This paper discusses productivity in relation to tacit knowledge (which in the paper is regarded as skills, experiences, competences and attitudes) and domain complexity. The study is based on five very different case studies; three studies are conducted in Den¬mark, China, and the Czech Republic and these studies are particularly studying knowledge transfer when moving manufacturing facilities to a new location. Two studies investigate operation and automation of oil and gas production in the North Sea. Semi-structured interviews, surveys, and observations are the main methods used. The paper provides a novel conceptual framework around which manage¬ment will be able to generate discussions about productivity and the need for learning programs when considering changes in the complexity of a domain.
