Don’t be afraid (yet) but big data is coming to your job. While it is unclear whether it will make life better or worse, it is almost certain to change the way companies function.

Workday, a leading maker of cloud-based software for running corporate human resources and financial operations, has announced it is putting into its products the kind of data analysis that Netflix uses to recommend movies, LinkedIn has to suggest people you might know, or Facebook needs to put a likely ad in front of you.

In the workplace context, however, this is a much bigger deal than whether you want to see “Rango” or get tempted to try pomegranate juice. Instead of relatively trivial transactions, even in its early days this data analysis is aimed at shaping organizational charts, spotting financial behavior, or increasing competitiveness for jobs.

One version of the Workday predicts which high-performing employees are likely to leave a company in the next year; it then offers possible actions (more money, new job) that might make them stay. In another instance, expense reporting software can predict which employee populations are most likely to exceed their budgets.
