Norms, gender and collaboration in proptech Here, an engineering approach to norm criticism is used to study a male-dominated interdisciplinary digitization project in the area of prop tech. In property automation (prop tech) the participants are in principle exclusively men, and thus the platforms and program development that will be the basis for all prop tech development are coded in a male context. There are also major challenges, as in most interdisciplinary groups, where the balance of power is often skewed through different norms. The project has mainly addressed challenges due to the interdisciplinary groups, while the gender perspective has been given less focus. The focus on norms has been assigned a full work package, with a similar budget as the other work packages focused on other areas and the norm work package has interacted very closely with all parts of the project, including the more technical ones. In this way, the norm critics has created a platform of its own in the project, based on how a norm critical analysis could be offered to help other work packages in their tasks. Based on the work on norms; discussions, workshops and surveys have been supplemented with interviews, in close collaboration with other work packages. Through the norm-critical analysis, different groups, both within the project and in the industry around prop tech, have been identified. Differences between these groups relate to understanding of different types of technology, priorities, communication and balance of power. Norm criticism has been a way of supporting the entire project in both the expansion of business models and interaction between the various scientific areas that are part of the project. The norm criticism has been well received by the project group and many are aware that the industry is facing a change that requires new ways of thinking, new business models and new collaboration models. There is a new awareness in both the conversations within the project and the surveys and interviews based on the understanded need to see multiple perspectives. This awareness has also been used to broaden the business model. The understanding that it is more difficult to see the order of power for those who belong to the prioritized group has also increased. At the same time, we see a large effect of personal, or corporate, interest in norm criticism, which strongly influences how respondents react to the questions about norm criticism. The project shows that the method of using norm criticism in collaborative processes between different groups has been successful.
