Shaping complex mega-projects: practical steps for success

Abstract

Mega-project success is difficult and often interpreted differently by different stakeholders. Too many large engineering/science projects fail in terms of budget, schedule and/or performance. Such failures have profound implications for the construction and commissioning organisations, the funders (often spending public money), and end users. Successful design and delivery is, therefore, not only a commercial necessity but also a societal imperative. In this paper, I focus on the inception, planning and feasibility phases of complex mega-projects, based on extant and updated research into the literature and case studies. I examine key success drivers from recent studies of large-scale high-technology projects, drawing out early stage factors shown to be especially potent. I discuss the importance of project goal(s) and success definitions; tackling complexity; and early selection of competent procurement processes. I explore resilience-building processes to curb optimism, learning from like projects, and a ‘mission-assurance’ mindset. Lastly, I advocate an approach to threat management beyond the traditional risk assessment models. This paper draws out the more subtle, often overlooked, aspects of complex mega-project management shown to be crucial at the start-up stages. The findings led to the development of a complex project audit tool now offered to readers.
