His research brings a management science/social science perspective to the subject of sustainability in project management, focusing on aspects of the topic in the context of projects and temporary multi-organizations.

Earned Value Analysis (EVA) is a method that has gained traction in some business sectors to report project progress and help control performance. Yet the literature reports mixed results as to its effectiveness in helping deliver successful projects and, additionally, much of the previous studies on the topic is conceptual in nature focusing on the design of the EVA system. We therefore extend knowledge on EVA by analysing the impact of EVA on the levels of success of two projects that utilised the method. This is done through the prism of agency and organisational justice theories. A framework is proposed of EVA conditions of success, incorporating both design and operational aspects of the EVA system. The framework is used to develop testable propositions that can guide further research into the effects of EVA-based systems on the creation of agency-related characteristics in the project environment that are conducive to project success.

<p>Inter-organizational networks are frequently used to execute large and megaprojects. This study develops a theoretical framework for the governance of these networks. Twenty-eight case studies, each representing a network for a project, were assessed using 124 interviews in ten countries. A three-layer governance model is derived from the analysis. At the lowest layer (network governance) is the individual network of organizations collaborating in a project. This layer is explained through Multi-level Governance Theory. The intermediate layer (governance of networks) addresses the steering of the different networks these organizations are part of, such as for training, certification, safety etc.. At the top layer (metagovernance) are the ground-rules, set by governments or other investors to regulate how the two other layers are allowed to set up their governance. The study’s resulting theory combines three so far separate levels of governance into an overall understanding of large inter-organizational networks for projects. It provides parameters for practitioners to optimize their networks for better project results.</p>

The impact of behavioral aspects on project success remains an area that requires more attention. Drawing on the social exchange theory (SET), our study tested the mediating role of project citizenship behavior (PCB) in the relationships of all four organizational justice dimensions (i.e., procedural, distributive, informational, and interpersonal justice) with project success. A time-lagged survey of project team members ( n = 233) was conducted and analyzed through structural equation modeling (SEM). The results indicate that all four organizational justice dimensions are positively associated with project success, whereas informational justice appears to be the most influential dimension, and that PCB mediates all of these relationships. Project managers/sponsors should enact organizational justice and enhance project citizenship to achieve project success.
