This paper explores the integration of causal pathway diagrams (CPD) into
human-centered design (HCD), investigating how these diagrams can enhance the
early stages of the design process. A dedicated CPD plugin for the online
collaborative whiteboard platform Miro was developed to streamline diagram
creation and offer real-time AI-driven guidance. Through a user study with
designers (N=20), we found that CPD's branching and its emphasis on causal
connections supported both divergent and convergent processes during design.
CPD can also facilitate communication among stakeholders. Additionally, we
found our plugin significantly reduces designers' cognitive workload and
increases their creativity during brainstorming, highlighting the implications
of AI-assisted tools in supporting creative work and evidence-based designs.
