You have been observing that since the past few years, happy employees are the key profit generators of your company and in all these years, you noted down the happiness index of all your employees and their productivity. Now you have tons of this employees' data just lying around in excel files and you just recently heard "Data is the new oil. The companies that will win are using math." You are wondering if you could also win by somehow mathifying this data that could predict the productivity of your new employees based on their happiness index. So that it would become easier for you to identify your least productive employees (and then supposedly fire them-just supposedly).
