This document outlines the results of a survey conducted with various line managers and HR professionals to understand their perceptions of HR effectiveness. It finds that line managers generally rate HR professionals lower on effectiveness than HR professionals rate themselves. Specifically, line managers feel HR has less quality/business focus, efficiency focus is more on activities than outcomes, there is a lack of collaboration between HR and lines, and HR is more beholden to the corner office. HR professionals acknowledge some of these issues but to a lesser extent. When comparing factors leading to negative vs positive perceptions, line managers see more negatives regarding HR while HR sees more positives about themselves. Overall there are both similarities and differences in how the two groups view the drivers of perceptions of HR.
