How do you calculate a network resilience score?

Multiply the three ratings: severity x occurrence x detection. With severity 6, occurrence 4, and detection 3, the raw product is 72; this tool returns a normalized risk score of 4.55 on its scale.

What is a good network resilience score?

Lower is better because the score measures risk, not strength. Rank all your network nodes and treat the top tier — the highest-scoring failure modes — as your mitigation priorities regardless of the absolute number.

What do severity, occurrence, and detection mean here?

Severity is the impact if the node fails, occurrence is how likely the disruption is, and detection is how hard it is to see coming. A high detection score means you would get little warning, which raises overall risk.

Is this the same as an FMEA RPN?

Yes, structurally. It applies the classic risk priority number logic to supply network nodes instead of part defects, so the same triage rules apply: attack high-severity, high-occurrence, low-warning risks first.

Why use the same scale across risks?

Multiplying ratings only produces a comparable ranking if every risk is scored on the identical scale. Mixing a 1-5 scale with a 1-10 scale silently inflates some scores and breaks the ranking.

How do I lower a node's score?

Reduce any factor: cut severity with a backup source, cut occurrence with safety stock or a more stable supplier, or cut detection difficulty with better monitoring and lead-time signals.

Make-Buy, Outsourcing & Network Design calculator

Network Resilience Score Calculator

A network resilience score is a risk priority number for your supply and manufacturing network, built the same way an FMEA RPN is: severity times occurrence times detection. Supply chain risk managers and network designers use it to rank single-source dependencies, port chokepoints, and sole-plant exposures on one comparable scale. It matters because resilience budgets are finite, and ranking risks by a consistent score keeps spending focused on the failure modes that are severe, likely, and hard to see coming. The higher the score, the sooner that node belongs on the mitigation roadmap.

What this calculator does

Estimate network resilience for make-buy, outsourcing and network design using production-ready inputs so teams can rank risks and decide which issue needs containment, controls, or escalation first.
Use it when network resilience in make-buy, outsourcing and network design needs a defensible ranking against other make-buy, outsourcing and network design risks for the next review.
It multiplies severity, occurrence, and detection ratings into a single risk priority score for a network failure mode.

Formula used

Network resilience risk score = network resilience severity score × network resilience occurrence score × network resilience detection score
Use the same scoring scale across comparable network resilience risks.

Inputs explained

Network resilience severity score:
Network resilience occurrence score:
Network resilience detection score:

How to use the result

Use it to triage and rank supply network risks during footprint design, dual-sourcing reviews, or annual continuity planning.
It is ordinal, not absolute — a score of 72 is not twice as risky as 36, and the result is only as good as the consistency of your rating scale.

Current U.S. benchmarks

Sourcing currencies as of 2026-07-02 (Federal Reserve H.10): 6.7886 CNY and 17.4524 MXN per USD. Landed-cost comparisons move with these daily rates.
U.S. iron and steel imports ran $2.1B in May 2026 (Census International Trade). The U.S. ran a trade deficit of $0.4B in the category that month. Import volumes are the pressure gauge behind tariff and reshoring decisions.
