David, it's a great, great question. And it's and it's really complex. And I'll probably hand to Rob to maybe give some of the detail on it. But those five lines of work have multiple projects within each of them. I tried to term like, new parts from new suppliers. That means our R&D team is reengineering, a new part validating, verifying, putting through all the quality tests, we're seeing in our market, how incredibly important that is, and we will not compromise on quality. And then you've got to validate and verify a new supplier and get them through. And so just one of those five lines of work is an incredible amount of work for our quality, regulatory, R&D, engineering, production and manufacturing teams. And so these aren't overnight. It's not like we're just having a cell phone here or a comms chip in a consumer device. This thing a life support then has to be working all day every day. A CPAP has to work every night and we are I think able to with all that work I mean as you saw, we got 200 million, 250 million this just this fiscal year ahead of incredible growth and our supply chain pivoted to all of that. If there hadn't been this competitive recall, we as an industry ResMed would have been absolutely able to do with every single supply chain constraint that had happened throughout this. And that's just speaks to the flex and the ability to go. We have these projects that have been going nine months, I actually think they're doing well. It's hard to say, even if I gave you on each of those five lines of work, the key milestones on it, there are probably five projects within each of those. So its sort of a 5 by 5, 25 point matrix. Rob's looking at this, Jim's looking at this on a daily basis. I get the updates every second or third day. As a CEO, I used to focus all my time just on customers talking to customers talking to health insurers and showing the benefit of our therapy, spending a lot more time with supply chain than I want to but right now, that's where the urgent need is. And for the next, 3, 6, 9, 12 months is where we're going to be focused. But at the same time, we're investing in demand gen. So that as the price starts to come back, and it will, and as a competitor comes back along, we can turn that demand gen back on securing all the share gains we've got through the digital entrenchment, and then drive for future growth. But Rob, how do you summarize all the other work we're doing for David succinctly here?
