There is a need for efficient experience feedback in the construction industry, which encompasses companies that use a wide spectrum of on- and off-site production methods to produce (inter alia) roads, bridges and railways, as well as low- and highrise buildings. The rationale for developing and implementing methods for experience feedback is well documented, and regardless of the choice of production strategy common denominators are needs to recognise defects and to apply a continuous quality improvement program that incorporates learning from mistakes. The purpose of this paper is to present ongoing work regarding experience feedback, with the ultimate aim to close the feedback loops in off-site housing sales, design and production. An indoor production process at a Swedish housing company is probed.The investigated company utilises off-site module manufacturing, a production form with a 15 % market share among professional clients in Sweden (recurrent clients purchasing commercial and multi-storey buildings). This production form appears to be well-suited for implementing experience feedback, since control is already required in the production process. Based on a literature review and case examples a model for experience feedback is proposed. The feedback model is executed in a logical control structure with four levels: (1) plan and learn, (2) capture and assign to targets, (3) analyse and prioritise, solve and assess, (4) implement and use feedback. Theoretical considerations and empirical data show how analysis of error-detection can enhance possibilities for prioritising improvement actions as well as identifying feedback targets.
