical systems heuristics) that can engage with different aspects of complexity. Third, it is necessary to understand the strengths and weaknesses of these different methodologies and to use them in combination to bring about systemic improvement. Finally, such ‘Critical Systems Thinking’ requires a radical reorientation of mindset on the part of Systems Engineers.
