With the help of XR tools, globally dispersed teams can collaborate remotely in shared virtual environments, reducing the costs associated with physical prototypes and travel while benefiting from including stakeholders from various backgrounds in their process. Integrating digital human models in these virtual environments allows for collaborative design interactions and possibilities for performing ergonomic design and assessments. While screen-based tools are the standard for these evaluations, the inclusion of XR tools can augment current screen-based tools to improve the evaluation of ergonomics and the assembleability of components with digital human models. This study describes an implementation model for collaborative assembly simulations, ergonomics assessments, and reviews in a shared virtual environment with XR and screen-based tools. A pilot study with fifteen participants was designed to compare a Swedish/Chinese vehicle manufacturer's approach to simulating and analyzing assembly designs with the collaborative virtual environment model developed. The results show that teams collaborating in a shared virtual environment performed better in user experience, the feeling of presence, and precision when detecting ergonomics and assemblability issues.
