Megaprojects Intersections of complementary points of view

Megaprojects are generally defined as large-scale investment initiatives worthing 1b€/$ or more, facing similar problems independently from the country where they are implemented and the industry they belong to. Even if different researches and approaches have been developed in the last 20 years about this topic, there is still a lot of debate on it, and a holistic approach for effectively manage those initiatives is still missing. What is clear to all researchers and expert in this field is that a tradional-linear management approach is simply not enough, as, at many stages of a megaprojects, iterative and feedback effect occurs due to stakeholders’ involvement increase and continuous interaction between them. The Megaproject Research Interdisciplinary Team (MeRIT) – established in 2018 with the intention of combining the multiple aspects related to the design and implementation of megaprojects – aims to promote the debate around Megaprojects among all categories of stakeholders involved in a megaproject’ supply chain, in order to increase the awareness of complex phenomena in charge of criticalities and common problems they face all over the world, and looking for improvement of performances on the whole life cycle (including the selection, design, construction, operation and de- commissioning). This volume is one of the multiple outputs of the research group and presents a range of perspectives on megaprojects. This multidisciplinary approach is welcome and promising, since megaprojects themselves are multifaceted and intertwined. They are at the same time physical-technicalengineering constructions, financial-economic undertakings, and sociopolitical negotiations and outcomes. Success typically requires mastery in each of these domains, and failure can come from anyone.
