From The American Management Association:
I would suspect that some of the Top Leaders are not true business leaders….some are good business thinkers/writers/scholars who have studied the aspects of business leadership.
Jim Collins….Simon Sinek….Ken Blanchard….Seth Godin….John Maxwell are strong thinkers/writers on business/organizations. I can’t disagree with them being on the “Top 30”.
One significant name missing is Tom Peters….if for nothing else….”In Search of Excellence” (Tom Peters/Bob Waterman – 1982) had a dramatic change on managing and leading companies.
