This article was posted on 10th September 2009. I think it was the same period where whole quality world started looking at Lean + Six Sigma combination.
I felt this article focused on how industries were looking at quick returns from Six Sigma. This thought was a trigger for combining Lean principles with Six Sigma tools. As mentioned in the article, most of the organizations were looking for benefits within 3 months from the time of project initiation. As six Sigma need to be stabilized data to study and proper implementation of the tools & techniques, it is not always possible to get benefits within 3 months. Though organizations were expecting the quick benefits, they were not ready to move out of the SS for that.
Lean can give quick returns based on VA & NVA analysis in the process, what if Lean and SS works together...?
Organizations can start realizing the benefits within a short frame of time by converting process NVAs and at the same time, they can continue with SS to re-engineer and sustain the benefits for a long time. On the face of it, the article is looking like it is focused on re-entry of SS, but in my view, it is focused on changes in SS.
