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.)
