ItemWhy may public infrastructure projects over-promise likely outcomes?(Australian Institute of Project Management, 2016-11-01)The prevailing approach to measure project success compares an ex-post outcome with the ex-ante plan. Comparisons of project success are often questioned, and actual success is unlikely to realised if the initial plan is excessively optimistic such as exaggerated benefits, overlooked risks, and unrealistic assumptions. Published literature suggests that technical inadequacies of estimation models, psychology of human mind, economic obligation for risk, and organisational misrepresentation may be factors that can explain this planning fallacy in projects. Nevertheless, these explanations are considered lacking as they do not adequately address the complexity of infrastructure project decision process. This paper goes beyond planning fallacy in a quest for a better explanation. A workshop of project experts was convened to test the earlier understandings relating to behaviours exhibited during the initiation of an infrastructure. Importantly it framed much of the interactive dialogues among participants around seven case study projects that were considered in the 2012 Parliamentary inquiry of the committee of the Public Accounts and Estimates Committee (PAEC) that explored the effectiveness of decision making in Victorian infrastructure delivery. It emerged that one of the key behaviours was considered to be the use of power in decision-making during project initiation. Power manifests as the ability to influence others’ intent. In projects, its root lies in information, expertise, authority, legitimacy, and reputation. The notion of power has been recognised as a fundamental concept to explicate the behaviour of actors in a collaborative environment. This paper focuses on the delivery process of public infrastructure projects and investigates the asymmetry of power among participants in an attempt to unravel the complexity of decision authorities and delegations. In a conceptual isolation of central agencies from delivery agencies, a new concept of informal authority is devised to provide a reliable explanation of how delivery agency’s optimism may pay off in the presence of an asymmetric distribution of power. The paper concludes that power asymmetry is a critical success factor in public infrastructure projects and makes suggestions for future improvements.he prevailing approach to measure project success compares an ex-post outcome with the ex-ante plan.
