Meta-analysis is a research method for systematically combining and synthesizing findings from multiple quantitative studies in a research domain. Despite its importance, most literature evaluating meta-analyses are based on data analysis and statistical discussions. This paper takes a holistic view, comparing meta-analyses to traditional systematic literature reviews. We described steps of the meta-analytic process including question definition, data collection, data analysis, and reporting results. For each step, we explain the primary purpose, the tasks required of the meta-analyst, and recommendations for best practice. Finally, we discuss recent developments in meta-analytic techniques, which increase its effectiveness in business research.
