"...20% of development is through formal training and 80% is through informal learning. We learn by doing and by sharing."
This is an interesting application of the 80/20 rule. I've heard many versions of this in terms of 20% of a the people doing 80% of the work, or 80% of sales comes from 20% of the sales force. And I guess that I can agree with this analogy because I went to school for 10 years to earn my professional degree and I worked in my field for 15 years where I learned quite a lot. Whether I can say it's more than what I learned in school is debatable, but I guess I haven't practiced long enough. I will say that in the classroom, 80% of my satisfaction, headaches, problems, or joy, usually comes from 20% of the students in any particular class.
