The document discusses the importance of measuring customer satisfaction through Net Promoter Score (NPS). It notes that customer experience is shaped by every interaction and that 56% of unhappy customers will tell others about their poor experiences. NPS measures customer satisfaction and likelihood to recommend by asking customers to rate how likely they are to recommend a company to friends. The system sorts customers into promoters, passives, and detractors to identify problem areas and drive improvements. Regular NPS tracking helps organizations prioritize customers and change behaviors to keep a focus on delivering positive experiences.
