This chapter provides an expanded view of performance management that goes beyond the traditional I/O psychology focus on performance measurement. It discusses performance management as including what happens before and after performance is measured, considering the role of time and context. It also notes the science-practice divide in performance management, where practitioner interests in topics like talent management and leadership development are not well addressed in academic research, which tends to focus more on topics like performance appraisal. The chapter argues this divide needs to be addressed to better help practitioners implement research-based performance management.
