6. Discussion
In this section, we discuss the implications of the trialed diagnostic process, as well as the produced results/contents, for sustainable infrastructure delivery. We then conclude by discussing broader implications of this research for policy and planning research in the context of sustainable development.
6.1. Implications of the trialed process
Although we cannot determine the ultimate effectiveness of our proposed intervention approach for sustainable infrastructure delivery based on a single trial and in the shot-term, we can provide critical reflections on the trialed application to indicate its potential for supporting sustainable development.
Using the case of water services planning for an urban renewal area in Australia, the trialed process brought various stakeholder groups into a participatory and interactive conversation through which they systematically revealed a range of impediments to sustainable infrastructure delivery and explored potential coping strategies. The participants stated that although some of those impediments were not entirely unknown, they were hardly ever made explicit and systematically discussed in a participatory environment involving various stakeholders. In contrast, the diagnostic process provided a platform for representatives across different organizations and specializations to engage in clear-cut discussions around their confronted problems, which often have trans-organizational causes and impacts. This outcome is particularly important for addressing the implementation deficit of sustainable development, since shared understanding and concerted efforts of all parties are required to tackle impediments, drive change strategies and avoid detrimental failures (Voß et al., 2007).
The trialed process also enabled reflexivity as part of the planning process. After the trial, those participants who were advocates for sustainable infrastructure in their organizations expressed that they realized they were often emphasizing benefits in their advocacy, but were less proactive in addressing the complexities and vulnerabilities of transition agendas. They mentioned that the deliberate attempt to reveal vulnerabilities and risks associated with sustainable infrastructure planning helped them to better anticipate and engage with the concerns of those who are ultimately responsible for signing off on multi-billion dollar investments, and highlighted the necessary competencies for addressing those concerns.
