And then, Nathan, maybe I'll add the 2 levers that we highlighted at the Analyst Day, right? So the operational excellence and then the product management portfolio optimization. So operational excellence is off to a really good start. We pushed hard on that in 2022. We started to see really good progress in 2023. And now we're really seeing the fruits of that kind of restructuring, the refocus and the operational excellence academy, which we now have trained 1,100 people.
And so as we continue to drive productivity within the manufacturing site, we're seeing those gross margins start to move up. And again, we're confident that, that will continue. And then on the product management side, this is one, as you know, has taken a longer time than I would like. It has definitely been a journey, but there's still substantial opportunities for us.
And so when we think about 2023 on product management, with the new org design, we created dedicated project management teams. And so dedicated folks within the 7 business units and then we also created a product family hierarchy. And so we've got a hierarchy of products supported by these dedicated teams. And then we have dedicated product managers now for every single product.
And then the other big effort has been the data cleanup to support this product hierarchy. I'd say we're in the early innings of that. We're focused kind of one business unit at a time, but we're seeing as we kind of really focus on that data, it now allows the product management teams to do the things that they need around pricing, selectivity, channels to market, all -- features and benefits like all that good stuff that they need to be doing as part of their job.
And then finally, is improving the process, right? So now locking in process for pricing, customer selection, channels to market and then the selectivity, which we're calling portfolio optimization, which is, all right, which products are we investing in, which products we want to continue to harvest from a cash generation perspective and not put more effort into, and then which products do we just need to stop doing.
And so again, we're kind of at the early phases of that. But going back to answer your question specifically, we expect to start seeing margin improvements from these efforts in the back half of this year, but really in earnest in 2025 and beyond. And so we feel like we still have levers to expand margins and we're still committed to that kind of 100, 200 basis points by 2027 for each of the 2 initiatives, operational excellence and product management.
