 I'm Alex Nisbit and this is the Service Design Show. So this idea of customer performance or spectator performance that can also be applied to think about the airport. So oftentimes you're in a hurry, you don't know which way to go, the gate may be changed. But you really need to get to that gate on time and if you can do that, then you're more likely to buy a coffee or maybe some last minute duty free. But especially you're going to be a happy passenger if you like, a high-performance passenger. And that's what the airlines like, they like us when we're flying to be happy, to be punctual. But that means that the airport has got to help us get to the right place at the right time. And it works for hospitals, it works if you're visiting a city for the first time as a tourist. It works, so this idea of high performance for a customer.
