Now when I’m asked, “What's the most effective way for people to share their tacit knowledge?” I always think of Hans and the answer I give is: “Tacit knowledge needs to be shared through conversation.” My reasoning is as follows.
Our tacit knowledge is drawn from our experience as well as our years of study and is stored in bits and pieces in our brain, that is, it is not stored as answers or explanations but as fragments. What we call “tacit knowledge” is the human ability to draw on those fragments to construct a response to a new problem or question.
Tacit knowledge is particularly useful when we are faced with a complex problem. By complex I mean a problem that does not have a factual, right or wrong answer, for example, "What architectural design would best fit this physical space and meet the needs of the client?" or “How would you stop an oil leak 5000 feet under water?” When an expert like Joachim faces a complex problem he brings together those bits and pieces of his experience and study that are relevant to that specific problem situation and puts those together to form a solution. Because he is embedded in the situation he knows the context and the end goal. In bringing together those bits and pieces that are in his head, he conducts, what Don Schon would call, a “reflective conversation with the situation.”
