Podcast: IT-OT convergence at manufacturing edge delivers big productivity gains
In industrial environments, IT has typically stayed in the data center, separate from the operational technology (OT) used on manufacturing lines. But that's changing as advances in data processing and real-time analytics bring unprecedented insights and competitive advantages to the industrial edge.
"It's about doing all of that IT in places where typically IT has had a little or no involvement," says Riaan Lourens, vice president of technology at industrial solutions provider PTC. "The opportunity that exists for manufacturers today … allows them to solve problems that they face almost immediately."
To help its customers take advantage of this new opportunity, PTC has partnered with Hewlett Packard Enterprise to build out its ecosystem with everything from small gateway-level compute to hybrid and converged infrastructure technologies, enabling end-to-end solutions.
Listen to this HPE Voice of the Innovator podcast with Lourens and HPE's Tripp Partain to learn how the convergence of IT and OT at the manufacturing edge is delivering big productivity and business gains to customers and blurring "the lines between the physical and digital worlds."
Dana Gardner: Hello, and welcome to the next edition of the BriefingsDirect Voice of the Customer podcast series. I'm Dana Gardner, principal analyst at Interarbor Solutions, your host and moderator for this ongoing discussion on digital transformation success stories.
Our next edge computing trends discussion explores the rapidly evolving confluence of operational technology (OT) and Internet of Things (IoT). New advances in data processing, real-time analytics, and platform efficiency have prompted innovative and impactful OT approaches at the edge.
We'll now hear how such data analysis platforms bring manufacturers data-center caliber benefits for real-time insights where they are needed most.
To hear more about the latest capabilities in gaining unprecedented operational insights, please join me in welcoming Riaan Lourens, vice president of technology in the Office of the Chief Technology Officer at PTC. Welcome, Riaan.
Riaan Lourens, PTC
Riaan Lourens: Hey, Dana. Thanks for having me.
Gardner: We are also here with Tripp Partain, chief technology officer of IoT solutions at Hewlett Packard Enterprise (HPE). Welcome, Tripp.
Tripp Partain, HPE
Tripp Partain: Hey, Dana. Thanks a lot. I appreciate the opportunity.
Gardner: Riaan, what kinds of new insights are manufacturers seeking into how their operations perform?
Lourens: We are in the midst of a fourth Industrial Revolution, which is really an extension of the third, where we used electronics and IT to automate manufacturing. Now, the fourth is the digital revolution, a fusion of technology and capabilities that blur the lines between the physical and digital worlds.
With the influx of these technologies, both hardware and software, our customers―and manufacturing as a whole, as well as the discrete process industries―are finding opportunities to either save or make more money. The trend is focused on looking at technology as a business strategy, as opposed to just pure IT operations.
There are a number of examples of how our customers have leveraged technology to drive their business strategy.
Digital revolution in business
Gardner: Are we entering a golden age by combining what OT and IT have matured into over the past couple of decades? If we call this Industrial Revolution 4.0 (I4.0), there must be some kind of major opportunities right now.
Lourens: There are a lot of initiatives out there, whether it's I4.0, Made in China 2025, or the Smart Factory Initiative in the U.S. By democratizing the process of providing value―be it with cloud capabilities, edge computing, or anything in between―we are inherently providing options for manufacturers to solve problems that they were not able to solve before.
If you look at it from a broader technology standpoint, in the past we had very large, monolith-like deployments of technology. If you look at it from the ISA-95 model, like Level 3 or Level 4, your MES deployments or large-scale enterprise resource planning (ERP), those were very large deployments that took many years. And the return on investment the manufacturers saw would potentially pay off over many years.
The opportunity that exists for manufacturers today, however, allows them to solve problems that they face almost immediately. There is quick time to value by leveraging technology that is consumable. Then they can lift and drop and so scale [those new solutions] across the enterprise. That does make this an era the likes of which nobody has seen before.
Gardner: Tripp, do you agree that we are in a golden age here? It seems to me that we are able to both accommodate a great deal of diversity and heterogeneity of the edge, across all sorts of endpoints and sensors, but also bring that into a common-platform approach. We get the best of efficiency and automation.
Partain: There is a combination of two things. One, due to the smartphone evolution over the last 10 years, the types of sensors and chips that have been created to drive that at the consumer level are now at such reasonable price points you are able to apply these to industrial areas.
To Riaan's point, the price points of these technologies have gotten really low―but the capabilities are really high. A lot of existing equipment in a manufacturing environment that might have 20 or 30 years of life left can be retrofitted with these sensors and capabilities to give insights and compute capabilities at the edge. The capability to interact in real time with those sensors provides platforms that didn't exist even five years ago. That combines with the right software capabilities so that manufacturers and industrials get insights that they never had before into their processes.
Gardner: How is the partnership between PTC and HPE taking advantage of this new opportunity? It seems you are coming from different vantage points but reinforcing one another. How is the whole greater than the sum of the parts when it comes to the partnership?
Partnership for progress, flexibility
Lourens: For some context, PTC is a software vendor. Over the last 30 years, we targeted our efforts at helping manufacturers either engineer software with computer-aided design (CAD) or product lifecycle management (PLM). We have evolved to our growth areas today of IoT solution platforms and augmented reality (AR) capabilities.
The challenge that manufacturers face today is not just a software problem. It requires a robust ecosystem of hardware vendors, software vendors, and solutions partners, such as regional or global systems integrators.
The reason we work very closely with HPE as an alliance partner is because HPE is a leader in the space. HPE has a strong offering of compute capabilities―from very small gateway-level compute all the way through to hybrid technologies and converged infrastructure technologies.
Ultimately, our customers need flexible options to deploy software at the right place, at the right time, and throughout any part of their network. We find that HPE is a strong partner on this front.
Gardner: Tripp, not only do we have lower cost and higher capability at the edge, but we also have a continuum of hybrid IT. We can use on-premises micro data centers, converged infrastructure, private cloud, and public cloud options to choose from. Why is that also accelerating the benefits for manufacturers? Why is a continuum of hybrid IT—edge to cloud―an important factor?
Partain: That flexibility is required if you look at the industrial environments where these problems are occurring for our joint customers. If you look at any given product line where manufacturing takes place, no two regions are the same and no two factories are the same. Even within a factory, a lot of times, no two production lines are the same.
There is a wide diversity in how manufacturing takes place. You need to be able to meet those challenge with the customers to give them the deployment options that meet each of those environments.
It's interesting. Factories don't do enterprise IT-like deployments, where every factory takes on new capabilities at the same time. It's much more balanced in the way that products are made. You have to be able to have that same level of flexibility in how you deploy the solutions, to allow it to be absorbed the same way the factories do all of their other types of processes.
We have seen the need for different levels of IT to match up to the way they are implemented in different types of factories. That flexibility meets them where they are and allows them to get to the value much quicker―and not wait for some huge enterprise rollout, like what Riaan described earlier with ERP systems that take multiple years.
By leveraging new, hybrid, converged, and flexible environments, we allow a single plant to deploy multiple solutions and get results much quicker. We can also still work that into an enterprise-wide deployment―and get a better balance between time and return.
Gardner: Riaan, you earlier mentioned democratization. That jumped out at me. How are we able to take these advances in systems, software, and access and availability of deployments and make that consumable by people who are not data scientists? How are we able to take the results of what the technology does and make it actionable, even using things like AR?
Lourens: As Tripp described, every manufacturing facility is different. There are typically different line configurations, different programmable logic controller (PLC) configurations, different heterogeneous systems―be it legacy IT systems or homegrown systems―so the ability to leverage what is there is inherently important.
From a strategic perspective, PTC has two core platforms; one being our ThingWorx Platform that allows you to source data and information from existing systems that are there, as well as from assets directly via the PLC or by embedding software into machines.
We also have the ability to simplify and contextualize all of that information and make sense of it. We can then drive analytical insights out of the data that we now have access to. Ultimately we can orchestrate with end users in their different personas―be that the maintenance operator, supervisor, or plant manager―enabling and engaging with these different users through AR.
Four capabilities for value
There are four capabilities that allow you to derive value. Ultimately, our strategy is to bring that up a level and to provide capabilities solutions to our end customers across four different areas.
One, we look at it from an enterprise operational intelligence perspective; the second is intelligent asset optimization; the third, digital workforce productivity, and fourth, scalable production management.
So across those four solution areas we can apply our technology together with that of our sourced partners. We allow our customers to find use cases within those four solution areas that provides them a return on investment.
One example of that would be leveraging augmented work instructions. So instead of an operator going through a maintenance procedure by opening a folder of hundreds of pages of instructions, they can leverage new technology such as AR to guide the operator in process, and in situ, in terms of how to do something.
There are many use cases across those four solution areas that leverage the core capabilities across the IoT platform, ThingWorx, as well as the AR platform, Vuforia.
Gardner: Tripp, it sounds like we are taking the best of what people can do and the best of what systems and analytics can do. We also move from batch processing to real time. We have location-based services so we can tell where things and people are in new ways. And then we empower people in ways that we hadn't done before, such as AR.
Are we at the point where we're combining the best of cognitive human capabilities and machine capabilities?
Partain: I don't know if we have gotten to the best yet, but probably the best of what we've had so far. As we continue to evolve these technologies and find new ways to look at problems with different technology, it will continue to evolve.
We are getting to the new sweet spot, if you will, of putting the two together and being able to drive advancements forward. One of the things that's critical has to do with where our current workforce is.
A number of manufacturers I talk to―and I've heard similar from PTC's customers and our joint customers―is you are at a tipping point in terms of the current talent pool, with those currently employed and those getting close to retirement age.
The next generation that's coming in is not going to have the same longevity and the same skill sets. Having these newer technologies and bringing these pieces together, it's not only a new match-up based on the new technology; it's also better suited for the type of workers carrying these activities forward. Manufacturing is not going away, but it's going to be a very different generation of factory workers and types of technologies.
The solutions are now available to really enhance those jobs. We are starting to see all of the pieces come together. That's where both IoT solutions―but even especially AR solutions like PTC Vuforia―really come into play.
Gardner: Riaan, in a large manufacturing environment, only small iterative improvements can make a big impact on the economics, the bottom line. What sort of future categorical improvements value are we looking at? To what degree do we have an opportunity to make manufacturing more efficient, more productive, more economically powerful?
Tech bridges skills gap, talent shortage
Lourens: If you look at it from the angle that Tripp just referred to, there are a number of increasing pressures across the board in the industrial markets via the workers' skills gap. Products are also becoming more complex. Work spaces are becoming more complex. There are also increasing customer demands and expectations. Markets are just becoming more fiercely competitive.
But if you leverage capabilities such as AR―which provides augmented 3D work instructions, expert guidance, and remote assistance, training, and demonstrations―that's one area. If you combine that, to Tripp's point, with the new IoT capabilities, then I think you can look at improvements such as reducing waste in processes and materials.
We have seen customers reducing by 30 percent unplanned downtime, which is a very common use case that we see manufacturers target. We also see reducing energy consumption by 3 to 7 percent at a very large ship manufacturer, a customer of PTC's. And we're generally looking at improving productivity by 20 to 30 percent.
By leveraging this technology in a meaningful way to get iterative improvements, you can then scale it across the enterprise very rapidly, and multiple use cases can become part of the solution. In these areas of opportunity, very rapidly you get that ROI.
Gardner: Do we have concrete examples to help illustrate how those general productivity benefits come about?
Joint solutions reduce manufacturing pains
Lourens: A joint customer between HPE and PTC focuses on manufacturing and distributing reusable and recyclable food packaging containers. The company, CuBE Packaging Solutions, targeted protective maintenance in manufacturing. Their goal is to have the equipment notify them when attention is needed. That allows them to service what they need when they need to and focus on reducing unplanned downtime.
In this particular example, there are a number of technologies that play across both of our two companies. The HPE Nimble Storage capability and HPE Synergy technology were leveraged, as well as a whole variety of HPE Aruba switches and wireless access points, along with PTC's ThingWorx solution platform.
The CuBE Packaging solution ultimately was pulled together through an ecosystem partner, Callisto Integration, which we both worked with very closely. In this use case, we not only targeted the plastic molding assets that they were monitoring but the peripheral equipment, such as cooling and air systems, that may impact their operations. The goal is to avoid anything that could pause their injection molding equipment and plants.
Gardner: Tripp, any examples of use cases that come to your mind that illustrate the impact?
Partain: Another joint customer that comes to mind is Texmark Chemicals in Galena Park, Texas. They are using number of HPE solutions, including HPE Edgeline, our micro data center. They are also using PTC ThingWorx and a number of other solutions.
They have very large pumps critical to the operation as they move chemicals and fluids in various stages around their plant in the refining process. Being able to monitor those in real time, predict potential failures before they happen, and use a combination of live data and algorithms to predict wear and tear, allows them to determine the optimal time to make replacements and minimize downtime.
Such uses cases are one of the advantages when customers come and visit our IoT Lab in Houston. From an HPE standpoint, not only do they see our joint solutions in the lab, but we can actually take them out to the Texmark location and Texmark will host and allow you them see these technologies in real time working at their facility.
Similar as Riaan mentioned, we started at Texmark with condition monitoring and now the solutions have moved into additional use cases―whether it's mechanical integrity, video as a sensor, and employee safety-related use cases.
We started with condition monitoring, proved that out, got the technology working, then took that framework―including best-in-class hardware and software―and continued to build and evolve on top of that to solve expanded problems. Texmark has been a great joint customer for us.
Gardner: Riaan, when organizations hear about these technologies and the opportunity for some very significant productivity benefits, when they understand that more and more of their organization is going to be data driven and real-time analysis benefits could be delivered to people in their actionable context, perhaps using such things as AR, what should they be doing now to get ready?
Lourens: Over the last eight years of working with ThingWorx, I have noticed the initial trend of looking at the technology versus looking at specific use cases that provide real business value, and of working backward from the business value.
My recommendation is to target use cases that provide quick time to value. Apply the technology in a way that allows you to start small, and then iterate from there, versus trying to prove your ROI based on the core technology capabilities.
Ultimately understand the business challenges and how you can grow your top line or your bottom line. Then work backward from there, starting small by looking at a plant or operations within a plant, and then apply the technology across more people. That helps create a smart connected people strategy. Apply technology in terms of the process and then relative to actual machines within that process in a way that's relevant to use cases―that's going to drive some ROI.
Gardner: Tripp, what should the IT organization be newly thinking? Now, they are tasked with maintaining systems across a continuum of cloud-to-edge. They are seeing micro data centers at the edge; they're doing combinations of data-driven analytics and software that leads to new interfaces such as AR.
How should the IT organization prepare itself to take on what goes into any nook and cranny in almost any manufacturing environment?
IT has to extend its reach
Partain: It's about doing all of that IT in places where typically IT has had a little or no involvement. In many industrial and manufacturer organizations, as we go in and start having conversations, IT really has usually stopped at the data center back-end. Now there's lots of technology in the manufacturing side, too, but it has not typically involved the IT department.
One of the first steps is to get educated on the new edge technologies and how they fit into the overall architecture. They need to have the existing support frameworks and models in place that are instantly usable but also work with the business side and frame up the problems they are trying to solve.
As Riaan mentioned, being able to say, "Hey, here are the types of technologies we in IT can apply to this that you [OT] guys haven't necessarily looked at before. Here's the standardization we can help bring so we don't end up with something completely different in every factory, which runs up your overall cost to support and run."
It's a new world. And IT is going to have to spend much more time with the part of the business they have probably spent the least amount of time with. IT needs to get involved as early as possible in understanding what the business challenges are and getting educated on these newer IoT, AR, virtual reality (VR), and edge-based solutions. These are becoming the extension points of traditional technology and are the new ways of solving problems.
Gardner: I'm afraid we'll have to leave it there. We have been discussing the rapidly evolving confluence of OT and the IoT. And we have learned how data processing, real-time analytics, and platform efficiency are all prompting new OT approaches at the very edge of manufacturing.
