Isn't there a chance that it could be problematic (or at least challenging) to reduce employee performance to a single numeric value? To me it feels like employee performance is an ongoing, continuous, qualitative and subjective measurement that only a person's peers can really describe -- probably in their own varying and approximate terms. In other words: less "NPS 6", and more: "would consider as a code reviewer during my quest to sort all variables based on string length ... but appears to make poor choices regarding bringing aromatic food into the cubicle farm".
