Net Promoter Score (NPS) in product management is like a child's reaction to food. It tells you how people feel, but it's what you do with that feedback that matters.
Customers give feedback in different ways, just like a child's varying reactions to food.
Not all fixes for customer dissatisfaction work instantly. It is a process of learning what works and what doesn't.
Great products create word-of-mouth promotion as satisfied customers share their positive experiences.
