Background: The relevance of ESEM research to industry practitioners is key to the long-term health of the conference. Aims: The goal of this work is to understand how ESEM research is perceived within the practitioner community and provide feedback to the ESEM community ensure our research remains relevant. Method: To understand how practitioners perceive ESEM research, we replicated previous work by sending a survey to several hundred industry practitioners at a number of companies around the world. We asked the survey participants to rate the relevance of the research described in 156 ESEM papers published between 2011 and 2015. Results: We received 9,941 ratings by 437 practitioners who labeled ideas as Essential, Worthwhile, Unimportant, or Unwise. The results showed that overall, industrial practitioners find the work published in ESEM to be valuable: 67% of all ratings were essential or worthwhile. We found no correlation between citation count and perceived relevance of the papers. Through a qualitative analysis, we also identified a number of research themes on which practitioners would like to see an increased research focus. Conclusions: The work published in ESEM is generally relevant to industrial practitioners. There are a number of topics for which those practitioners would like to see additional research undertaken.
