This examination has been made in cooperation with Jernhusen which is an estate company owned by the government, with estates along the railways in Sweden. This assignment is to help Jernhusens business area Projektfastigheter with their experience feedback, which is to-day almost absent. Business area Projektfastigheter has the task of supporting Jernhusens three other business areas with skills and resources for the estate projects that Jernhusen runs. Jernhusen must become stronger with the collecting of experiences and as a business because of the Liberalization of the railways, which leads to a more competitive market. A tool for this is successful experience feedback.The concept of experience feedback is to gain experience across a variety of cases, where individuals and/or groups can chose situations with relevant similarities and differences with current case.
