Competence development is an important feature of supplier development projects. To make knowledge about new practices known and adopted by 3^rd, 4- and 5^th tier suppliers, normally SMEs, have however shown to be difficult. This is not only a problem of adequate concepts and resources, but also of didactics, on pedagogical methods. The paper describes and analyses one innovative methodology to spread knowledge and raise competence, namely the KrAft-program. We have followed one supplier development project that was run according to this concept, the Norrgavel case. To illustrate the methodology a case study of the KrAft-group Norrgavel has been carried out. It  is a supplier development project.
