The complex challenges evaluators respond to today require learning from other disciplinary approaches and practices and including multiple voices during the evaluation process. We are presenting a novel collaborative virtual tool for exploring and designing project evaluations (EViD Tool) which is the outcome of a 3-year interdisciplinary research collaboration in Design and Evaluation between Lancaster University, UK and Curtin University, AU. EViD Tool encourages bringing together project teams, partners and stakeholders and guides them through exploring the evaluation needs and potential of their projects. The tool, which is freely available to non-profit organisations and for educational purposes, is now a Lancaster University spin-out company.
