 I would say I think it's difficult to pinpoint the biggest challenge if the whole process, the whole transport is consisting of a number of links in the chain and the whole chain has to be to its best to have the safe and secure transport. So maybe that is the biggest challenge actually to giving everything, every single bit of the chain to being at the best every time from the beginning where the customers have to give us the information on what they're sending to us, to the EDI exchange between the different parties and in the end also to the operational processes. In relation to what we benefit from these events like this one, I think there's two major benefits. One would of course be that we managed to get the same common view and common understanding on how things are developing a global model together. But the second one is of course also, it would always be inspirational for us to hear what our colleagues, stakeholders and so on do around the world. It inspires us to look at our things back home, we may adjust things, continuous improvement is an important part of our everyday life and we need to keep on finding them, what do you call it? It's the small things that helps us do that.
