How and why do we need to prototype services?

During this third Pill, Rapid Prototyping held by Marc Garcia Fortuny, students will finally learn which is one of the first step to the implementation of their projects: prototyping. So, how and why do we need to prototype services?
In these three busy days students are going to go deep in what it means the why and the how, providing an overview about existing prototyping techniques (e.g. desktop walkthrough, experience prototyping, role playing, etc) typically adopted by service designers. They will test the prototyping tools along this lectures, and understand as well, what does it mean to take a project from the idea to the pre-implementation phase, using the prototyping framework, walking through the theory, with a hands-on approach.
We are approaching the moment in which we will see students’ services become reality!
