The global marketplace, with its complexity, immediacy, and ubiquitous disruptions places almost impossible demands on its leaders and its leadership ranks. For many years, a top, perennial contender for the "what keeps CEOs up at night" list has been a severe lack in both the quantity and quality of effective leaders. The war for talent has been figuratively bloody and literally protracted. Leadership development and coaching modalities abound, but demand appears to be much greater than the supply of effective and measurable solutions. Nowhere does there appear to be a scalable approach to accelerate into this demand curve. This descriptive phenomenological inquiry explores the lived experiences of 16 leaders who participated in an experimental Facilitated Peer-group Coaching experience (FPC). FPC is a coaching methodology where participants work on both their own leadership development and the development of their peers. Participants learn to coach and develop each other with the assistance of a trained facilitator. Subjects in this study responded to 20 face-to-face interview questions designed to identify their thoughts, perceptions, feelings and perspectives. The findings and conclusions of this study revealed five developmental fields that catalyze and empower leadership growth. These fields include creating community, self-exploration and illumination, the community mirror, leadership development, and organizational business results. Those fields comprise an ecosystem that presents opportunities for global organizations, coaches and coaching organizations, and academic scholarship.
