What makes for success at the highest levels of executive leadership? In this volume, research on the skills, knowledge, abilities and other characteristics that define effectiveness of senior executives is examined and integrated in a comprehensive analysis. Industrial psychologists, organizational consultants, and others who work with executive leaders can use this integrated framework to develop ways of assessing, selecting, training, developing and coaching executives based on solid empirical data. Graduate students and other researchers should find research paradigms and recommendations for avoiding common methodological problems that have plagued research on executive leadership in the past.
