I recall taking the Strengths Finder 1.0 version test while I was in NASA's leadership development program.  I did find that it provided a common language around which to share and have conversations of individual strengths.  For me, the Strengths Finder was a paradigm shift - utilizing and further improving one's strengths provides a greater return on investment than working on one's weaknesses!  This is a fascinating perspective I'm still exploring. I welcome your comments and reactions to that.  Cheers!
