An old management saying tells us that what we cannot measure, we cannot control. An array of new tools now promises a whole host of new quantification possibilities for companies and employee assessment methods. Data analyses, for example, can provide information on why certain members of staff are more productive than others. Algorithms help with strategic recruitment and further training measures, as well as for choosing teams for project work. Wearable technology is also becoming part of the working world: wristbands that measure employees’ stress levels and fitness trackers that sensitize staff to the benefits of a healthy lifestyle serve to boost employee satisfaction and productivity.
