The study is also demarcated to knowledge types and competence. The method of obtaining information consists of 9 interviews that investigates 4 different projects that have used CLT framework. The result of the interviews have been put together into the result and then analyzed. The results have been compared with past studies from the Theoretical frame of reference, which is focused on knowledge and competence. The study is focused around 3 knowledge types which is domain specific knowledge, procedural knowledge and general knowledge. One of the problems that was recurring was the lack of piercings in the CLT elements.
