 great so Yeah, we got a bit of metrics got a bit of metrics right these guys get something done on average three days These guys get it done in 20 days Right, so it's helpful to visualize of course. We also it's also useful I mean if you can walk into team room and see if people seem to be having fun, right? There's all these soft factors that also count But here we also get a little bit of more, you know concrete data, right useful Also useful for a team to do self diagnosis, right? Let's back out a little bit Anybody here been in Japan? Anybody been inside this park? Yeah It was a while ago. I was there. I actually grew up in Japan I spent the first 16 years of my life in Tokyo and I Actually, I haven't been to this park. I don't think But people who have been told me something interesting That during that the peak season during cherry blossom when you walk into this park It's very big park is a lot of people there at having picnic So you walk into the park and there's a guard who gives you a ticket He gives you a ticket. It doesn't cost anything. There's nothing specific printed on it Just gives you a card Okay, what do I put it in my pocket? I guess and I walk and I have my picnic And then on the way out of the park the guard is collecting the tickets. Can I have it back, please? Why? The time I spent in the park that's not visible on the card. There's no time style. I think there's a time stamp Number people in the park that's my guess Because it's it's a beautiful solution, right? They're only we only have 1,000 cards on the table So when all the cards are handed out the table is empty the guard doesn't let anybody in he doesn't have to count Right and as people come out we get the cards back if somebody lost their card will print a new one Okay, big deal. So this is a simple flow control mechanism Um Kanban just means sign in Japanese just so if you tell Japanese people we do Kanban. They'd be like what we do sign But the way it's come to be used when you talk about the common systems a signaling system is visual and Limited in supply Right because there's no limit to the number of cards on the table. We lose the whole point for this park, right? So that's the Kanban system if you like All right, it is a signaling system right for supply and demand and Then the movement of supplies and services and then it's visual and it's limited in supply Or at least it should be and if it isn't your system kind of breaks down, right? This is a 10 million dollar bill or From a firm's in Bank of Zimbabwe when there's hyperinflation now if you don't limit them on a currency and in this your system You get problems just like in Kanban. I know it's a bit stretched Calling this a Kanban system, but I just want to you know help you get this in perspective, right? Okay, so Toyota Uses Kanban in fact, this is Tai Chi owner who is considered to be by many other kind of the father of
