What is service design?

From what I understand my thesis, Organizing Principle is very much in-line with service design thinking. I was introduced to the above book by Delia Dumitrescu, Lead Innovation Architect at Trendwatching. On the company’s website they have a nice video explain what service design is.

So far what i’ve come to understand is that service design is an organizing concept that helps distinguish goods and services, but more importantly it is a way of raising new questions of what value is. It causes us to looking at the interdependent relationships between an object and a consumer and how each relate to one another. In doing so it helps us understand which touchpoints can have the most value and tells us which areas are most in need of design.
