About
Built by quality professionals, for quality professionals.
RCA Toolkit is a working resource center for the people who actually run investigations, write corrective actions, manage CAPAs, hold suppliers accountable, and survive audits. Everything here comes from real manufacturing experience — not generic textbook theory.
Who this site is for
We build for quality engineers, supplier quality engineers, CAPA owners, manufacturing engineers, quality managers, and operations leaders working in regulated and high-mix manufacturing environments — automotive (IATF 16949), aerospace (AS9100), medical device (ISO 13485 / FDA 21 CFR 820), and general ISO 9001 shops.
What we publish
- Downloadable templates (Word and PDF) for RCA reports, 5 Whys, Fishbone, 8D, NCRs, SCARs, and corrective action plans.
- Practical guides on root cause analysis, corrective action, CAPA, supplier quality, and audits — written the way a senior quality engineer would explain it to a new hire.
- Reference content on common manufacturing defects, audit findings, and the structures auditors actually look for.
Our editorial standard
Every page is reviewed against three questions: Would a working quality engineer use this on Monday morning? Would this hold up in front of a third-party auditor? Does it teach something that isn't already obvious from the standard? If the answer to any of those is no, the page gets rewritten or cut.
We don't publish AI-generated filler, marketing fluff, or vague "best practice" lists. Content is written by people with hands-on experience in supplier quality, corrective action, internal and external auditing, and root cause investigations on the shop floor.
