The Core5 Model of

Effective Leadership

The Five Factors That Separate Good Leaders from Great Ones

Leadership remains one of the most influential factors in organisational performance, yet global employee engagement continues to lag despite billions invested in leadership development each year. The Core5 Model of Leadership Effectiveness brings together leading research, practical insights, and data from more than 2,000 leaders to identify the five essential competencies that differentiate high-performing leaders from the rest.

Developed by Peter Berry Consultancy, the Core5 Model combines decades of leadership science from Hogan Assessments, Hogan 360, and globally recognised thought leaders including Robert Hogan, Jim Collins, and John Kotter. The paper explores how the most effective leaders build credibility, inspire others, think strategically, maintain emotional intelligence, and sustain achievement focus to create engaged, high-performing teams.
