The Most Revealing Inner-Core Assessment
The Mattone Leadership Enneagram Inventory (MLEI)® is one of the most revealing “inner-core” leadership assessments that exist in the marketplace today. It is the strength, vibrancy and maturity of a leader's character, self-concept, values, thinking patterns and emotional make-up (inner-core) that determines their success in the “outer-core” (skills and competencies). In other words, success as a leader starts with greatness in the “inner-core”.
