What Is the Role of IT in Manufacturing?
A Step-by-Step Guide for Business Leaders
Manufacturing has always been about precision, consistency, and efficiency. But in today’s digital world, it’s also about intelligence — using technology to make better decisions, reduce downtime, and stay ahead of competitors. And getting your IT right can be a minefield, it’s easy to spead a fortune and make things worse than they were before.
Information Technology (IT) is now the backbone of modern manufacturing — connecting machines, people, and data to create smarter, faster, and more resilient production environments. And the right systems will put you and your team ahead of your competitors. Below we cover what the role of IT is and what it should be in Manufacturing businesses.
This guide breaks down the role of IT in manufacturing step-by-step, so business leaders can understand not just why it matters, but how to make it work effectively.
Step 1: Understand the Core Purpose of IT in Manufacturing
Before diving into specific systems or buzzwords like “Industry 4.0,” it’s crucial to understand what IT actually does in a manufacturing context (and why you should care and spend time looking at the IT in your manufacturing business).
At its core, IT enables data flow, control, and visibility across every stage of production — from raw material sourcing to customer delivery.
Key roles of IT include:
-
Integration – connecting business systems (ERP, CRM, SCM) with production control systems (MES, SCADA, PLCs).
-
Data management – collecting, storing, and analysing production data in real time.
-
Automation – replacing manual tasks with reliable, repeatable digital workflows.
-
Security – protecting intellectual property, supply chain data, and operational systems.
-
Collaboration – enabling cross-department communication and coordination.
IT’s purpose is to help manufacturers work smarter, not harder — making better use of time, talent, and technology.
Step 2: Map Out the Digital Layers of Manufacturing IT
To modernise manufacturing, it helps to visualise IT as a series of connected layers, each serving a specific purpose.
| Layer | Description | Example Systems |
|---|---|---|
| Enterprise Layer | Business planning, finance, HR, and customer management | ERP (SAP, Microsoft Dynamics), CRM (HubSpot, Salesforce) |
| Manufacturing Operations Layer | Production management, scheduling, quality control | MES (Siemens Opcenter, Ignition) |
| Control Layer | Direct machine control, process automation | PLCs, SCADA, HMI systems |
| Edge Layer | Data collection at the machine or sensor level | IoT devices, sensors, gateways |
| Cloud & Analytics Layer | Centralised data processing, AI insights, predictive analytics | Azure, AWS, Power BI, Tableau |
Conclusion: IT Is Now the Factory’s Central Nervous System
Modern manufacturing success depends on more than machines — it depends on the technology and intelligence that connect everything together.
From ERP systems to IoT sensors, IT empowers leaders to make smarter decisions, reduce waste, and stay competitive in an increasingly digital world.
