The Swedish School of Textiles is an international resource centre with more than one thousand students. The Institution did not only grow massively in many last years, but had also grown in an uncoordinated way. Some staffs now do the same tasks; therefore it wastes a lot of time for discussion which job has already been done or who should do which job. In addition, the organization has the functional design with responsibilities for some tasks of each staff, therefore if some staff gets ill, his or her tasks are still undone. Everything is focused on one customer (the students) but more customers have to be considered. The Theoretical frame work are ISO 9001:2000 a Quality Management System that is based on processes and process mapping. In order to achieve process mapping, several Quality Management tools have to be used as tree diagram, affinity diagram, and interviews. The process mapping is suitable for visualization the administration’s current work flow and clearly definition the interfaces of working of the administration staffs. The results are process mapping of the main processes and one level down in the subprocesses. Consequently, the thesis would help the administration department for clearly defining their processes, including suggestion of continuous improvement as being presented in the suggestion part.
