Had to force myself to get through this book. I read it for work reasons. There are some really interesting stories included and I found it entertaining to look up via LinkedIn the key Tesco staff involved and other people mentioned to see what they are up to now. Most of them are now at director level which says something.
I'd sum this book up as an insight into how to use loyalty data laterally to extract true value out of it. It was definitely worth reading, I'm glad I did.
