About Gidoka

Gidoka is a free library of guides to kaizen and continuous improvement. We explain the core ideas (PDCA, going to see, root-cause thinking), walk through practical lean tools for small teams, and show how small, steady improvements work in everyday life. There are currently 18 articles across 3 topics, plus a glossary of 54 terms.

Gidoka is published by Digital Nebraska, a company that builds websites and digital tools for local and Midwest businesses.

How we write our articles

• Facts — definitions, dates, versions, platform rules and who created which framework — are checked against primary or authoritative sources such as the Lean Enterprise Institute, The W. Edwards Deming Institute, Toyota's own publications, NIST's Manufacturing Extension Partnership, AHRQ and peer-reviewed research. They’re listed and linked at the end of each article.
• Each article shows the date it was last reviewed, and we revisit articles as guidance changes.
• We don’t invent people, quotes, statistics or case studies. Examples are clearly labeled as hypothetical, and we don’t accept payment to mention a product or company.

Corrections

If something in an article is wrong or out of date, please tell us. We’ll check it against the source and update the article and its review date.
