Here are responses from people on various groups on linkedin which contributed thier thoughts about Qualities of the lean manager. I thought it would be great idea to have it all on one page for  readers benefit.

Jacob Zapolnik • Great outline of the first 8 Qualities of a Lean Manager. I would also add:

-Is always on the look out for learning opportunities
-Will involve the key stakeholders in discussing/creating change
-Acts as a teacher to cascade knowledge of lean methodologies

Tim Jones PMP • “An important one is to train and lead others to practice lean. To give credit to others and to encourage others in the practice of lean.”

Richard Starie • Don’t lay people off after you start to collect data. They will not participate if you do!

Sukri Karim • Lean Manager need to be pushy but respectful..being a change agent is not easy.

Kevin Yamada • A Lean Manager:
- Is continually learning about new and different approaches.
- Leads by example and is a teacher/coach.
- Is data driven.
- Sees the big picture and deals well with the details.
- Should work him/herself out of a job.

Raj •Lean manager shall have the qualities of Systems-Thinking
