What I found useful

This book gives a great insight into the economy of intangibles – design, branding, software, knowledge etc – something that is often ignored.

A lot of the thinking is applicable to services and the service economy.  In particular, we can use the author’s 4 S model of intangibles to understand services and service innovation.  These 4 S’s are: scalable, sunk costs, spillover and synergies.

If you don’t have the book, their Talk at Google is a good taster before you do purchase it.
