IT/OT Convergence 101
Bridging the gap between physical and digital capabilities in manufacturing environments creates a significant competitive advantage. Among the benefits: increased agility and flexibility, lower costs, less downtime, better productivity and faster, smarter decisions. This convergence will displace companies that don’t embrace it, and many are behind. Their manufacturing operations still exist in two completely separate worlds: the traditional, physical world of operational technology (OT) and the data-driven world of digital technology (IT). While there are challenges that must be overcome to bring the two together, the risk of not doing so is quite real — especially when competitors are making the leap.
IT/OT Convergence is a key piece of Intelligent Manufacturing
What is IT/OT Convergence?
Simply put, IT/OT convergence is the integration of IT systems with OT systems. It is central to today’s intelligent manufacturing and industrial IoT initiatives. To best understand bringing these two systems together, it’s important to first understand the core parts of each system.
IT systems manage data.
They encompass hardware, software and applications used for the creation, storage, security, sharing and processing of data. This is the realm of data centers, cloud computing and the internet. IT systems tend to be broadly and intricately networked.OT systems control the physical world.
OT encompasses hardware and software that detect or cause a change through the direct monitoring and/or control of industrial equipment, assets, processes and events within a facility. OT systems may use sophisticated supervisory control and data acquisition systems (SCADA), distributed control systems (DCS), programmable logic controls (PLCs) and other technologies, but they aren’t typically networked beyond the walls of the facility.
The disadvantages of keeping IT and OT separate
Traditionally, IT and OT systems have operated in separate spheres. Today, however, the rapid proliferation of connected “things” (IIoT) has increased the appetite for real-time data and analysis exponentially. Innovations in edge computing, artificial intelligence, machine learning and machine-to-machine communications continue to advance what’s possible. Keeping IT and OT separate puts a business at a disadvantage by limiting a company’s ability to:
- Identify opportunities and pinpoint risks using the vast amount of data produced by sensor-laden devices, equipment and machinery. Instead, they have to aggregate data from different sources manually.
- Take a comprehensive and coordinated approach to cybersecurity to lessen the opportunity for cybercriminals to take advantage of vulnerabilities.
- Use digital twins to proactively assess how environmental factors, adverse events, workflow changes or labor fluctuations will impact product quality or production.
- Use augmented reality (AR) in a connected system to maintain operations remotely, enhance training simulations and guide people through complex processes and repairs.
- Use predictive maintenance analysis to avoid potential downtime caused by malfunctioning machines.
- Leverage cloud services and edge computing for enhanced analytical and data storage capabilities.
Companies must now execute effectively on the priorities they have laid out in the areas of remote operational capabilities, data-driven decision making, and resiliency across their technology and operational capabilities to support volatile market dynamics.”

The advantages of IT/OT convergence
Integrating IT and OT into a seamless, holistic system that encompasses production and business functions gives companies access to real-time, actionable data and analytics organization-wide, enabling them to:
- Make better decisions faster
- Automate processes effectively
- Anticipate and solve for production and supply chain issues
- Scale production up or down on demand
- Minimize the impact of planned downtime
- Identify areas of underutilization
- Centralize asset tracking
- Simplify process control
- Improve service-level agreements (SLAs) and regulatory compliance
- Manage operations from a centralized dashboard
IT/OT convergence strategy: overcoming challenges
Successful IT/OT convergence requires companies to be deliberate about education, cross-training and collaboration. Each side needs to be well-versed in the day-to-day activities, needs, challenges and risks of the other, and they have to work together productively to benefit the organization as a whole. Shared responsibility, defined processes, clear KPIs and a commitment to open communication will enable teams to clearly assess and successfully overcome IT/OT convergence challenges. Here are some of the most-often encountered IT/OT convergence challenges and a few ways to solve for them.
| Challenge |
Issue |
Solution |
| Legacy equipment |
The lifetime of IT equipment is generally 3-5 years. Industrial equipment can still be in good shape decades after deployment — with decades-old technology on board. |
Layer an IT data exchange system on top of an OT system to gather and process data without having to make modifications to existing operations hardware. |
| Device capabilities |
Some edge devices may not be as adept at receiving and acting upon incoming data as they are at generating and sending it. |
Engage an experienced applications developer, because customized applications will always be necessary for effective edge computing. |
| Compatibility |
A lack of shared standards or protocols may inhibit the ability of IT and OT systems to work symbiotically. |
Choose hardware and software suppliers that support a wide variety of industrial protocols, standard APIs and modern IIoT protocols such as MQTT. |
| IT systems capacity |
All that data streaming from industrial machines and other edge devices has to be ingested, stored, analyzed and distributed to be of any use. |
Identify and engage an operations and an IT lead early on. Cooperation is essential when deciding how data will be managed. |
| Scalability |
Manufacturing often has to turn on a dime to accommodate changing customer needs, supply chain problems, vendor issues, etc. |
Establish clear expectations and accountability with everyone who will be affected by a change. Implement processes to get the right information to the right people at the right time. |
| Security |
Anything connected to the internet becomes fair game for a debilitating cyberattack, and more "things" = a greater attack surface. |
Reduce the number of vulnerabilites a hacker can exploit by creating strong boundaries between business and process control networks. Deploy mesh cybersecurity architectures to secure individual devices. |
| Redundancy/failover |
Critical operations cannot afford to deal with IT system outages. "Five-nines" uptime — 99.999% — is essential. |
Design redundancy into data exchange systems. Reliable, resilient hybrid edge/cloud architectures enable fallback data exchange and processing at the edge or in the cloud. |
| Skills gap |
Many organizations lack the skills or expertise to successfully integrate their IT and OT systems. |
Engage an experienced systems integrator to work side by side with a manufacturing engineer to design the data exchange and analytics system. Use no-code or low-code applications to empower more people. |
