With a PhD in mathematics, Keith is bringing greater discipline to the field of HR and helping HR professionals stay ahead with People Analytics. "In order to get feedback and to better understand the problems you are dealing with you need some kind of measure you can actively look at and track to tell you if the situation is improving, getting worse, or staying the same."  Yet, "one field that has always been historically quite short of good measures is human resources. . . For many decades decisions have been made in the HR context that are based on human judgment, gut instinct. . . Often decisions are being made without any underlying data or structure." For example, people often make hires based on gut feel. Yet this can lead to bias and doesn't always determine whether an individual can do the job. People Analytics takes the guesswork out of the hiring process, helping you determine what the best screens are for hiring candidates. Keith explains, "Validity is the degree to which that thing you are doing effectively predicts the outcome that you want." He shares how, when People Analytics are tied to strategic decisions, the results are powerful.
