Critical infrastructure guide
Critical Supplier Mapping
Identify which external organizations are essential to infrastructure continuity.
Systems note: infrastructure classifications, standards and responsibilities vary by country and operator. Use current local requirements for real decisions.
Why this matters
Identify which external organizations are essential to infrastructure continuity.
Core system ideas
Supplier criticality depends on consequence and replaceability, not spend alone.
Second-tier dependencies can matter when several direct suppliers rely on the same upstream source.
Supplier mapping should include logistics and digital services as well as physical materials.
What to review
Useful reviews usually combine service criticality, dependencies, condition, capacity, maintenance, alternate arrangements, restoration time and clear ownership rather than relying on one isolated metric.
