How Do You Measure Leadership?
I've had 80 bosses. 77 of them sucked. I would march through hell to help the other 3 get something done. For me that pretty much sums it up. All the rest is fluff.FWIW, OP's 3 metrics:  1. Clarity of Thought and Communication
  2. Judgment about People
  3. Personal Integrity and Commitment

Those should be necessary but not sufficient characteristics of every person in your organization.EDIT, response to walterbell & el_benharneen about what made the 3 different (in no particular order):  - They always told the truth (to everybody).
  - They knew their stuff (tech, system, user domain).
  - They figured out the right thing to do.
  - They communicated often and flawlessly.
  - They did whatever it took to get the right thing done.
  - They smiled almost all the time.
  - They made each other person feel special.
  - They made work fun.
  - They were always teaching something.
  - They called bullshit instantly.
  - They protected their team.
  - They inspired us by showing how good things could be.
