What Manufacturing IT Companies Do

ERP Implementation (SAP, Dynamics 365, NetSuite)

Enterprise Resource Planning systems connect production planning, inventory, procurement, finance, and customer orders. SAP S/4HANA is the standard for large discrete and process manufacturers. Microsoft Dynamics 365 Supply Chain Management is common in mid-market and Microsoft-heavy environments. NetSuite is popular for smaller manufacturers. Implementation includes data migration from legacy systems, process mapping, custom module development, and staff training. Most go-lives take 6-24 months.

Manufacturing Execution Systems (MES)

MES sits between ERP and the shop floor. It tracks work orders, labor, material consumption, quality inspections, and machine states in real time. MES answers the question "what is happening on the floor right now" - ERP answers "what did we plan." Common MES platforms include Siemens Opcenter, Rockwell FactoryTalk, PTC Aveva, and Infor CloudSuite Industrial. MES implementation requires deep understanding of production workflows, not just software configuration.

IIoT - Connecting Machines to IT Systems

Industrial IoT connects PLCs, CNCs, robots, sensors, and other production equipment to IT networks for data collection and analysis. OPC-UA is the standard protocol for equipment-to-system communication. MQTT is common for lightweight sensor data. Ignition SCADA by Inductive Automation is a widely used platform for building IIoT dashboards and historian databases. This work requires people who understand both IT networking and OT equipment - finding a shop that does both competently is the challenge.

PLM Integration (Siemens Teamcenter, PTC Windchill)

Product Lifecycle Management systems store engineering CAD data, BOMs, change orders, and product documentation. Integrating PLM with ERP ensures that the parts your engineers design match what procurement buys and production builds. Poor PLM-ERP integration is a common source of BOM errors and production stoppages.

Predictive Maintenance with Machine Learning

Vibration sensors on spindles, thermal cameras on motors, current draw monitoring on compressors - combined with ML models that detect anomaly patterns before failure. The infrastructure requires reliable IIoT data collection (step one), a data historian, and ML engineering. The payback period for a well-implemented predictive maintenance program in a plant with critical equipment is typically 12-24 months.

Cybersecurity for OT/IT Environments

Manufacturing networks have unique vulnerabilities: old Windows XP systems running proprietary SCADA software that cannot be patched, IT/OT network convergence creating new attack paths, and engineers who prioritize uptime over security. OT cybersecurity requires network segmentation (Purdue model or ISA/IEC 62443), OT-specific endpoint security (Claroty, Dragos, Nozomi Networks), and asset inventory of industrial devices that traditional IT tools miss.

Manufacturing IT Project Costs

• ERP implementation (SAP S/4HANA, mid-size manufacturer): $500,000-$2,000,000+
• ERP implementation (Dynamics 365 or NetSuite, smaller manufacturer): $100,000-$500,000
• MES implementation: $150,000-$600,000 depending on line complexity and machine count
• IIoT connectivity project (25-100 machines): $50,000-$250,000
• OT cybersecurity assessment and segmentation: $20,000-$80,000
• Predictive maintenance program (infrastructure + ML models): $80,000-$300,000
• Ongoing managed IT services for a manufacturing site: $5,000-$25,000/month

How to Choose an IT Company for Manufacturing

1. Confirm they understand OT/IT convergence. Many IT companies claim manufacturing experience but have only done office IT work in factory settings. Ask specifically whether they have connected PLCs or CNCs to IT systems, whether they understand OPC-UA, and what OT security frameworks they follow. A company that cannot name ISA/IEC 62443 has limited OT depth.
2. Ask for references from manufacturers with your production type. Discrete manufacturing (automotive, electronics, aerospace) and process manufacturing (food, chemicals, pharma) are different enough that experience in one does not transfer automatically. A shop floor scheduling problem in a job shop is nothing like a batch record system in a pharma plant.
3. Assess their understanding of downtime costs. The IT vendor needs to understand that maintenance windows in manufacturing are planned months in advance, tied to production schedules, and that a failed update during a production run costs real money. Ask how they handle production-critical system changes.
4. Check their compliance experience relevant to your industry. ITAR for defense, FDA 21 CFR Part 11 for pharma, CMMC for DoD contractors. Missing a compliance requirement can disqualify your company from contracts or trigger regulatory action. Verify direct experience, not theoretical knowledge.
5. Evaluate ERP and MES independence. Some IT companies are certified resellers of specific ERP or MES platforms. That creates a conflict of interest when recommending solutions. Seek independent assessment before committing to a platform.
