The purpose of this thesis is to explore how metaphor-based interactions can enhance the behavioural interactions in project environments to deliver better outcomes. It documents the processes and findings from an action research program to investigate the impact of combining metaphor, conversation and reflective practice techniques into a new model, the Reflective Performance Cycle (RPC) to stimulate richer and more productive interactions between project team members. The RPC model was used to stimulate constructive dialogue around behaviours within a team context and participants reflected on the impacts this had on their outcomes and performance.   Interactions based on the RPC model were reported by project team members to develop a better understanding of each other and project stakeholders. Their feedback indicated that facilitating such interactions can contribute to greater trust, leveraging more diverse perspectives and building stronger relationships between team members and also with stakeholders. It is proposed that the use of interventions based on this model can assist constructive dialogue when behaviours are aligned with the situations. Application of the model through team interactions highlights the importance of aligning behaviour with the purpose of the conversation in order to optimise impact and achieve desired project outcomes.   The research participants reported the metaphor based interactions to be simple, fun and intuitive enabling them to be added to team activities to create useful conversations. Implementation of these interactions can improve the team dynamics and reduce team tensions. It is suggested that routine use of these techniques in project or team environments could improve performance and increase the probability of successful project outcomes
