The construction industry in Sweden has in the past 50 years had a low progress in efficiency. With a greater competition from construction firms from other countries, it is necessary to maintain the profit for Swedish construction firms. This is possible with a higher feedback of experience. This diploma work thesis examines how the two construction companies NCC and Skanska in Uppsala, Sweden handle experience feedback from previous projects and the extent to which the experience is spread and used in future projects. In this work, we examined directorial documents to see how employees shall work with feedback. Written protocols and reports were analyzed to see the extent to which employees comply with established guidelines. Finally, interviews have been conducted with project managers to get their opinions of how work experience feedback is performed. The conclusions of this diploma work are that employees in both NCC and Skanska comply in varying degrees with the established guidelines due to ignorance. We have also concluded that protocols of meetings and written reports are distributed in a low extent as well as the lack of collecting and store them in a central database. If experience feedback would occur to the extent which is desirable, it would leadto a reduced risk of errors during production, which eventually leads to reducedproduction costs.
