While we may never convert change management into a “hard science,” some firms are already benefiting from the potential that data-driven techniques offer. One of the key enablers is the analysis of email traffic and calendar metadata. This tells us a lot about who is talking to whom, in what departments, what meetings are happening, about what, and for how long. These sorts of analyses are helping EY, where some of us work, by working with Microsoft Workplace Analytics to help clients predict the likelihood of retaining key talent following an acquisition and to develop strategies to maximize retention. Using email and calendar data, we can identify patterns around who is engaging with whom, which parts of the organization are under stress, and which individuals are most active in reaching across company boundaries.
