Workforce analytics is a combination of software and methodology that applies statistical models to worker-related data, allowing enterprise leaders to optimize human resource management (HRM). Workforce analytics falls under the broad umbrella of people analytics -- also known as HR analytics. While the terms are sometimes used interchangeably, people analytics is a broad term that refers to all aspects of acquiring and managing employees, while workforce analytics is often more narrowly focused on workforce-planning issues. As with many aspects of HR, the ideas behind workforce analytics have shifted greatly as a result of technological innovation that offers far more insight into employee data. In that respect, modern workforce analytics digs deeper, wields more influence and presents itself more visually than previous incarnations.
