Although the use of project teams is on the rise, there is a limited understanding of how project managers can ensure project team success. Research to date is relatively broad and does not pinpoint how and why leadership influences success in a project team context. Along these lines, we draw from social learning theory to illustrate that ethical leadership influences project success through leader trust and knowledge sharing.

We collected data from 175 project team members from the information technology and software industry to evaluate our hypotheses. The results were analyzed using structural equation modeling.

Our findings support our hypotheses, illustrating that ethical leadership is related to leader trust and knowledge sharing, and that leader trust and knowledge sharing mediate the relationship between ethical leadership and project success.

Our work illustrates that the behaviors inherent in ethical leadership may be particularly well-suited for these project team challenges. Ethical leaders help team members understand that project success is possible when team members are transparent with one another, discussing their goals and challenges, and then working together to ensure their actions are coordinated in a way that increases the success of the overall project.

For those in industries or organizations where project teams are commonly used, our study may help to attract, select, and retain project managers that exhibit ethical leadership tendencies. Project managers are likely to be attracted to settings that align with their leadership style. Thus, organizations could focus on developing a culture that focuses on process over results.

We sought to align with the contingency approach to leadership, which suggests that the ideal leadership style depends on the followers, and the context in which the leader and followers interact. Specifically, we investigate ethical leadership as an ideal approach for project managers influencing members of their project teams. Our study demonstrates how ethical leadership is an ideal, context-specific approach that project managers can apply to increase the chances of project success.

This paper sets out o determine influences on team performance processes and develop an overall team success model (TSM).

A total of 55 individual students grouped in 18 teams, ranging in size from two to five, were measured at several stages in semester‐long team projects. Forty‐four separate questions were studied in each measurement stage. These 44 questions were reduced to five factors through exploratory factor analysis (EFA). Structural equation modeling (SEM) was then used to determine the significance and interrelationships of these factors, as well as the influence of gender and grade point average (GPA).

This research develops and validates a series of factors that lead to IT team success. The factors include emotions, personal processes, and team processes. The overall R² of the final model was high at 0.601. Significant relationships were found between many factors. GPA had a positive impact on team processes, while negative emotions showed a negative correlation with team processes. Team processes and trust had positive impacts on project success/grade. All were significant at p<0.05. Passive positive emotions reflected a negative effect on project grade but only at p<0.10.

The major limitations of the project are the relatively small sample size as well as the use of student team projects. The work can serve as a framework for larger and more varied projects.

Virtually all significant information technology (IT) projects are developed by a group of individuals working together as a team. The development of a team success model which can improve project success can have tremendous value to industry. Implications may be extendable to other team projects.

Past analysis of the factors that lead to information systems project success has been neither comprehensive nor conclusive. Further study is recommended with more significant and varied projects to further validate the strong preliminary research findings.

The traditional Chinese culture has always emphasized the authority of leaders and their “top-down” influence over subordinates tangled with “bottom-up” management. Paternalistic leadership can both nurture and restrict growth in mega-construction projects, due to the unique consequences (i.e. positive vs negative implications) for project teams. Hence, the present study aimed to explore the impact of paternalistic leadership (PL), team members’ voice (TMV) and team resilience (TR) on the mega-construction project success (MPS) in China's Belt and Road Initiative (BRI).

A surveyed-based sample of project professionals (N = 563) directly linked with the BRI was employed for statistical estimations with partial least squares (PLS) structural equation modeling (SEM).

Paternalistic leadership styles, including authoritarian leadership (AL), moral leadership (ML) and benevolent leadership (BL), significantly influence the mega-construction project success in BRI. The findings empirically validated that both BL and ML increase the likelihood of mega-construction project success. However, AL could impose a threat through its underlying negative influence. In addition, leaders with benevolence and morality have a positive influence on TMV and TR, while leaders with authoritarianism signal a negative impact. Furthermore, both TMV and TR significantly and positively mediate the relationships between AL-MPS (Model-1), BL-MPS (Model-2) and ML-MPS (Model-3), respectively.

The present study is a groundbreaking endeavor that fills a crucial research gap by investigating mega-construction project success in the BRI through paternalistic leadership, project team members' voice and team resilience in a multi-mediation model. These novel findings offer valuable strategic insights for managing mega-construction projects in countries with paternalistic solid cultural foundations, enabling project managers to navigate cultural nuances and optimize megaproject outcomes.

This paper aims to examine the impact of humble leadership on project success. The authors propose that such an effect is mediated by team-building, and top management support moderates the direct relationship (humble leadership and project success) as well as an indirect relationship through team-building.

Data were collected from 337 individuals employed in the information technology sector of Pakistan. A two-step approach consisting confirmatory factor analysis and structural equation modeling was used for analysis. To examine conditional direct and indirect effects, the authors utilized model 8 in PROCESS.

The results showed that humble leadership is positively related to project success. Furthermore, team-building partially mediates the relationship between humble leadership and project success. Moreover, top management support was anticipated to have a moderating effect on the direct and indirect link (via team-building) between humble leadership and project success.

Drawing on the conservation of resources theory, this study found that how humble leadership is vital for project success, and thus, extends the utility of the concept of humble leadership to the project literature.

In the construction industry, site managers are responsible for the day-to-day on-site running of a project. Site managers are required not only to ensure that work is done safely, on time, within budget and to the right quality standards, but also to manage any delays or problems encountered on-site during a construction project. Thus, a site manager has a significant position in the success of a construction project. However, there is a lack of studies considering the role of the leadership style of a site manager in construction project success. In this study, not only the effect of the transformational leadership (TL) style of site managers on the success of construction projects is assessed, but also the mediating role of team-building (TB) and team innovation between TL and project success is studied.

The proposed hypotheses are tested by comparing the performance criteria of construction projects with the TL style of site managers. The success criteria of the projects are examined using project documents and client opinions, and the TL of site managers, TB aspects and team innovation in projects are assessed by asking from their subordinates. The Pearson correlation coefficient is employed to investigate the relation between every two variables.

The results illustrate that the TL of a site manager is directly related to project success; thus, the findings would confirm the importance of selecting appropriate site managers for construction projects. Moreover, while there is a mediating role of TB between TL and construction project success, team innovation does not have a mediating impact in design-bid-build (DBB) construction projects.

As there is a lack of studies assessing the TL effects on the success of construction projects and the significant role of site managers, this study is one of the first researches that tested these impacts and evaluated the mediating role of TB and team innovation between TL and project performance.

The purpose of this paper is to explore critical success factors (CSFs) in interdisciplinary building design projects from the view point of the project members themselves. While there is a plethora of research on CSFs, there is a paucity of studies that examine CSFs within this unique project context.

Semi‐structured interviews, a survey and facilitated workshops were used to identify factors and their interrelationships within the project context.

Thirty‐one primary CSFs were distilled which were then further grouped into four interdependent group factors: management factors, design team factors, competencies and resources factors and project enablers. It would appear that there are factors that are particularly important in such project environments, which do not figure strongly in other project environments. These factors are related to the socio‐political dynamics of inter‐disciplinary team work such as passion and enthusiasm, shared values, creativity and innovation and represent so‐called “super soft factors” which reflect personal success and its importance in achieving positive project outcomes.

Although there has been significant research on CSFs in construction projects, little attention has been paid to those which are related to the collaborative design phase of such projects.

The results suggest that it is worthwhile for managers in construction related organisations and beyond to recognise the interdependencies which exist between the project context, processes and the project members' experience and affinity to the project and the team itself in project work to achieve desired outcomes.

This paper extends the CSF literature by identifying the nature of the primary factors and their interrelationships which influence project outcomes in collaborative design projects.

The adoption of enterprise resource planning (ERP) systems is a major challenge to organizations. Many implementation teams struggle to ensure the success of such projects. The information systems literature indicates that the team attributes of breadth of experience, empowerment, and cohesion are necessary conditions for project success. This paper aims to investigate how the nature of implementation teams may affect adoption success.

The research employs a positivist, qualitative field study approach to investigate the role of the implementation team attributes in ERP system adoption. Project success is assessed on three determinants, i.e. support of organizational activities, stakeholder satisfaction, and system acceptance.

The findings provide new insights as to the extent to which prior assumptions from the information systems literature apply in the ERP system implementation context. The results indicate that team empowerment and cohesion are not necessary precursors to project success as their impact depends on the adoption context.

The circumstances under which the impact of low team empowerment and low cohesion can be alleviated in ERP adoption projects are discussed.

The paper offers explanations as to why certain established assumptions regarding information systems teams and project success may not apply to an ERP adoption context.

This study investigates the impact of network positions on inter-team conflicts and project success in megaprojects.

Network position is measured with centrality and structural holes. Substantive conflict and affective conflict reflect inter-team conflicts. A questionnaire survey was implemented in Chinese megaprojects, and 309 valid questionnaires were collected. The data were analyzed using structural equation modeling and bootstrapping methods.

The results show that centrality negatively impacts project success, while the presence of a team in a structural hole has no significant impact on project success. Centrality is negatively related to substantive conflict and is positively related to affective conflict. The team in a structural hole has a positive effect on substantive conflict and a negative effect on affective conflict. Substantive conflict and affective conflict have positive and negative effects on project success, respectively. The effect of network position on project success is mediated by inter-team conflict.

This research provides a reference for megaproject managers to better conduct network governance, manage inter-team conflict, and successfully manage projects. The study did not investigate the effects of changes in teams' network positions on project success. Future research should explore this facet of megaprojects.

This research adds to existing research on network position, and reveals that project network governance is important for megaproject success. This provides a new direction for megaproject management. Furthermore, the results validate constructive and non-constructive roles and the mediating role of inter-team conflict. This complements the literature on conflict management, providing a reference for megaproject managers when managing inter-team conflict.

The purpose of this paper is to emphasise the importance of high levels of trust and collaboration for increasing the likelihood of project management (PM) success. However, the link between these three constructs remains unclear.

In this study, the authors use structural equation modelling (SEM) based on the findings from an international survey of 151 project practitioners to demonstrate the significance of project team trust and collaboration for increasing the likelihood of PM success.

The results indicate that PM success becomes more likely as the degree of collaboration improves which, in turn, is influenced by an increase in the level of trust between team members. The two factors of PM success are project performance and knowledge integration and innovation. The six factors of the degree of collaboration that were studied are physical proximity, commitment, conflict, coordination, relationships and incentives. The three factors of the level of trust investigated are expectations, knowledge exchange and imported trust.

The results of the study are expected to provide insight for project practitioners to increase the likelihood of PM success by taking cognisance of the factors that influence collaboration and trust. The results of the study may also provide insight into teaching and learning in tertiary education, in terms of professionalism and integrity issues.

This paper presents a new perspective for investigating PM success. SEM techniques are used to determine the likelihood of PM success by promoting trust and collaboration in the project team. This unique approach highlights the “human factors” that influence perceived PM success which should benefit both researchers and practitioners.

Failures in both followership and leadership become inevitable as mega construction projects are directed and controlled by toxic leaders. Consequently, team member's desire for knowledge hoarding silence is triggered and goal alignment between the leader and team members suddenly fades away to realize success in mega projects. Considering the growing importance of these rarely examined constructs and fragmented literature on toxic leadership (TL), team silence and mega project success (PS) in the global construction industry, the present study aimed to examine the effects of TL and project team member's silence (PTMS) on the success of mega construction projects. Moreover, the mediating influence of PTMS to link TL and mega construction PS has also been explored.

Drawing on survey data of 326 project professionals directly associated with mega construction projects worth US$62bn under the China–Pakistan Economic Corridor (CPEC), the conceptual model was tested with covariance-based structural equation modeling (CB-SEM) using Mplus program. Scales were adapted from previous research to measure TL (with its five-dimensions including abusive supervision, authoritarian leadership, self-promotion, narcissism and unpredictability), PS (with its three-dimensions including project management success, project ownership success and project investment success) and project team members' silence. Reflective–formative second order assessments were specifically applied to measure the multi-dimensional nature of TL and PS, respectively.

Mplus estimations revealed that TL negatively influences PS, besides forcing a culture of silence among project team members. Interestingly, the relationship between TL and PS is also negatively mediated by the PTMS.

The present study's findings are derived from data of project professionals (N = 326) to examine success in megaprojects under the CPEC. Hence, these findings may be re-validated through future studies on similar megaprojects (e.g. China's Belt and Road Initiative (BRI) worth US$8tn) that may also be predicated by TL tendencies, silent cultures and high-stakes involved to seize PS.

Policymakers, construction practitioners and other key stakeholders (e.g. departmental heads/supervisors) can take advantage of this new evidence to better interpret the success paradox in mega projects, and to reduce the spread and long-term damage of TL on team members and eventually create opportunities for PS.

The present study's novelty is manifested within this first empirical evidence on TL that breeds team silence in underperforming mega projects. Notably, present study offers alarming evidence on mega projects that can be easily derailed from success, as they continue to suffer from team silence and TL.
