Evaluating research is an established part of the research process, as funding agencies and governments seek to raise its quality and performance. The United Kingdom's Research Excellence Framework 2021 (REF2021) was the eighth formal assessment of research in UK universities. In Business and Management Studies (B&M), Sub-Panel 17, 108 universities submitted 16,038 research outputs and 539 impact case studies covering the period 2014-2020. Submissions were assessed by a panel of academic researchers and research users, nominated by a range of academic constituencies. The outcome was that the quality of UK research in B&M continues to improve since REF2014. The quality profile for REF2021 had 79% of research assessed as 3* (internationally excellent) and 4* (world-leading). The paper explains and reports on our experiences of the peer review process, analyses the outcomes and discusses the state of research within the discipline. Subsequently, we consider the wider implications of the REF process, its methodologies and impacts, contributing to the debate about research quality in universities. The paper concludes with support for peer review and expresses caution against the automation of research quality assessment.This paper draws upon the work of the United Kingdom's Business and Management Studies Sub-Panel 17 of the Research Excellence Framework (REF2021), and the authors would like to thank sub-panel members for their comments on an earlier draft of this paper. We would also like to acknowledge the helpful feedback from the anonymous referees, particularly in relation to broadening the scope and discussion of the paper. The views expressed are those of the authors. cesses and outcomes of the B&M sub-panel in the United Kingdom's Research Excellence Framework (REF2021), providing an analysis of the results and a discussion of their wider ramifications. Performance measurement of university research is undertaken in many countries at periodic intervals using a range of performance-based research funding systems (PRFs) (Guena and Martin, 2003). Sivertsen (2017) notes that, as an early adopter of research evaluations, the best practice developed in the United Kingdom has affected the design and development of evaluation approaches employed in other countries.A distinction is sometimes made between evaluation exercises that focus on research quality and/or those that also consider the consequences
