That's a great question. And actually, during 2020, in particular, one of our internal customers, our consumer division, asked, "we wanted to do this ourselves." So one of my Regional Vice Presidents in Asia Pacific that I was working with at the time, on a number of projects that his teams are doing in the consumer, Asia Pacific sites and manufacturing, said he wanted his team to start to learn how to do this. So they could broaden scale as you were mentioning, however, CFD is a very challenging topic. And the software applications are somewhat if, unless you use them every day, it can become very difficult to remember all the steps in the procedure and process. So we embarked upon a design in working with the Siemens engineering group to build basically a user interface or a UI. And this UI was constructed in the means of, when we look at pharmaceutical and consumer products, specifically in the liquids and semi-solids area, again, is we're either dealing with Newtonian or non-Newtonian types of liquids. So the Siemens Simcenter application has tens of thousands of equations in it, but really, we're only using a certain subset. So we wanted to make sure that the UI that we're developing would target the new users that, as we started to democratize the tool, that they would be able to make decisions based upon information that they understood, not Lagrangian, not Eulerian type of mathematics, but Newtonian, non-Newtonian. So, do I have something that's fluid viscosity? Or do I have something that's more viscous, or I have a powder in a liquid type of environment? So I'm trying to understand that type of interface. So those were the types of questions we went through with the Siemens engineering team. And we basically built what I'll call this user interface to ask a user, what site were they working from? What vessel were they selecting? What type of way and that process step? What was it? Was it Newtonian? Was it non-Newtonian? Were you heating and cooling? Were are you using homogenization? In the sense of, homogenizers is when the process of making a lotion or an emulsion, so changing the form to basically make it a cream in the process. So all these questions we laid out, we also looked at the manufacturing network in J&J, is roughly about 30 to 35 sites, it changes based upon acquisitions and things happening, but 30 to 35 sites and over 150 different mixing vessels, as well as different permutations beyond that, in the sense of the internal components and the external components that are used in the process. So we built geometries, we built raw material, linked into the raw materials that are used in these products, we had the operating parameters. And basically, the end result was that any engineer would be able to go in and utilize this tool, select the equipment, select the product they were trying to make, what step it was in, which is the raw material phases, and then basically set up the simulation to run their own simulations themselves to create these manufacturing batch records or constructions that we were talking about earlier, themselves, and that they could scale that and do this. So as we built that, because we had a lot of experience, it only took us about six to eight months to deliver this, it was very, very fast. So we started in early Q1 2021. And we finished in Q4 2021. And rolled this out to the organization, the one thing we did do is, we made sure that we had the operators on board. So we identified what we'll call a key group of super users. And when we were doing the beta testing, we would have them test along with us. We're training them on CFD, we are training them on the user interface, but we're also training them on the democratization of the tool and the process. And when we rolled out, we had about 20 people we trained at the end of that six-month period to do this.
