When we use the term Voice of the Customer (VoC), most people will automatically think of Net Promoter Score (NPS) or some form of customer satisfaction measurement tool.
VoC actually refers to the way a brand captures customer feedback, and how they analyse and interpret these customer insights to improve the overall customer experience (CX).
Not all brands are effective in using VoC. When capturing customer feedback, more often than not, a brand’s core objective is actually to learn how great the customer thinks they are! You will be familiar with the questions; would you recommend us? would you visit us again?
These questions may help the brand boost their NPS score, but the responses are based only on customer intent. The power of VoC goes much deeper than this.
