This document discusses skills for knowledge brokerage related to complex phenomena. It notes that for complex problems, the answer is often unclear and there are diverging views. It presents a "complexity cube" that describes problems as tame, messy or wicked based on uncertainty, interdependencies and divergence. For wicked problems, the focus is on facilitating continuous joint sense-making of emergent issues. For messy problems, the focus is on bridging different evidence and users/producers. For tame problems, the focus is on supplying evidence. The document emphasizes understanding the nature of the problem and selecting the appropriate knowledge brokerage approach, as well as skills like managing diverse knowledge, dealing with uncertainty, and designing joint sense-making processes
