Internationalization of multi-source feedback systems: a six-country exploratory analysis of 360-degree feedback

In the past few years, few human resource practices have received as much attention as multi-source feedback systems (MSFSs). In the US and Canada, it is estimated that over one-third of organizations are using some form of MSFS and recent surveys show that this practice is still gaining popularity. Concurrently, a substantial amount of literature has focused on the effectiveness of this performance management practice. However, while few would dispute the popularity of MSFS, relatively little has been published on the use of these systems outside North America and thus little is known about their form and effectiveness in international contexts. This paper outlines the results of an international survey of MSFS. Interview data from HR managers and consultants from Argentina, Australia, China, Slovakia, Spain and the UK demonstrate that MSFS are being implemented, in slightly different ways, in each of these six countries. The main challenges in the application of MSFS in these various countries are the communication efforts necessary before and after implementation, and the inherent difficulty in giving and receiving feedback. The results of this study also provide data as to the perceived future of MSFS in each of the countries surveyed.
