The topics of risk and uncertainty are often featured in the project management literature. Uncertainty is particularly prevalent: we grapple with uncertainty when dealing with the unknown; we acknowledge that we increasingly live in a volatile, uncertain, complex and ambiguous world replete with limited knowledge and uncertain and unpredictable patterns; we endeavour to acquire resilient traits that allow us to adapt and adjust; and generally, we seek more agile approaches in order to respond to a world that seems to change faster than we are able to adapt, or learn. Looking through recent contributions, one might almost observe that the obviation of uncertainty is an increasing obsession of the human race; yet, uncertainty itself, which appears to be an abundant feature of our creative landscape, is scarcely addressed explicitly in our recipes, prescriptions and bodies of knowledge.
