    The Manufacturing IT "Health Score" Tool

    By Robert Burke

    Executive Summary

    Southeast manufacturers face unique IT challenges at the intersection of production uptime, OT security, and supply chain connectivity. The Manufacturing IT Health Score assesses your plant-floor infrastructure across five critical dimensions—network resilience, OT segmentation, backup readiness, IoT security, and JIT system uptime—delivering a letter grade with specific improvement recommendations.

    The Manufacturing IT "Health Score" Tool

    Key Takeaways

    • Assesses five critical manufacturing IT dimensions in under 10 minutes
    • Delivers an A–F letter grade with specific improvement recommendations
    • Identifies "ghost" security risks in OT/IoT network segments
    • Evaluates JIT production system resilience and failover capabilities
    • Provides a prioritized action plan to move from C-grade to A-grade

    Manufacturing IT is fundamentally different from office IT. While a law firm experiences a slow email server as an inconvenience, a manufacturer experiences a network outage as a production stoppage—with costs measured in thousands of dollars per hour of lost output.

    The Five Dimensions of Manufacturing IT Health

    The Core12 Manufacturing IT Health Score evaluates your plant-floor infrastructure across five critical dimensions, each scored on a 20-point scale for a total possible score of 100.

    Dimension 1: Network Resilience (20 points)

    Network resilience measures your ability to maintain connectivity during ISP outages, equipment failures, and traffic surges. Key assessment factors include:

    • Redundant WAN connectivity: Do you have multiple ISP connections with automatic failover? Manufacturers running on a single ISP circuit face catastrophic risk—a single fiber cut can halt production entirely.
    • SD-WAN implementation: Is your network intelligent enough to route production traffic through the best available path automatically? Application-aware routing ensures that ERP, MES, and EDI traffic receives priority over general internet usage.
    • Internal network redundancy: Do your core switches have redundant power supplies and stacking configurations? A single switch failure in a flat network can take down an entire production floor.

    Dimension 2: OT/IT Segmentation (20 points)

    OT/IT segmentation evaluates the separation between your production operational technology networks and corporate IT networks:

    • Network segmentation: Are PLCs, HMIs, and SCADA systems on isolated VLANs with controlled access from the corporate network? Flat networks where an accountant's laptop shares a broadcast domain with CNC controllers represent a critical security failure.
    • Industrial DMZ: Is there a demilitarized zone between IT and OT networks with protocol-aware firewalls? This DMZ should inspect traffic crossing the IT/OT boundary while preventing unauthorized access in either direction.
    • Access controls: Are connections from corporate IT to production systems authenticated and logged? Maintenance technicians should access production equipment through controlled jump servers, not direct RDP connections.

    Dimension 3: Backup and Recovery Readiness (20 points)

    Backup readiness assesses your ability to recover from data loss, ransomware, or catastrophic equipment failure:

    • Backup scope: Are all critical systems backed up—including ERP databases, CNC programs, PLC configurations, and quality inspection data? Many manufacturers back up office systems but neglect production-critical data.
    • Recovery testing: Do you test backup restoration regularly? A backup that has never been tested is not a backup—it is a hope. Core12 recommends quarterly restoration testing for production-critical systems.
    • Recovery time objectives: Can you articulate how long recovery would take for each critical system? If your ERP goes down, do you know whether recovery takes 30 minutes or 30 hours?

    Dimension 4: IoT and Sensor Security (20 points)

    IoT security evaluates the protection of connected sensors, environmental monitors, and smart devices:

    • Device inventory: Do you know how many IoT devices are on your network? Many manufacturers discover dozens of unmanaged sensors, cameras, and environmental monitors during security assessments.
    • Network isolation: Are IoT devices on dedicated VLANs with restricted communication paths? A compromised temperature sensor should not be able to reach your ERP database.
    • Firmware management: Are IoT device firmware versions tracked and updated? Unpatched IoT devices are among the most common entry points for lateral network attacks.

    Dimension 5: JIT System Uptime (20 points)

    JIT uptime evaluates the availability and reliability of systems supporting Just-in-Time production:

    • ERP availability: What is your ERP system uptime over the past 12 months? For JIT manufacturers, even 99.9% uptime means 8.7 hours of annual downtime—potentially catastrophic during peak production.
    • EDI reliability: Do your electronic data interchange systems process transactions without manual intervention? EDI failures create order processing delays that cascade through the supply chain.
    • Real-time monitoring: Do you have 24/7 monitoring with automated alerting for production-critical systems? Discovering a system failure Monday morning that occurred Friday night means 48+ hours of lost production data.

    Interpreting Your Score

    A (90-100): Your manufacturing IT infrastructure demonstrates enterprise-grade resilience, security, and monitoring. You are well-positioned for compliance audits and supply chain partner requirements.

    B (75-89): Strong foundation with targeted improvement opportunities. Common "B" gaps include incomplete IoT inventories or infrequent backup testing.

    C (60-74): Basic operational capability with significant security gaps. Most "C" organizations have flat networks, limited monitoring, and untested backup procedures.

    D (40-59): Serious infrastructure deficiencies that create production risk. Immediate attention required for network segmentation and backup implementation.

    F (Below 40): Critical infrastructure gaps that likely violate compliance requirements and create unacceptable production risk.

    From Score to Action

    Your Health Score is a diagnostic tool—identifying where you stand today. The next step is translating that score into a prioritized improvement plan that addresses the highest-risk gaps first.

    Core12 offers a complimentary IT Health Review for manufacturers who complete this assessment. During this session, we analyze your score across all five dimensions and create a 90-day improvement roadmap tailored to your production environment.
