Launching a new product involves the efforts from design development and market development, which requires cross-functional collaboration. When the novelty of a project is high, it would be rather difficult for co-workers to cross boundaries since the shared knowledge is relatively limited. These knowledge barriers might lead to communication problems, which decrease the efficiency of collaboration. The process of collaboration requires certain facilitation to bring up the team performance. Some artifacts are created to help design engineers to present their research outcomes from new product development, such as prototypes, documents and technical notes. However, these artifacts still seem insufficient to support cross-functional collaboration. Based on the upper mentioned problem, this graduation project aims at finding a design solution to help design engineers to “sell” their ideas or designs to internal stakeholders via artifacts, thus to reduce the barriers in collaboration. “Selling” ideas and designs is a process of sharing understanding between different disciplines. The main approach of this project is research through design: testable prototypes were built to reflect on the finding of research. The project started with a contextual understanding, followed with a literature search and a context study. A cross-functional team was selected as the target for the research. The grounded theory method was used for data analysis. According to the findings of literature study, there are two approaches for knowledge integration in R&D collaboration. One approach is to traverse knowledge by transferring, translating and transforming it, thus the individuals with different expertise could share and assess each other’s knowledge by crossing knowledge boundaries. The other approach is to transcend knowledge instead of clarifying the knowledge differences. Actions are taken to minimize the knowledge difference and aim at finding solutions for design problems. Thus the new product development could be done without understanding tacit knowledge in depth. The studies on the R&D team showed that telling good stories of their research outcomes is quite essential during new product development. To convince clients, design engineers need to show how they take the feedback from clients into account, and how they manage risks to ensure that the concept could be launched in the market successfully. In addition, besides knowledge barriers, creative tension also exists among stakeholders. Design engineers have to face various choices and deal with uncertainties. Based on the upper mentioned findings, six design directions were generated, which would be further explored in the design phase. To better guide the design phase, a design statement was generated, which is to design an artifact/ artifacts that help R&D team to better demonstrate their research and development process, thus to improve the communication among stakeholders and working performance of the team. Increasing interactions and presenting rich and clear information in the new product development process are the two focus of the final design. Further context research was conducted to narrow down the design direction. In the end, a system design was delivered. There three main usages of the system, which are rich research outcome demonstration, flexible prototype presentation, and facilitating effective and direct discussion. The system design consists of four items: the Container A, the Container B, the Carrier and the Wall rack. The Container A is a paper box for storing finished prototypes. The Container B is used as a temporary storage for the prototypes that are still in use. The carrier is designed for users to carry prototypes around in a decent and safe way. The wall rack is designed for organizing prototypes storage and presenting research outcomes. The design could encourage the users to present and make use of the research outcomes, and noticeably, it could bring different roles involved in the project together. Furthermore, by gathering and organizing information, design engineers could be aware of the situation and have a better understanding of common knowledge.
