People analytics refers to using analytics and data to help managers make decisions about employees. It involves collecting and analyzing large sets of talent data to make better hiring, performance, and retention decisions. However, experts warn that people analytics has limitations. Big data results can be influenced by the questions asked and algorithms used, and may miss important variables or find spurious correlations. Metrics also may not capture the most important factors for organizational success. Managing employees effectively still requires implementing analytics carefully while addressing their pros and cons.
