The purpose of this paper is to enhance the understanding of what project complexity is, what drivers and factors that influence complexity and how consequences for organizational performance can be assessed.

The research is explanatory and based on literature review, model development, interviews and case studies. The model is validated through a case study.

The findings are a model for identifying and analyzing complexity drivers and complexity factors. The model starts with generic complexity drivers such as ambiguity, uncertainty, unpredictability and pace. These drivers are in each project influenced by nature and by socio-political, economic and technological surroundings to result in complexity factors that are specific to the project analyzed. The model can be used to analyze project complexity and to define requirements for the organization of the project and guidelines for the execution.

The research is limited to large projects with a technical delivery of some kind of facilities.

The model can be used to assess the required capability of the organization for successful project execution.

The contribution of the research is a new model for understanding project complexity. The distinction between project complexity drivers and factors is essential as well as the taxonomy for the factors building on and adding to already published research.

The purpose of this paper is to show that project success is dependent on the project management approach selected, relative to the challenges posed by the project, and to develop an analytical model for analyzing the performance of the project organization.

The research is based on literature review, model development, interviews, and case studies.

The findings define two different approaches in project management: The prescriptive approach focusses on the formal qualities of the project organization, including governing documentation and procedures. The adaptive approach focusses on the process of developing and improving a project organization, project culture and team commitment. The two approaches have been identified through studies of three different case projects. An analytical model, referred to as the Pentagon model, has been applied for analyzing the performance of the project organization and explaining the project management approach. The model focusses on five different organizational aspects: structure, technologies, culture, social relations and networks, and interaction.

The research is limited to megaprojects and to project management success.

It is suggested that project teams consider and select their project management approach at project initiation, and accordingly decide on relevant success factors to focus on. The adapted Pentagon model can be applied to develop the project management organization and assess its performance in the course of project delivery.

The contribution of the research is the application of the analytical model, and the identification as well as illustration of the prescriptive, vs adaptive management approach.

Hard project management practices, based on strict planning and control, are traditionally applied in construction projects, although research frequently promotes the importance of teams for various project outcomes. Thus, the purpose of this paper is to examine the importance of hard project management and team motivation for process performance in construction projects. A hypothesis tested is that hard project management can impair process performance if team motivation is not promoted.

The paper presents and empirically tests a structural equation model, with and without a mediating link between hard project management and process performance, based on data from a survey of 2,175 respondents, representing contractors and clients involved in 109 Swedish construction projects.

The results confirm that hard project management is best conveyed through teams to enhance process performance. “Path analysis,” using the model with the mediating link, confirms that neglecting team motivation can significantly impair process performance.

The data set provides unusually high representation of views of contractors and clients involved in diverse Swedish construction projects. Thus, the results have likely relevance in other project-based industries and/or national settings, but this possibility requires further investigation.

The findings show that team motivation is a key process performance factor; hard project management may indeed be important, but its effects will be enhanced by (and partially mediated through) team motivation. Thus, the findings have important theoretical and practical implications for the development of project management practices.

This study examines scholarly communications in the International Journal of Managing Projects in Business (IJMPB) and identifies the journal's leading trends from 2008 to 2019.

This study analyzed a sample of 522 articles published in the IJMPB since its inception in 2008 until 2019. A set of bibliometric measures was used in the study to identify publication trends, citation structures, leading authors, institutions and countries. Additionally, analysis of research methodologies, industrial sectors and research themes of the articles was carried out through a rigorous content analysis. To examine the changes in journal expansion over time, the duration of publications (from 2008 to 2019) was divided into three subperiods.

The study findings show that 793 authors from 370 institutions and 58 countries contributed to the journal during this period. In terms of contributions, Australia and the Scandinavian countries are at the top, while Asian and African countries occupy a lower position. Moreover, among authors, Derek H.T. Walker was found to be the most prolific, with the highest weighting score and number of articles. Similarly, RMIT University of Australia emerged as the most productive institution. The articles were predominantly case studies followed by mixed methods (i.e. both surveys and interviews are used for data collection). Most of the articles in the sample were related to project management in general. However, several articles reported on construction, information technology (IT) and manufacturing projects.

This study is useful for the researcher community to understand the journal's scientific productivity. Further, it will also help identify dominant topics in the field of project management.

This is the first comprehensive review article presenting a general overview of the journal's leading trends and researchers since its inception in 2008.

The purpose of this paper is to understand the underlying logics applied by different project evaluation approaches and to propose an alternative research agenda.

This paper explores the project evaluation literature via conducting a qualitative research applying systematic literature review and thematic analysis.

The project evaluation literature has mainly concentrated on the objective aspects of project evaluation and overlooked the subjective aspects that reflect the temporal, dynamic, complex and subjective nature of today’s projects. The authors propose a meta-framework that helps project practitioners to select an appropriate project evaluation criterion for their projects by considering the strengths and limitations of their preferred project evaluation model as well as making project evaluators aware of the underlying logics associated to diverse project evaluation approaches.

This study suggests that new conceptual approaches to deal with some of the major challenges in the project evaluation field. Practice-based views, narrative analysis and actor-network theory are likely to be useful tools to better understand and cope with the projects’ uncertainty and complexity.

The findings of this research assist project management practitioners and particularly project evaluators to enhance their understanding of the subjectivity, complexity and dynamics of current projects. To increase the reflexivity and resilience of project evaluation practice, this study also proposes new directions to apply different criteria, sub-criteria and indicators to the evaluation practice.

The originality of this study relies on transcending the conventional objective and rational approaches prevailing in current project evaluation practices. It proposes a research agenda that pave the way to address the shortcomings of conventional project evaluation practice.

The purpose of this paper is to answer the research question: “does the incorporation of sustainability as a new school of thought in project management support project success?” The authors carried out a systematic literature review (SLR) on relevant empirical studies before 2018 to answer this question.

The authors carried out an SLR by selecting, extracting, analysing and critically appraising relevant literature that met pre-specified criteria by using transparent, well-organised and replicable steps. The main sources are publications in peer-reviewed journals regardless of their impact factor because the topic of incorporating sustainability in project management practices is restrained by a lack of research.

Based on the analysis, it seems that incorporating sustainability into project management may support project success. However, more evidence is required to support this finding as there are too few relevant empirical studies in the literature.

Therefore, considering sustainability as a new school of thought in project management is premature, and there are recommendations for further research at the end of this study. There are several limitations to the studies chosen, which may have significantly affected results, and thus may affect outcomes in this study.

Project success needs to be the main endeavour when incorporating sustainability into project management, and it should be a key criterion when considering sustainability as a new school of thought in managing projects. The most challenging elements of project success that need to be addressed are cost and time. This study contributes to a better understanding of the impact of PSM on project success. It facilitates decision making in considering sustainability as a new school of thought in project management. Furthermore, it defines a need for more research work in this potential paradigm shift in managing projects.

The purpose of this paper is to address the primary research question, which is what is the relationship between the project manager’s (PM) possession of the Project Management Professional (PMP) certification and the level of the safety culture present in the construction project the PM manages.

The research was based on a survey of a purposive sample, 109 engineers and first-line supervisors worked in 23 construction projects of which ten were led by PMP-certified PMs and 13 were led by PMs lacking PMP certification. Each PM completed a demographic questionnaire for the predictor variables of PMP certification controlled for age and experience. To assess the criterion variable of safety culture total score, engineers and first-line supervisors working in the same project completed the questionnaire of safety culture values and practices.

Results of this study indicated the level of safety culture was significantly different, and improved, for engineers and first-line supervisors who work under PMs with PMP certification compared to the level of safety culture in projects managed by PMs with no PMP certification. Although alignment of safety culture perceptions among different levels in the organization helps to achieve a positive safety culture, the role of the PM in transferring, implementing and maintaining the safety culture in the construction project is fundamental, particularly in small-to-medium sized enterprises (SMEs).

This study addressed the role of the PMs managerial skills in the safety performance of Saudi Arabian SMEs. The principal finding was that PMs with managerial skills perform better regarding safety performance in SME construction projects than PMs lacking managerial skills. The primary recommendation is that leaders in construction projects must carefully evaluate engineers’ managerial skills before hiring the individuals as PMs. A PM’s promotion model developed in this study provides a suitable framework and business process component for construction leaders seeking to maintain safety performance successfully.
