Abstract: In the design processes, designers make decisions by intuition, experience, or support tools. In the case of design for changing behaviours, designers evaluate their strategies or artefacts using tools derived from other disciplines; therefore, there is no framework for evaluating alternatives in the early stages of the project process in this area. This study presents an evaluation tool formulated from heuristic design principles to change behaviours, which were validated through a literature review and tests in design projects for changing behaviours. The results indicated that the designers, when evaluating their ideas with the proposed tool, made decisions focused on generating and adjusting their ideas to these principles. During the tests, participants did not select or reject proposed ideas; instead, the tool served to reflect and adjust the design proposals to the design theories for behaviour change implicit in the heuristic evaluation tool.

Keywords: behavioural design; design processes; design principles; decision-making; heuristic evaluation.
