Net Promoter Score (NPS)

A net promoter score (or NPS) is a measure of customer loyalty and satisfaction, by way of survey.  Real customers / users are asked to share how likely they would be to recommend a particular product, service, or company.  Those scores are then used to calculate the NPS, giving an indication of the general sentiment towards the survey subject.  Some have argued that, if someone is aware of the scoring system, this affects how they will score the subject.  For this reason, no details of the scoring system are provided here.
