Most leadership assessment stops at performance and potential. Z-Axis: The Missing Link in Leadership introduces a third dimension: personhood. Recognizing the roles of identity, integrity, and personal flourishing in leadership, this fresh framework moves beyond skill and capacity to embrace the whole person. The Z-Axis integrates competence, capacity, and character for lasting impact by strengthening motivation, enhancing culture, and securing the future. Executives, HR professionals, and organizational leaders will discover how to develop resilient, authentic leaders who not only deliver results but also inspire flourishing in their teams and organizations. This is an invitation to move past managing performance to forming leaders who leave a legacy of success and significance.
