What outcomes do quality control & inspection deployments report?

Medians computed from 30 of 123 deployments whose reported figures could be parsed into comparable units. Values are as reported by the original source, not independently audited.

How these numbers are computed

  • Population: every published quality control & inspection case study in our manufacturing corpus (123 deployments), recomputed from the database — no figure on this page is hardcoded.
  • Outcome medians: computed only within like-for-like buckets, and only where a reported value parses into a comparable unit. 30 of 123 deployments contributed; the rest report figures in units we cannot compare, and are excluded rather than coerced.
  • Source figures are as reported by vendors, public filings, and verified submissions. They are not independently audited, and vendor-reported outcomes skew optimistic — treat medians as the shape of what gets claimed, not a guarantee.
