Know-how and workplace practical judgement

In workplace situations of all kinds novices are transformed by experience of practice into highly proficient practitioners. How are we to understand this change which appears to be as much a qualitative one as it is a quantitative one? This paper argues that the available resources for understanding the informal learning that occurs during the course of successful workplace practice are somewhat limited. Theories about know-how are criticised for shedding little light on this topic. The notion of tacit knowledge is also rejected as unhelpful. The development of judgement is proposed as a more promising way to understand the phenomenon. A consideration of four main dimensions of contextuality is used as a lead into an account of eleven key features of workplace practical judgement.
