Demonstrating the success of the Net Promoter Score methodology to skeptical senior management can sometimes be difficult. It is especially so if you are trying to prove it before your organisation has implemented any changes.
One way to prove the value of NPS® is to use external success stories and case studies to show what has been done by other organisations. Unfortunately, finding those case studies can be very difficult.
To try to overcome this issue, I have decided to create a list of case studies and references that are public domain. This blog post will be updated whenever I have new material.
This is an adjunct to my other source list post: Net Promoter Score Research: the “for” and “against” list
If you have results or a link to a published article, presentation or other source please use the comment box below to let me know and I’ll add it to this list so we can all benefit.
