 So Jerry, what is service design? As I said, service design is the design of services, but it's a deep understanding of a system that is at play. And that involves behavioural understanding of what's occurring inside an organisation. It's the sequencing of events that's currently in operation in an organisation or in a new organisation. It's the, I guess, to NAB, Patrick Wazelbaum and Chris Rizdoms. It's an orchestration. And I really like that sort of definition. It's an orchestration and it's a thing of beauty. I mean, whenever you see something happen, like we know as practitioners that a lot of work went into making those things happen. For instance, I was flying from Dublin to London last night and I got a flight at seven o'clock, except the flight didn't take off until 9.40 or 10 o'clock. And it dropped me at South End as opposed to London City, which is about an hour and a half outside of London. Nobody, and I actually sit there and laugh because these are the things that I talk about at conferences. And I started taking photographs of all the problems and stuff. But one of the cases was the phone number that they provided for additional information was at 10 o'clock at night. There was no one answering the phone because it was out of business hours. I mean, it's thinking of how you can break a system and how you can break this design. It's being destructive with service design. It's really getting deep into how we can abuse services and getting that deep understanding of what it is and how we can actually make it better. So this video is just one piece of the puzzle. Make sure you check out some of the other videos to get the full picture. And if you want to learn how to explain service design without confusing people, check out the free course that I've got for you over here or check the link down below in the description. Thanks for watching and I look forward to seeing you in the next video.
