Trondheim Kommune Mestringsteam has several EMDR certified therapists that use the EMDR method to help people in vulnerable life situations with trauma treatment. During this project Co-design also referred to as participatory design has been used to manifest the therapist's knowledge into the already used material and new materials. A lot of theory for knowledge acquisition and how our brains work in connection to cognitive load and cost was used as basework for design decisions to strengthen the creative ideas and visualizations of the therapists.

The scope of the project was framed in an ecosystem, because of the qualities of the stakeholders and their interactions with the artefacts. As a learning system the value of the whole system is bigger than what each artefact contributes alone. Meaning, by interacting with all the artefacts the stakeholder gains more because of the synergies for learning between the elements. 

From Co-design sessions, design workshop and usertesting the product was shown to match their mental model of EMDR and all the stakeholders had better understanding and flow in their conversations with clients. The last version shown on the side is a compromise between all stakeholders and design interests. This project showed how an artefact could be a boundary object for knowledge exchange between designers and a focus group.
