 Okay, good afternoon everyone. How many of you are design thinking practitioners here? Nobody? Okay, so I can get away by saying anything now. Okay, there is somebody here who knows, so Prasad will keep me honest. Thanks Prasad. I need someone to keep me honest here. Okay, so design thinking has been a term that's been going around in the industry for some time now. And of course Prasad comes from Infosys where one of the recent most high-profile when Vishal started the new conversations within Infosys, it kind of became more mainstream. But the whole thinking behind design thinking has kind of been going around for some time now, right? So let's spend some time in exploring it. Let me kind of roll back a little bit and see how the world was in good old days. Just to compare and contrast so that we are able to understand it a little better, right? Now if we see, there was a time 100 years back when Henry Ford said, you can have any color of car as long as it is black. Has anyone heard of that one before? So that's what Henry Ford did actually because he was able to drive the economies of scale to the level that he could, when he started and the first model T was built, it was sold at about $750. But because of the economics of mass scale production, he was able to drive it down over a period of 19 years to about $168. And he was able to do that because of multiple technological innovations and one of them being you can have any color of the car as long as it is black, which essentially meant don't ask me for any customization, don't ask me for any changes. If you like something, I don't really care because I cannot offer you. I'll offer you only exactly what I can build it in mass scale. So that was the kind of thinking behind design thinking, behind the product design there. Of course, there was a time when we said, well, you can have any telephone as long as it is an AT&T equipment. Has anyone been in telecom sector here, anyone from telecom? So there is a very famous case that happened in 1964. There was a guy of name Carter in U.S., and Carter actually wanted to put his own modem onto AT&T network, which was not allowed by law. So he filed a very famous case known as the Carter phone case, which actually the court in U.S. eventually ruled in favor of Carter by saying that AT&T does not own the network really. People are allowed to put any other equipment. So 64 was when people actually got the freedom from the monopoly of the old AT&T to really put something of there. But before that, for a long period in time, you literally had no such kind of an option available. Closer home. Let's see. I mean, these were some of the examples in U.S. Now let's see closer home what was happening there.
