Are there any obstacles for interventions?

The most difficult task is to help create a safe climate for learning and change. Learning is a lifetime activity. As a human moves up the ladder in the process of learning, he has to go across new dilemmas and problems at every step. Also, learning being a psychological activity can stop abruptly posing a threat to the process. Experimenting new ways are considered as risky because it violates the traditional norms. Hierarchical authority, span of control, and other characteristics of formal systems also daunt experimentation.
