 Yutaka, what is your definition of service design? Okay, so my first, my definition of service is basically the process by which customers become certain people. So the customers are not input to the service, customers are the output. So the customers change and they become different people. So service design by definition, by my definition is about designing this process. So sometimes you have to negate customers so that they can be challenged and they can struggle to prove themselves and so on. So that's the service design for me. Really interesting, thanks. So this video is just one piece of the puzzle. Make sure to check out the other videos to get the full picture.
