The building industry has issues with efficiency and waste where only 3-20 % of the activities in a process are of value. The production philosophy Lean, has been shown to reduce waste and also increase efficiency. Lean derives from Toyota Production System and involves, among other things, reducing waste, standardizing processes and continuous improvements while maintaining focus on the customer. To value how Lean a company is, there are different Lean maturity models that can be used. For industrialized housing there has been a lack of a maturity model which can be used to evaluate their Lean maturity. Therefore, the purpose of this study is to develop a Lean maturity model within industrialized housing with production in focus, where developing opportunities are shown for continuing work with Lean. This study has developed a specific Lean mature model for industrialized housing (LMI) where categories that are relevant for evaluation of the maturity level have been developed. Test of LMI from theory have shown that it works. The companies participating in the study that have an ongoing Lean work consider the categories relevant and accurate, with small changes to function entirely. For the study it can therefore be concluded that an evaluation model for Lean maturity in the industrialized housing can appear according to the reports descriptions. The companies participating in this study have in multiple categories reached different levels. In common there is a lack of methods for distributing and collecting experiences. Furthermore, LMI indicates that Swedish industrialized housing in general have extended understanding about Lean. This can be compared to traditional on-site construction where the efficiency and Lean maturity still in general can be considered low. Lean can therefore be seen as a success factor with waste and continuous improvements in focus. The conclusion of this study shows potential improvements within experience feedback amongst the companies working in industrialized housing.
