Few have fully examined what is needed to develop and lead teams in environments where staffing shortages and limited funds are the norm. Traditional management theory no longer holds, as trust is not easily nurtured in environments shaped by scarcity. This book examines what is meant by Complex Adaptive Systems. It accepts that humans are illogical and emotional beings. It offers a trans-disciplinary approach to leadership with elements of neurobiology, systems engineering, complexity science, and philosophy, as well as evolutionary and social psychology. It is a reference for systems engineers and organizational managers, coaches, and psychologists.
