Our world is facing many dire societal problems. These problems are not simple problems—they are systems of problems, or what Herb Simon called “wicked problems” and Russell Ackoff simply dubbed “messes”. To respond to these demands, the discipline of design needs to adopt a larger, more holistic view of problems and the solutions that might be developed to address them. My work on product-service ecologies helps to embrace systems thinking to better design for the world in which we live.
