The world has become increasingly networked and unpredictable. Decision-makers at all levels are required to manage the consequences of complexity every day. They must deal with problems that arise unexpectedly, generate uncertainty, are characterized by interconnectivity and spread across traditional boundaries. Simple solutions to complex problems are usually inadequate, and risk exacerbating the original issues.

Leaders of international bodies such as the UN, OECD, UNESCO, and WHO and major business, public sector, charitable and professional organizations - have all declared that systems thinking is an essential leadership skill for managing the complexity of the economic, social and environmental issues that confront decision-makers. Systems thinking must be implemented more generally and on a wider scale, to address these issues.
