How do you calculate a Product Lifecycle Recovery Score?

Multiply the recovery impact severity, recovery barrier occurrence, and detection-weakness scores on a common scale. The calculator returns a normalized score — for example severity 7, occurrence 5, and detection 6 produce a recovery score of 6.05 on this model's scale.

What is a good Product Lifecycle Recovery Score?

Lower is better — it means the product is easier to recover at end of life. There's no fixed pass line; use it relatively. Rank all components by score and attack the highest first, the way you'd triage RPNs in a design FMEA.

What's the difference between severity, occurrence, and detection here?

Severity is how damaging a recovery failure is (lost material value or contamination). Occurrence is how often the recovery barrier shows up. Detection-weakness is how poorly your current process catches or controls the problem before product reaches end of life.

How is this different from a standard design FMEA?

Same mathematical structure, but the failure mode is 'failure to recover value at end of life' rather than a functional failure. The severity axis weighs circular-economy impact — material lost to landfill, contamination, or remanufacture infeasibility.

Why use multiplication instead of adding the scores?

Multiplication amplifies risks that are bad on multiple axes — a high-severity, frequent, hard-to-detect barrier scores far above one that's only bad on a single dimension, which is exactly the prioritization you want.

Can a low score still hide a serious recovery problem?

Yes. A high-severity barrier with low occurrence and good detection can score low overall yet still cause catastrophic recovery failure when it does occur. Always review high-severity items separately regardless of total score.

Product Lifecycle Recovery Score Calculator

The Product Lifecycle Recovery Score is an FMEA-style risk priority number applied to circular-economy design: it ranks how badly a product or component resists end-of-life recovery by multiplying severity, occurrence, and detection scores. Design-for-disassembly engineers, sustainability teams, and remanufacturing planners use it to prioritize which recovery barriers to fix first across a portfolio. It matters because circular goals — reuse, remanufacture, recycle — fail quietly at design time: glued joints, mixed materials, and missing material markings each raise recovery risk, and without a consistent score you can't tell which problem to attack. The score gives comparable risk numbers across designs so engineering effort lands where it moves recovery rates most.

What this calculator does

Score recovery risk across a product lifecycle using impact, occurrence, and detection ratings for reuse, repair, or recycling barriers.
a team needs to prioritize redesign, documentation, or take-back controls for a product lifecycle recovery risk
It computes a recovery risk priority number by multiplying a severity score, an occurrence score, and a detection-weakness score on a common scale.

Formula used

Product Lifecycle Recovery Score score = recovery impact severity score × recovery barrier occurrence score × current detection and control weakness score
Use the same scoring scale across comparable circular recovery and design risks.

Inputs explained

Recovery impact severity score:
Recovery barrier occurrence score:
Current detection and control weakness score:

How to use the result

Use it during design reviews or end-of-life audits to rank recovery barriers and prioritize design-for-disassembly fixes.
Like all RPN methods, it can mask a critical high-severity issue behind a low product score, so always review severity in isolation as well.
