Note: Importing known-good component data with supply chain fields pre-populated from authoritative distributor and
lifecycle sources at the point of entry eliminates the manual verification step that makes large-scale library cleanup
impractical.
7. Govern the New Part Introduction Process
New part introduction is where supply chain risk most commonly enters the library. A designer identifies a part that meets the
electrical requirements, requests it be added, and if the NPI process does not include supply chain verification before
approval, the library inherits whatever risk that component carries. That risk then propagates into every design where the part
is placed.
NPI governance is not about slowing down part requests. It is about ensuring that verification happens before the part is
committed to a design, not after it has been placed in fifty schematics across multiple programs.
Standard NPI Process
Without a governed NPI process, the typical sequence is: designer identifies a needed component, researches it
independently, creates a part request, the request is reviewed and approved, CAD models are created, and the component is
incorporated into the design. When this process is not optimized, the review and model creation steps introduce delays,
especially when multiple new parts are required simultaneously. The result is designers working around the library with locally
created parts of uncertain quality.
A governed NPI process addresses this by defining clear steps, roles, and timelines so that the library stays ahead of design
needs rather than becoming a bottleneck.
Ideal Verification Before Part Approval
Before a new component is approved and made visible to designers, the librarian/engineer should confirm:
f
Lifecycle status from an authoritative aggregator, not just the manufacturer datasheet
f
Lifecycle risk rating and predicted years to end of life
