TreQna.com, our open source quality improvement methods global learning community, has been open 10 years as of 2015.

Our partners at TreQna University are celebrating with a sale on all LSS Training materials, which are now priced at only $15 per each module.

star Sale must end December 31, 2015.


TreQna was established early 2005 and started life as an open source venue for Six Sigma. The policy was, and still is, that everything on TreQna is free. Over time, TreQna has expanded to encompass other business/process improvement methodologies such as Lean, TPM, PDCA.

We have an alliance with TreQna University where you can find several business/process improvement training courses. (Some are free, certificated and highly acclaimed.)

Please feel free to browse and become involved with our forum. We have a lot of members who are knowledgeable, willing to answer your questions and interact with you. Besides that, we offer newsletters, articles and other downloads. If you would like to contribute, please let us know.

We're a friendly community and more than willing to help out, no matter what the problem or issue.

Remember: "sharing knowledge = gaining knowledge = interaction!"

If you have a question which you don't want to post in public (for any reason) please feel free to contact any of our volunteers:

We look forward to your active posting and involvement.
