Lominger has a large number of leadership and organizational assessment instruments that have been developed over the past 15 years. These assessments come in the form of paper-and-pencil questionnaires, on-line or electronic surveys, and sort cards. These psychological instruments measure such varied constructs as learning agility, team effectiveness, strategic effectiveness, and employee engagement. All these instruments were developed based on empirical data and the experience base of Robert W. Eichinger, Michael M. Lombardo, David Ulrich, and others. It is important that one understands that the scientific literature supports the psychometric integrity and usefulness of the instruments.
