We are pleased to publish our fourth and last issue of Volume 30. This issue features five articles contributing innovative approaches to project management. We would like to thank our peer reviewers for their invested time and expertise as well as managing editors Jennifer Cross and Brian Smith and associate editors Bastian, Gandhi, Mallak, Murray, and Scala for their contributions to this issue. Recently awarded at the American Society for Engineering Management (ASEM) annual conference and named after EMJ’s founder editor Ted Eschenbach, we would like to acknowledge that the 2018 ASEM Eschenbach Award for the Best EMJ Paper Award was given to Molly Floyd, Kash Barker, Claudio Rocco, and Mackenzie Whitman for their 2017 EMJ article “A Multi-Criteria Decision Analysis Technique for Stochastic Task Criticality in Project Management.” Our issue begins with an article entitled “Predicting Military Construction Project Time Outcomes Using Data Analytics” by Innocent, Wasek, and Franz. Their article provides a model to predict military construction project time outcome in the early phases of a project. Furthermore, this article presents an analysis of the factors that affect project time in the construction industry that engineering managers can use to understand other factors as they relate to their own domain/industry. The second article in this issue is “Effects of ProjectRelated and Organizational-Related Factors on Five Dimensions of Project Performance: A Study Across the Construction Sectors in Malaysia” by Sekar, Viswanathan, and Sambasivan. This article contributes to the engineering management body of knowledge in three ways: (1) combining project-related and organizational-related factors in a single framework, (2) analyzing the impact of factors on five dimensions of project performance, and (3) analyzing the framework across different sectors of construction industry. Engineering managers can use their work to identify the project-related and organizational-related factors that have significant relationships with each dimension of project performance at different sectors in the construction industry and devise strategies to complete their projects as planned without compromising on the quality. “Collaboration in Integrated Project Delivery: The Effects of Trust and Formal Contracts,” the third article authored by Zhang, Huang, and Peng, shows project collaboration is affected by the two basic governance mechanisms, formal contracts and trust including goodwill trust and competence trust. An engineering manager can use their work to increase their collaboration levels and maximize the project performance in Integrated Project Delivery projects by knowing the most suitable partners will have a high level of goodwill trust and moderate level of competence trust. In addition, managers can realize a well-specified contract is necessary to maximize collaboration and to seek an optimal mix of competence trust and formal contracts to facilitate collaborations. The fourth article in this issue, “Project Governance, Project Performance and the Mediating Role of Project Quality and Project Management Risk: An Agency Theory Perspective,” was co-authored by Haq, Liang, Gu, Du, and Shuping. This article measures the influence of project governance on project performance directly and through the mediation of project management risk and project quality in IT and software development projects of Pakistan. This article provides engineering managers with insights on how effective project governance directly influences project performance and helps managers understand the role of leadership to enhance project performance. Our fifth and final article in this issue is “Uncertainty Analysis and Resource Allocation in Construction Project Management” co-authored by Zhong, Chen, Zhou, and Hu. From a holistic perspective, this article assists engineering managers by providing a deeper understanding of the relationship between uncertainty, project parameters, and project performance. The premise of dealing with uncertainty in this article is to determine the impact of uncertainties on project performance. This article presents a framework for quantitative analysis that combines a fuzzy mathematics approach with system dynamics theory. Simulations generated using a model based on the framework show that uncertainties affect project performance by changing project parameters and that the mechanisms involved depend on the sources of the uncertainties. Furthermore, while technical and financial uncertainties mainly influence project costs, uncertainties related to markets, regulations, and organizational structures affect both project duration and cost. Finally, strategies for coping with uncertainties in a resource allocation perspective are presented. The Engineering Management Journal publishes rigorous and relevant research and applications that add value not only to the academic community but also to the engineering management practitioner community. We invite research and applied engineering management articles from both academics and practitioners and welcome all types of research methodologies that address the engineering management domain areas.
