Rick Maurer wrote a great post Change Management and Anxiety at Change Management News. I recently came across his site and find it to be informative, concise, and highly relevant. I have added his blog to my links on this site.
Cornelius Fichtner, PMP is a mentor to me for Project Management via his PM Podcast and his PMP Prepcast. He recently attended a Lean Six Sigma workshop and shared his initial impression on the podcast Episode 093: Lean Six Sigma Overview. It was really fun to hear his first thoughts and I am excited more project managers will get exposure to Lean because of him!
