The 70-20-10 rule for leadership development

The Center for Creative Leadership has a fascinating new article on how to be an effective leader -- spend 70% of your time on challenging assignments, 20% on developing relationships, and 10% on coursework and training.  In these days of flattened and downsized organizations, all three components are difficult.  Which is your organization doing well?  Where do you need improvement?

The other interesting point in the article is the five universal sources of leadership development across cultures:  (1) bosses and superiors, (2) turnarounds, (3) increases in job scope, (4) horizontal moves, and (5) new initiatives.  Which have been important in your career?  Which can you provide to your subordinates? 

In my own career I learned most from increases in job scope and horizontal moves.  But when I was fortunate enough to have a good boss, I learned most quickly from my boss.
