Dave Gray, co-author of the great book, Gamestorming, and one of Rosenfeld Media's strategic advisors has just written an excellent round-up of the rationale for service design in his Dachis Group blog post, Everything is a Service.

Dave writes about the argument and mindset from both cultural and business change perspectives – what we've been calling the "moral philosophy" of service design as a shorthand between ourselves recently. It mirrors much of what we've written in the opening chapter of our book and nods at some of the things we'll be talking about in the conclusion. Accompanied by some of Dave's seemingly effortless but excellent drawings, it really is well worth a read. A stand out sentence for me – clearly very American in context – was in the section where he talks about cars: "If a car can be a service, anything can."

Gamestorming now has an iPhone app, which just goes to show that books are services too (if Rosenfeld's publishing approach hadn't already convinced you of that - don't forget, "Our authors are brilliant, but write at their own unique, unpredictable paces." Ahem).
