The purpose of this paper is to systematically review the academic literature on organizational effectiveness (OE) through an analysis of 134 contributions. While OE is the most important goal for an organization, research views on this construct are diversified. Over time, the literature has increasingly focused on antecedents, measures, and more diversified approaches to OE. This paper contributes to the OE literature by developing an integrated conceptual model that considers the levels of antecedents (individual, group, and organizational) as well as measures of OE (financial, operational, structural, and attitudinal). Previous research has focused primarily on organizational-level antecedents and non-financial measures of OE. The paper also discusses the barriers hampering the measurement of OE. An agenda for future research is also provided.
