About 8D.wiki

What 8D.wiki Is

8D.wiki is an independent knowledge base and report tool for the 8D (Eight Disciplines) problem-solving method. It is written for quality engineers, supplier-quality engineers (SQE) and manufacturing engineers who have to answer a customer complaint or survive an IATF 16949 audit — not for people collecting definitions.

Operator. 8D.wiki is an independent publication. The site, its wiki and its report tool are run by the founder directly; there is no agency, content farm or outsourced editorial team behind it.

Who Runs It

Founder — Alvin Jin. Alvin spent 20 years inside leading global Tier-1 automotive component suppliers, including as Development Manager of a powertrain division, building and deploying development (R&D) management systems and quality management systems: APQP project flows, design and process FMEA, DRBFM reviews for engineering changes, PPAP submissions, control plans, measurement-system analysis, and the corrective-action / 8D process used to answer OEM complaints and supplier claims.

Credentials

• IATF 16949 expert
• Certified Product Engineering (PE) coach
• DRBFM expert — Design Review Based on Failure Mode
• Development Manager, powertrain division, Tier-1 automotive supplier

His role on the site is editorial rather than authorial: he does not write the articles — he sets the technical bar, reviews and edits every page before publication, and does the formatting. That background shapes what this site covers. Every methodology page here describes the version of the method that has to hold up when a customer auditor asks for the evidence behind D4, or when a supplier's 8D has to be challenged because it stops at "operator error". Where the textbook and the shop floor disagree, the site documents the shop floor and says why. The DRBFM background is why this site treats "the design changed and nobody re-reviewed how it could fail" as a first-class failure mode rather than a side note.

Why the Site Exists

Most 8D reports fail for the same three reasons: the problem description has no data, the root cause never reaches the management system, and the corrective action is never verified. Answering that is a content problem before it is a software problem. So the wiki is the core of the site — 87 in-depth articles across five languages, with real failure cases, worked 5-Why chains, FMEA/PPAP integration, and free templates.

The AI report workspace sits on top of that corpus to remove the formatting work, not to replace the engineering judgement.

How Content Is Produced

• Articles are produced by the 8D.wiki editorial desk: drafted with AI assistance, then reviewed, edited and formatted by the founder against the primary references named in each article (IATF 16949:2016, AIAG core tools, ISO 9001:2015, VDA where applicable).
• AI is used as a drafting and translation assistant only. Every published page is reviewed by a human before release, and translated pages are checked against the English source for numbers, tables and terminology.
• We do not attribute a page to an individual who did not write it, and we do not carry bylines for guest authors who have not done the work they describe.
• Corrections are welcome and are acted on: email [email protected] with the page URL.
• The full policy — sourcing, review cadence, AI disclosure, corrections and advertising independence — is on our editorial policy page.
• Some Chinese-language articles (the product-development-system and engineering-thinking series) were first published on the WeChat column 弧光星云; those pages carry that byline and a source note, and their translations keep the same attribution.

How the Site Is Funded

The wiki, the glossary and the free 8D Excel template are free and require no account. The AI report workspace is a paid subscription. Display advertising is served by Google AdSense.

Advertisers have no influence on content: no sponsored articles, no paid placements inside the wiki, no advertiser review of any page, and no ads inside a generated 8D report body.

Independence and Trademarks

8D.wiki is not affiliated with, endorsed by or sponsored by AIAG, IATF, any vehicle manufacturer or any certification body. IATF 16949, AIAG, VDA, APQP, PPAP, FMEA, MSA, SPC and related names are the property of their respective owners and are used here only to describe the standards the site writes about.
