Industrial Control Systems (ICS) — System Fragility Self-Assessment Guide

ICS System Fragility Self-Assessment Guide

Industrial systems usually do not become fragile all at once. Fragility builds quietly through untested design assumptions, incomplete commissioning characterization, disconnected changes, aging assets, and gaps in operational knowledge.

The ICS System Fragility Self-Assessment Guide helps engineers, technicians, managers, and operations teams review where those risks may be accumulating before they show up as failures, downtime, nuisance alarms, or hard-to-explain behaviour.

This tool is designed for structured review, team discussion, project handover preparation, and early risk identification in industrial control system environments.

What’s included:

• A printable Word document version for review sessions, workshops, and sharing
• An Excel spreadsheet version with status fields and summary tracking
• Diagnostic questions across major sources of integration risk
• A simple rating structure to identify what is known, partially addressed, unknown, or not applicable
• A summary-style view to help see where fragility is concentrated

Use this guide to review:

• Design-phase assumptions
• Commissioning and characterization gaps
• Change management structure
• Asset lifecycle and vendor support
• OT cybersecurity posture
• Documentation and institutional knowledge

This is not a pass/fail audit or a prescriptive engineering procedure. It is a practical thinking tool for helping teams see where uncertainty, assumptions, and hidden dependencies may be building inside an industrial control system.

Best for: engineers, controls teams, maintenance leaders, OT professionals, facility managers, and anyone responsible for understanding the health and resilience of an existing ICS environment.
