A hearty welcome to a couple relatively new blogs joining the lean blog community.
Business Lean by Neil Kjeldsen is published by Ultriva, which makes e-kanban software products.
Lean Software Engineering focuses on... lean software engineering. Perhaps perfectly intuitive names are themselves a form of lean? No waste of "figuring out what the heck they're about"... as opposed to "Evolving Excellence"...
Take a couple minutes to check them out! For a nice long list of lean-oriented blogs, see the list on the left column. Let me know if yours isn't listed.
