Systematic Literature Review of Project Manager’s Leadership Competencies

Purpose: Over the last few decades, a large number of research studies have been carried out on project manager’s leadership competencies. However, systematic literature reviews are still scarce in the project management literature. Therefore, the purpose of this article is to conduct a systematic literature review on project manager’s leadership competencies based on published empirical research studies. Methodology: We employed a systematic literature review (SLR) methodology to synthesize research in a rigorous manner and a total of 1,780 articles were identified in the first step and a final sample of 60 research studies were synthesized. Findings: Synthesis of the findings in this SLR on project manager’s leadership competencies revealed: a) there is a lack of categorization or ranking of leadership competencies; b) 20 research studies (46%) were conducted with sample sizes of less than 100; c) only a few research studies (<10%) used interview data for analysis; and d) none of the research studies reported adoption of a triangulation method. Implications/Limitations: This study prioritized project manager’s leadership competencies as ‘high priority’, ‘moderate priority’, and ‘low priority’. We recommend a sample size between 200 and 300 to produce sophisticated results and enhance the credibility, generalizability and validity of future research. Originality: Future research studies are suggested to consider systematic literature review combined with face-to-face and group interview in addition to employing triangulation methods. Besides highlighting implications for practitioners, this SLR has advanced the understanding of how to conduct systematic literature reviews in a robust manner.
