Public performance regimes are bedeviled by a paradox: they must engage the specialized knowledge of professionals who often perceive those very regimes as a threat to their autonomy. The authors use a mixed-method analysis of performance management in Danish hospitals, with separate data for managers and frontline professionals, to offer two insights into this challenge. First, the study shows that managerial behavior-in the form of performance information use-matters to the way frontline professionals engage in goal-based learning. Second, it shows that the way managers use performance data matters. When managers use data in ways that reinforce the perception of performance management as an externally imposed tool of control, professionals withdraw effort. However, when managers use data in ways that solve organizational problems, professionals engage in goal-based learning. The threat to professional values that performance regimes pose can therefore be mitigated by managers using data in ways that complements those values. Evidence for Practice • To make performance regimes work, public managers must engage professional employees whose expertise provides insight into the causes behind organizational performance, as well as the levers to improve results. • This study of Danish hospitals shows that frontline hospital professionals are more engaged in goal-based learning if their managers use performance data for problem-solving. • Professionals are less likely to engage in goal-based learning when their managers use data for reward and control. • Professionals are wary of the threats of performance regimes even as political leaders want to make those regimes work: a compromise path for both groups is to commit to aligning performance regimes with professional values.
