In order to excel at employee management and retention, a number of firms are using HR based business analytics. Convenience store chain Wawa uses a software which not only analyzes but also predicts performances of its employees across its 700 plus stores. This goes a long way in improving store sales. SAP has devised an application known as Success-Factors that is cloud based and helps assess talent levels of individual employees. HR metrics and analytics tools also help out in decoding questions such as best candidates for particular position, who should be recruited early and in whose case chances are higher to accept offers. And then there is Workaday whose predictive analytics recommends candidates to prospective employers using an algorithm similar to what Netflix uses to suggest movies to users.
