The Enneagram is a more complex personality model. As a typology, it defines nine interconnected personality types. The historical evolution of the Enneagram is still disputed and its limited psychometric analysis is not entirely accepted among relevant academic studies. Nevertheless it found its place not just among spiritual processes but also as a tool for Business Coaching or Team Coaching. Especially in the work place the Enneagram supports the understanding of interpersonal dynamics within a team and leads to personal growth through strengthened self-awareness.
