On May 26-27 2008, Wageningen International and Learning by Design organised an innovation dialogue on ‘navigating complexity’. It sought to articulate insights from the complexity sciences and systems thinking. And examine how these could reshape assumptions about the design, monitoring and evaluation of development work. This event was born out of a growing sense of urgency about the dilemmas facing the development sector. Development organisations are guided by protocols that are essentially based on a linear approach to meeting objectives and on processes that are assessed in comparative isolation of the dynamic context. Many efforts work with limited and out-of-date insights on their operational contexts. The consequence for those managing development efforts is a reduced capability to guide strategic engagement, which affects effectiveness. Any planning process is based on many assumptions. Some of these assumptions will be quite predictable, while others may be but wishful thinking.
