Large airport operational readiness (LAOR) is a critical factor that directly impacts the opening of airports to the public. However, limited research exists on the risks affecting LAOR schedules. This article explores the risk breakdown structure and risk interactions model of LAOR schedule risk. An empirical investigation was conducted on four large hub airports from 2009 to 2021 using grounded theory procedures. The study identified 21 risk factors categorized into management (highest frequency), technical, process, participant, and environmental risks (lowest frequency), which implied that risks primarily existed within a project rather than in the external environment. A systematic model incorporating risks and their interactions revealed that the primary risk transfer path was from the subject subsystem (participant risk) to the object subsystem (technical and process risk). The findings expand the knowledge domain of infrastructure risk and provide pragmatic risk evaluation and response guidelines.

The transition from projects to operations requires a spanning from more temporary, goal-oriented, and evolving organizational forms to more permanent, routine, and ongoing organizational forms. A question of practical and theoretical significance is how to organize the transition to operations in large inter-organizational projects. To answer this question, we conducted a longitudinal case study of Beijing Daxing International Airport, which is the largest transportation hub in China to date, and provides rich evidence for successfully managing the transition to operations. By analyzing the organizational design strategy, structures, processes, and management of people in the transition, we provide a synthetic framework for designing the transition to operations in large inter-organizational projects. The framework provides a set of considerations to design organizational boundaries that build connections, emphasize coordination, and achieve continuity between projects and operations. This study contributes to the nexus of operations management and project management and the organizational design of large inter-organizational projects.

Given that a strong owner has been identified as an important factor in the success of megaprojects, there has been a growing recognition of the importance of megaproject owner organizational capabilities. However, the questions of what organizational capabilities do owners need to foster successful megaprojects, and whether these capabilities are the stronger the better, have yet to be addressed. To answer these questions, this study identified the dimensions of owner organizational capabilities based on literature and interviews, and developed several sets of parallel hypotheses. Based on the 229 valid questionnaire data collected, the relationships between owner organizational capabilities and megaproject success were analyzed through hierarchical multiple regression, and the results were discussed through expert interviews. The findings show that owner coordination, dynamic, and system integration capabilities have positive impacts on megaproject success, with coordination capabilities being the most significant. While the impact of motivational capabilities on megaproject success is inverted U-shaped. This study provides an actionable dimensional framework for megaproject owner capabilities, moving the field of owner organizational capabilities beyond the conceptual level. This study provides empirical evidence for the importance of megaproject owner organizational capabilities and takes a more dialectical view of a strong owner. The empirical results can provide insights and guidance on the configuration and development of megaproject owner capabilities.

External program manager involvement can provide professional and systematic management services to owners. It can help to manage and coordinate different subprojects and ensure the achievement of the overall strategic goals of large projects. The promotion of external program manager involvement is not only efficiency-driven, but the institutional environment also has a significant impact. This study developed a theoretical model to explain how external program manager involvement is influenced by external institutional forces (coercive, mimetic, and normative pressures) and internal top management support. Based on a questionnaire survey, this study tested the research model through partial least-squares structural equation modeling. The empirical results revealed that coercive pressures have no significant impact on external program manager involvement; owners' top management support acts as a complete mediator between the mimetic pressures and external program manager involvement; normative pressures have the greatest impact on top management support and external program manager involvement, and top management support plays a key but partially mediating role. A direct contribution of this study is to reveal how different types of isomorphic pressures can be better exercised to facilitate the involvement of external program managers. Going further, by incorporating both external institutional pressures and internal top management support into the research model, this study provides insight into how organizations are influenced by external institutions to apply tools or approaches internally.

In emerging economies, infrastructure projects are in full swing. There is a wealth of replicable experience for exploitation. Simultaneously, more technologies and methodologies require further exploration. This makes fostering ambidextrous innovation strategies (i.e., the tradeoff between exploitative and exploratory innovation strategies) a common and vital practical issue. Large infrastructure projects are unique one-off endeavors but have somewhat repetitive and persistent characteristics. It is a particular “intermediate” form between temporary projects and permanent organizations. Previous research on fostering ambidextrous innovation strategies cannot simply be replicated in large infrastructure projects. To address this issue, this article investigates the relationship between team heterogeneity and ambidextrous innovation strategies and also the role of team learning and identification in large infrastructure projects. Data were collected from 269 responses from 31 large infrastructure project delivery teams in China. The findings show that team heterogeneity has a positive linear effect on exploratory and ambidextrous innovation strategies and an inverted U-shaped effect on exploitative innovation strategies; team heterogeneity can better foster ambidextrous innovation strategies through improving team learning; the moderating role of team identification in the overall mechanism differs from the usual assumptions in permanent organizations. Overall, this article extends the existing ambidexterity research in the “intermediate” form between temporary projects and permanent organizations. It provides insights and guidance on fostering ambidextrous innovation strategies in large infrastructure projects.@en

In infrastructure project practice, balancing and maximizing the combined effect of exploratory and exploitative innovation have attracted increasing attention, but it is still unclear how to foster ambidextrous innovation in infrastructure projects. To address this gap, we draw on the differentiation-integration framework of ambidexterity theory to deconstruct tactics for fostering ambidextrous innovation in infrastructure projects. A total of 313 observations were collected from infrastructure under construction, and the path hypotheses were tested by hierarchical regression. The findings suggest that in infrastructure projects, task conflict and expertise integration of diverse cross-functional teams provide powerful and complementary tactics for fostering ambidextrous innovation. The moderating effect of team autonomy support on the impact of team diversity on differentiation and integration tactics presents three different results. This study not only enriches the literature on how to foster ambidextrous innovation in infrastructure projects but also expands the ambidexterity research at the cross-functional team level and in infrastructure project contexts.
