Value Proposition Design: Comment créer les produits et les services que veulent vos clients

The book presents a clear framework, but I wonder what influenced the selection of these specific methods over others. Did they test these in real-world scenarios first?

Some examples felt very industry-specific, but I'm curious if readers from different fields found them applicable or motivating.

The emphasis on understanding customer needs is obvious, but I wonder what led to that particular choice as the central theme for the book.
