IT/OT convergence integrates business IT systems (ERP, analytics, cloud) with industrial OT systems (SCADA, PLCs) to create unified data visibility and enable real-time decision-making across the manufacturing enterprise.
Definition
IT/OT convergence is the integration of Information Technology systems (ERP, MES, analytics, cloud) with Operational Technology systems (SCADA, PLCs, DCS, industrial networks) to create a unified data and control environment. Historically, IT and OT existed as completely separate domains with different teams, standards, and cultures. Convergence means breaking that separation down , connecting shop floor data to enterprise analytics, applying IT security practices to OT networks, and enabling real-time decision-making across both layers.
What this means when you're hiring
IT/OT convergence is the central narrative behind the majority of digital manufacturing roles I recruit for right now. Companies are hiring specifically for people who can sit across both worlds , who understand PLC-to-SCADA integration at a technical level and can also design cloud data pipelines and present business cases to a CFO. These people are rare. They typically come from a strong OT background who've spent time working on MES or analytics projects, or from IT backgrounds who've spent time on the plant floor.
Where candidates get this wrong
Convergence doesn't mean merging IT and OT teams , or putting IT in charge of OT. The organisations I see getting this wrong are the ones who try to apply IT governance models directly to OT without accounting for the real-time, safety-critical nature of industrial systems. The best convergence programmes I've seen create a dedicated bridge layer , often called Manufacturing IT or Digital Manufacturing , that speaks fluently to both sides without trying to subsume either.
How expectations change by level
Director-level IT/OT roles are some of the most commercially significant hires in manufacturing right now. These people own the architecture that connects £100M+ production assets to enterprise data systems. They need regulatory credibility (especially in pharma and food), vendor management experience across both IT and OT suppliers, and the political skills to navigate the IT/OT culture war that exists in most large manufacturers. The salary range for these hires reflects the scarcity and the commercial impact.
