Obsolescence Risk Score for Every Component on Your BOM

One number distills lifecycle stage, production volume trend, distributor inventory trajectory, and manufacturer support into a priority you can act on before a part goes end-of-life.

Überblick

The Obsolescence Risk Score reads the signals that precede a component discontinuation and combines them into a single graded number for every part on your BOM. It weighs lifecycle stage, years since introduction, production volume trend, distributor inventory trajectory, and manufacturer support, then bands the result so you triage by exposure instead of guessing. Roughly 30% of discontinuations ship with no PCN, so a score that moves on early signals catches the parts a notice would have missed. Sort your whole BOM by score and work the riskiest parts first.

Know which parts go obsolete first

A composite of five live signals

The score is not a single data point relabeled as risk. It blends lifecycle stage, years since introduction, production volume trend, distributor inventory trajectory across 10,000+ distributor sources, and manufacturer support posture into one weighted number. Because it reads several leading indicators at once, a part can climb into the danger zone on falling distributor stock and a flattening production trend long before its lifecycle status officially changes to NRND or last-time-buy.

Production volume trend Declining

Manufacturer support Limited

Color-coded bands for fast triage

Every score lands in a Low, Medium, High, or Critical band, so a 2,000-line BOM resolves into a short list of parts that actually need attention. You sort and filter your bill of materials by band, route Critical parts to a sourcing or design review, and leave the green-banded majority alone. The bands turn an abstract number into a clear next action for your engineering and sourcing teams.

Scores that move with the signals

The score updates as the underlying signals change, not on a static annual refresh, so a part that was healthy last quarter reflects this quarter's inventory drawdown and production cuts. Z2 back-tests the model against actual time-to-end-of-life, so the correlation between a high score and a real discontinuation is validated rather than asserted. You watch a part's score trend over time and act while a last-time-buy is still on the table.

Part of Part Risk Manager

The Obsolescence Risk Score is one capability inside Part Risk Manager, Z2's component risk platform covering 1B+ parts. It draws on the same data layer that powers lifecycle forecasting, compliance screening, and supplier risk, so a high-scoring part is already mapped to its lifecycle forecast, its crosses, and the sites that consume it. Because every signal lives in one record, a single risky part becomes an end-to-end view from score to replacement to affected assembly.

Häufige Fragen

What goes into the Obsolescence Risk Score?

It combines lifecycle stage, years since introduction, production volume trend, distributor inventory trajectory, and manufacturer support into one weighted number, so it reflects several leading indicators rather than lifecycle status alone.

How often does the score update?

The score recalculates as its underlying signals change rather than on a fixed annual schedule, so it reflects this quarter's inventory and production movements instead of last year's snapshot.

Is the score actually predictive of end-of-life?

Z2 back-tests the model against real time-to-end-of-life, so the link between a high score and an actual discontinuation is validated against history, not just asserted. Roughly 30% of discontinuations carry no PCN, which is why an early-signal score matters.
