Developing Leadership Ability 70-20-10

According to the Center for Creative Leadership there is a model for learning and development that blends experience, relationships and training.  Referred to as the 70-20-10 model, approximately:

• 70% of learning is provided through the use of challenging assignments and on-the-job experiences.
•  20% of learning is developed through relationships, networks, and feedback.
•  10% of the learning is delivered via formal training processes.  

Does your organization put most of its leadership development resources into training?  Sometimes its easier to purchase external vendor training rather than develop the internal infrastructure to support succession planning with stretch/rotational assignments, coaching, mentoring, and action learning.  The weaker this internal support infrastructure, the more important the formal training will be, but it can't be a close substitute for the lessons learned on the job and
through feedback from peers, bosses and mentors.
