Yes. I mean I think there's a couple of words that go together here. There's the digital thread idea, which means data created upstream is used multiple times downstream. Then there's the model-based idea, which says, by the way, let's make sure this data is 3D models, not 2D drawing, so model-based digital thread and then closed loop means, let's make sure that things we find in the manufacturing process, for example, using DPM get reflected into changes upstream, either in the product itself or in the manufacturing plan. And then let's make sure that what we find when the products all the field at the customer site, for example, IoT, smart connected products, that is likewise being funnel back end, ultimately, upstream, maybe into the product, maybe into the manufacturing process, maybe into the service process. But let's have these feedback loops. So I think this concept PTC has of a model-based closed-loop digital thread is very powerful, and I'd say pretty unique. And yes, I'll talk a lot about that at LiveWorx. If I know it will be a kind of theme throughout. So it allows us to cross-sell in a lot of directions. We talked about Codebeamer and Windchill. Well, there's going to be a similar conversation between Windchill and ServiceMax and between ServiceMax and Servigistics and ServiceMax and ThingWorx IoT. So we like this idea of a lot of products that are very compelling could be sold stand-alone as the tip of the spear but then integrated into this digital thread so that they could -- kind of better together. Better together, but you don't have to buy it all. If you want to use ServiceMax with some other PLM system, fine, we know how to make that work. And you have to be that way because it's practical. Customers don't throw out all their technology and switch like stock and barrel. They look at what they have and they want to systematically over time, upgrade it. And so we get in there, we might win with Windchill and then we might win with Codebeamer, and then we might introduce ServiceMax, and that's kind of how we've built our whole growth story over the last decade is by really perfecting these cross-sell motions.
