The RIS customer survey system, formerly NPS, is a flawed way to evaluate employees. Customers often register complaints about Verizon's service, their phone plan or other issues that are outside of employees’ control. Glitches in the surveys also mean that employees can be evaluated by customers they didn't serve or only very briefly interacted with. Verizon Wireless knows about these problems, yet these surveys still factor heavily into employee evaluations and managers are required to hold unnecessary and often humiliating coaching sessions. Managers have lots of tools to evaluate employees including sales, store reviews, customer volume and more. It's time to stop using error-prone RIS surveys.
