PurposeNotwithstanding that evidence-based human resource management (EBHRM) is gaining more ground in governmental institutions, it is still lacking a clear and research-driven conceptualisation (Marler and Fisher, 2013). Therefore, this study seeks to establish a fundamental clarifying concept of EBHRM by using a systematic literature review.Design/methodology/approachThis method builds on an intensive scanning of 2,584 (interdisciplinary) articles, collected from Web of Science and Scopus. Eventually, 50 articles met the predetermined inclusion criteria and were analysed. The most recent conceptualisation of evidence-based management in the literature has served as a guideline to compare the review results and further scrutinise the differences and similarities (Barends et al., 2014; Barends and Rousseau, 2018; Rynes and Bartunek, 2017).FindingsThis has enabled us to elaborate a comprehensive conceptualisation. The articles were divided into two groups, one group (n = 31) has Rousseau et al. as a reference, the other (n = 19) did not, and used various definitions. Three themes were identified: evidence-based research methods (n = 30), specific skills (n = 36) necessary to apply an evidence-based strategy and a link with the academic-practice gap (n = 25).Practical implicationsBased on the results, we recommend adding two dimensions to strengthen the current conceptualisation: a first dimension referring to how evidence-based management can be established (i.e. which methods and skills are necessary) and a second dimension referring to the why of evidence-based management in an organisation (reducing the academic-practice gap).Originality/valueThis paper starts from a systematic review approach unlike previous research in the field to contribute to the further conceptualisation of EBHRM (Rynes and Bartunek, 2017).
