The construction process includes many steps, phases and moments from the idea until the product is completed and handed over to the customer. Construction companies usually divide their work into several projects where the employees work in parallel project teams.   In this report, a study together with NCC Hus in Uppsala has been performed in order to improve their return of experience. The main goal with the study is to identify the extent of the need in the process of returning experiences between the organizations in the production stage. The report is based on interviews and a case study, together with theoretical background to create an idea of the situation, the need and possible improvements that applies to return of experience.   In the report we have come to the conclusion that the employees at NCC Hus in Uppsala are positive to spreading their knowledge and experience. The individuals in the organizations has a lot of knowledge and experiences, but there are no structured methods for when and how experiences should be collected and documented. The study shows that the extent of the need consists development of reference sheets that facilitate oral communication and documented experience regarding work preparation, work environment and choice of materials. The study suggests that the documentation should be kept simple and not superfluous, and that the information should be easily accessible and quality assured for the benefit to be valuable. In summary, through involvement and structured systems, the process has great development potential.
