In this thesis I show how cultural changes in a Danish slaughterhouse leads to an informal Community of Practice. The employees act independently, flexible and dynamic in accordance with the technological challenges they face to insure an effective production. Because of these actions, the employee's challenge the formal tayloristic structures in which the managers seek greater control. The thesis is based on Action-research in which the Sensemaking Model is utilized based on Karl E. Weick's theory of meaning making and Chris Argyris's theory of organizational traps. In collaboration with Danish Meat Research Institute three workshops involving interdisciplinary workgroups were held and the results are evaluated as to whether this method can be used as consulting service.
