Does the Net Promoter Score give enough of an answer?

Many organisations have become increasing advocates of the Net Promoter Score which is based on asking customers one simple question "how likely is it that you would recommend (company name) to a friend or colleague?"  The calculations then deriving an overall result based on customer feedback between 0 and10.  Customer experience measurements and metrics are far less established and standardised and the NPS results don't help provide insights on the performance of the customers experience. The score may hide poor customer experience that is masked by a great product at a great price or other factors all influencing in this area. Certainly customer loyalty and advocacy form a part in the definition of customer experience scoring but we need to refine so it gives a tighter result around the specifics of the customer experience. Factors that should be in the frame as well as loyalty/advocacy include time (efficiency), quality of the communications, satisfaction in the result and delight in the experience (the x-factor). This forms a much more complex set of results but gives a more rounded result on the level of epic customer experience.
