Synthesis is a creative and mysterious process in which a chaotic array of concepts, what might be called a mess, is cognitively 'engaged' with a problem domain to produce as many interpretations as can validly be derived for effective decision-making purposes. The benefits of engaging concepts into a mess are that it allows the problem to be viewed through multiple lenses simultaneously, which affords a holistic vantage point for richer problem interpretation. By deliberately shifting the underlying concept held by actors and provoking the movement of concepts, better interpretations might lead to more useful decision making. Although research has discussed the possibility of using synthesis through case studies, we argue that there is a need to formally develop methodologies in this area for the purpose of fostering and solving complex problems. To demonstrate this, we provide a speculative case study to illustrate how this approach may be usefully applied.

The concept of a wicked problem (Ackoff, 1978) is a unique and troublesome one. Liebl (2002) notes that when trying to understand wicked problems one must accept that they are messy. We must adopt the 'moving target' metaphor. In dynamically changing environments, unstructured problems cannot simply be cleanly nailed down to a given set of alternatives or be reduced to a significant and easily managed cognitive model (Van Bueren et al., 2003). Instead, we must rely heavily on actors' conceptions and subjective interpretation of the problem to give it meaning (Landry, 1995). According to Leibl, a problem arises when the dynamic concepts used to form interpretative schema interact in an ill-structured or 'wicked' context with unpredictable consequences. In essence, (2005) somewhat aptly calls these problems wicked in the sense that they are seemingly impossible to interpret, much less act on effectively due to the difficulties of reaching a shared understanding on the meaning of the problem. A range of problem structuring methods have arisen as a response to this issue (Mingers and Rosenhead, 2004;Mingers, 2011;Shaw et al., 2006).More fundamental than constructed methodologies is the human instinct for creativity and ingenuity when trying to solve problems. De Bono (1970) highlights this as lateral thinking, a process by which we think sideways, perhaps in unorthodox ways about problems to gain new insights. This speaks to the idea of 'synthesis' as an alternative way of approach wicked problems. We ask, would there not be considerable benefit to have a softer, alternative approach when trying to solve 'messy' problems? That is, if we are to make traction in wicked problems, would not the analytical approaches of the past lead to s...
