Once upon a time, organizations were made up of people. Today they consist of data. As companies have learned to mine their data to better identify new opportunities, improve predictions, and make better decisions, interest has shifted from the humans who do the work to data on what they do during work hours (e.g., how may emails they sent, how many people they talked to, how many breaks they took). In particular, employee data is being used more and more in human resources management (HRM) — and, more recently, people analytics (PA) — and workers are increasingly being defined in terms of their data.
