How do you calculate a kit component shortage risk score?

Multiply the shortage impact severity, the shortage likelihood, and the detection weakness scores together. The calculator here returns 5.95 for the example, giving a single ranking number per component.

Why multiply the three scores instead of adding them?

Multiplication mirrors FMEA risk priority numbers: a component must be severe, likely, and hard to detect to be truly dangerous, and the product punishes components that are bad on multiple axes far more than a sum would.

What is a good shortage risk score?

It is relative to your scale, but the point is ranking: the highest-scoring components, like sole-sourced cartridges with long lead times, get mitigation first while low-scoring commodity items are accepted as-is.

Should I always use the same scoring scale?

Yes. Using one scale across swabs, tubes, labels, reagents, pouches, and cartridges is what lets you compare them, otherwise the rankings are meaningless across component types.

How do I lower a component's score?

Reduce occurrence with dual sourcing or buffer stock, reduce detection weakness with supplier lead-time alerts and inventory triggers, or reduce severity through design alternatives that allow a substitute component.

Can a low total score still be dangerous?

Yes, that is the main caveat: a component with severity 9 but very low occurrence can score low overall, so always review high single-factor components even when the product is small.

Kit Component Shortage Risk Calculator

Kit Component Shortage Risk is an FMEA-style risk number that ranks how dangerous a stockout of each kit component is by multiplying its impact severity, its likelihood of going short, and how poorly you would detect the shortage before it halts a build. In diagnostic kit assembly a single missing swab, tube, label, reagent, pouch, or cartridge stops the entire kit from shipping, so supply and quality teams use this score to triage which components deserve dual sourcing, larger buffers, or tighter monitoring. It matters because not every component carries equal risk: a custom cartridge with one qualified supplier and a long lead time is a different problem than a commodity label, and a single ranking lets you put scarce mitigation effort where it actually protects the line. Scoring every component on one consistent scale is what makes those comparisons honest.

What this calculator does

Score the risk that a missing or constrained kit component will stop production, delay release, or force partial lots for diagnostic and lab consumable products.
a diagnostics or lab consumables team needs to prioritize dual sourcing, safety stock, component substitutions, or escalation for critical kit materials for a kit component supply review
It multiplies severity, occurrence, and detection scores into a single shortage risk priority number for a kit component.

Formula used

Kit component shortage risk score = shortage impact severity score × component shortage likelihood score × shortage detection weakness score
Use one scoring scale across comparable components so swabs, tubes, labels, reagents, pouches, and cartridges can be ranked consistently.

Inputs explained

Shortage impact severity score:
Component shortage likelihood score:
Shortage detection weakness score:

How to use the result

Use it when triaging which kit components need dual sourcing, buffer stock, or closer supply monitoring.
As a multiplicative score it is sensitive to scale choice and can mask a high single factor, so a severe component with low occurrence can still rank deceptively low.

Current U.S. benchmarks

U.S. manufacturing runs at 75.6% of capacity with new factory orders at $657B per month (Federal Reserve and Census, May 2026).
The U.S. has 8,825 medical equipment and supplies establishments employing about 308,388 workers (Census County Business Patterns, 2023).
