[MUSIC] I don't know if I could call that a methodology. The first product was designed by my brother entirely, and that's when we decided, after he designed it, to start the company. I think what we do is we spend a lot of time talking to our customers, talking and reading, to more and more tech people, reading blogs, and it's a permanent and very iterative process, and all of a sudden, some ideas come up, I can't tell you why they come up at that very moment in time. So, in terms of process, I guess it's the ongoing gathering of information and with a bit of experience it's the crystallization of that knowledge that comes together at a point in time. Not really but at the same time I know the concept, I'm very familiar with it, and so, you have it in mind when you are designing and launching your company. So, I knew our business model for instance was very easy, we were going to sell or rent the equipment we were making, so there weren't any specific difficulties in there. So I would say, in the background, on my mind it was there, but I didn't specifically use it. I don't know if some of my clients would love to be called extreme users, but we had actually a very random encounter with a Ferrari engineer about three years ago, and we weren't exactly sure where we were going because initially we sold a few of our devices to museums and public spaces. And then one day, we meet that Ferrari guy who simply asks us whether our devices will run CATIA. CATIA is a very specific 3D design software, and that very question just changed the scope of what we were doing. All of a sudden, there was someone who had a very specific need that we had absolutely no idea about. So yes, we spoke to people who radically changed the way we were doing things. That's easy. The one thing I would change is I would trust my instinct much more. You hear so many people telling you that you're not going to make it, that it's impossible, that it's difficult, any time you come across a difficulty, so I would be more confident in myself. I would say, as I was saying before, trust yourself, push the boundaries and aim for something that you think even for you is too hard, because there are, you know, the chances are you're going to succeed, in every instance, you're going to make the product better. Julien gives an example of how the design thinking method actually works. Now you can already leverage design thinking methodology to refine your product or service. In the next video, we're going to discuss the S-curve and the singularity concept. Stay tuned. [MUSIC]
