Information Technology (IT)

Information Technology (IT) commonly refers to the systems, infrastructure, software, and services used to store, process, transmit, and secure digital information within an organization. In industrial and manufacturing environments, IT typically covers business and enterprise systems such as email, office productivity tools, ERP, corporate networks, data centers, cloud platforms, and security tooling that protect these assets.

Scope and typical components

IT in a manufacturing company often includes:

• Enterprise applications such as ERP, PLM, CRM, HR systems, and financial systems
• Corporate networks, data centers, cloud environments, and remote access services
• End-user devices such as laptops, desktops, mobile devices, and their operating systems
• Shared services such as email, identity and access management, directory services, and backup
• Cybersecurity controls focused on confidentiality, integrity, and availability of business data

IT organizations are usually responsible for architecture, procurement, configuration, support, patching, and lifecycle management of these systems. They also maintain policies for topics such as network access, account management, encryption, and change management.

IT in relation to OT and manufacturing systems

In industrial operations, IT is often contrasted with Operational Technology (OT). While IT focuses on information processing and business workflows, OT focuses on monitoring and controlling physical processes, such as production lines, utilities, and safety systems.

Typical interactions between IT and OT include:

• Integrations between ERP and MES or other plant-level systems for orders, inventory, and production data
• Shared or segmented networks connecting enterprise systems to plants and sites
• Security services such as identity, logging, and incident response applied to OT environments
• Data integration and analytics platforms that combine plant data with enterprise data

In regulated or safety-critical manufacturing, IT staff working with OT environments need awareness of constraints such as high availability requirements, long equipment lifecycles, formal change control, validation, and the impact of downtime on safety and compliance.

Common confusion

IT vs OT: IT deals primarily with business information systems, while OT deals with control systems and equipment that directly affect physical processes. Some technologies, such as industrial edge servers or plant historians, may involve both IT and OT responsibilities, and organizations often define clear boundaries and shared governance for these areas.

IT vs ICS/SCADA: Industrial Control Systems (ICS) and SCADA platforms are usually considered OT, even though they run on computing hardware and networks. IT may manage underlying infrastructure, but the control logic, safety impacts, and operational policies are usually owned by engineering or operations.

Derived-from context: IT staff in OT environments

When IT personnel support or integrate with OT systems, effective practice commonly includes structured exposure to plant operations, an understanding of safety and availability constraints, awareness of long asset lifecycles, and adherence to change-control and validation processes. This context influences how IT policies and tools are adapted for production environments.
