Abstract
This paper examines how a deeper understanding of procedural justice and interactional justice can enhance the effectiveness of causal mapping workshops using Group Explorer (R) software combined with the Decision Explorer (R) tool. A dual facilitation model is outlined that explicitly links the determinates of procedural justice and the key elements of interactional justice to the stages of causal mapping workshops. This model serves to illustrate how the participants' voice in group workshops using causal mapping is strengthened, producing an authentic outcome that more accurately represents participants' thinking. Enabling the determinants in the model supports the dimensions of procedural and interactional justice, ensuring these more authentic outcomes. A link between these determinants, dimensions and the workshop process is confirmed through qualitative and quantitative analysis. The qualitative analysis draws on causal maps created with relevant concepts/ statements, highlighted to illustrate this more authentic voice. The quantitative work analyses responses to a post-workshop questionnaire using scale reduction techniques and looks for significant relationships between participants' voice and the determinants of procedural justice, interactional justice and the causal mapping approach adopted.
