Doesn a PCS have the capacity to dehumanize the employee?
In fact it’s exactly the opposite. Instead of forcing people to learn lots of discrete facts that will change over time, for example having to learn the features and benefits of hundreds of products, you can let the PCS handle all the facts and let the human focus on more important things like relating and communicating with the customer. It allows you to focus on hiring people for their soft skills such as interpersonal and analytical skills rather than just on how much someone can remember.
