“In what is known as the 70/20/10 learning concept, Robert Eichinger and Michael Lombardo, in collaboration with Morgan McCall of the Center for Creative Leadership, explain that 70 percent of learning and development takes place from real-life and on-the-job experiences, tasks, and problem solving; 20 percent of the time development comes from other people through informal or formal feedback, mentoring, or coaching; and 10 percent of learning and development comes from formal training.”
