Sole-source count, lifecycle-status mix, lead-time exposure, qualified-alternates ratio, and per-line margin sensitivity — and how we report them at every NPI review.
Public-record signals we monitor — datasheet revisions, distributor stock curves, manufacturer roadmap notes — and the leading indicators they actually produce.
The three-tier inspection regime we apply to grey-market parts: optical, X-ray, and (for high-stakes BOM lines) destructive die inspection.
Where to look beyond the big-two distributors when MLCC allocation tightens, and the dielectric/voltage-derating gotchas in alternate-part substitution.
A rolling snapshot of the families currently on allocation, which alternates are clearing customer qualification, and where we're holding strategic stock.
