15. What’s the smallest, simplest thing we can do? Retain high value customers Like this example… Common features of defectors?

16. Is it useful & actionable? Retain high value customers Like this example… Common features of defectors?

17. Repeat!Retain high value customers Like this example… Common features of defectors? Shopping behaviors of defectors?

18. Retain high value customers Like this example… Common features of defectors? What leads to customers leaving? Shopping behaviors of defectors? What do defectors say about us? Customers’ sentiment before defecting? What encourages customers to stay? Do incentives reduce defection rates?

19. Problem solved or continue? What leads to customers leaving? Like this example… Common features of defectors? Shopping behaviors of defectors? What do defectors say about us? Customers’ sentiment before defecting? What encourages customers to stay? Do incentives reduce defection rates?
