Design is shaping the world. Many examples illustrate that designers can change the world for the better. We are entrusted with more and more complex challenges and develop ever-novel approaches. Nowadays a plethora of design discipline exists and it seems fitting to clarify what it is that unites the designers today to then discuss how we can connect design to other fields better in order to maximise the impact of our work. One field that is proving a particularly rich complement to design is Systems Thinking, which essentially studying the interdependencies between elements in complex structures. While design thinking is a bottom up approach, systems thinking can supply the big picture context. Combining the two allows us to be more targeted in how we apply our design efforts.
