Public transport interchanges often involve several stakeholders for planning and decision-making. As a result complexity leads to inefficient processes, leading to indecision, disruption, or costly delays. Consequently, the paper focuses on the application of tools for navigation and prioritization of opportunities in the need finding, fuzzy-front end, or mystery phase as introduced by Martin (2009). The paper outlines in a case study how a multi-stakeholder platform can progress from complete ambiguity in project definition through to clearly defined and understood projects that have a shared intent across the multi-stakeholder platform. These tools have been applied in a public transport context, by demonstrating the process of integrating digital innovation into various stakeholders through a participatory research process. The paper introduces the research background; discusses the hypothesis; outlines the case study; emphasizes its significance for multi-stakeholder decision-making and discusses the opportunities for the built environment.
