The Individual Leadership Self-Assessment instrument (ILSA) is a 360° process designed to provide insightful, critical friends feedback in a variety of leadership settings to serve as a vehicle for a leader's self-development. A major difference between this and other 360° leadership assessment approaches is the addition of measures of dispositions - the core human elements that are the first things we remember about the best leaders with whom we have worked and those same elements that allow top leaders to be more effective in building positive and productive working climates and relationships.
