This page covers how I handle conflicts of interest, affiliate relationships, and sponsorships on Six Sigma Study Guide.
Editorial Independence
No company or individual can pay me to publish favorable content, change a recommendation, or remove accurate information. If I recommend a book, a tool, or a certification body on this site, it’s because I think it serves the reader, not because of a payment arrangement.
Affiliate Links
Some pages on this site contain affiliate links, mainly to books and study resources I’ve personally found useful. If you click one of these links and make a purchase, I may earn a small commission at no extra cost to you. This never affects which products I recommend. I only link to things I’d recommend with or without the commission.
Sponsorships and Partnerships
From time to time, I work with partners in the Six Sigma and process-improvement space. Any sponsored content or paid partnership is clearly labeled as such on the page where it appears. I turn down partnerships that would require me to misrepresent a product or withhold a fair comparison.
Accuracy Standard
I try hard to get the technical material on this site right, formulas, definitions, body-of-knowledge coverage, and exam content. When I’m not fully certain about something, I say so rather than guess with false confidence. If you spot something that looks wrong, see the Corrections Policy for how to report it.
