Senge lays out five disciplines that are essential for organizations to become learning organizations: personal mastery, mental models, shared vision, team learning, and systems thinking. These disciplines are interrelated and reinforce each other. Personal mastery involves continually learning and improving oneself. Mental models involve understanding one's own assumptions and views. Shared vision involves developing a common purpose that people can connect with and commit to. Team learning involves aligning the capabilities of a team through open communication and sharing of knowledge. Systems thinking underlies the other disciplines and involves seeing interrelationships and patterns of change rather than isolated events. Mastering these disciplines can help organizations continually learn and adapt.
