Make internalised mental models tangible, explicit and externalised using collaborative modelling techniques like Event Storming or Domain Storytelling. This creates a shared, physical artefact that the team can inspect, question, and rearrange together. It shifts the focus from critiquing a person's idea to collectively refining a shared model.
Examples
The team uses sticky notes to map out a business process, making everyone's assumptions visible. This allows them to point at specific parts of the external model and discuss disagreements concretely, rather than abstractly debating their internal views.
