This document presents information on organizational effectiveness from a presentation given by Anindita Das. It defines an organization as a social group that distributes tasks for a collective goal. Effectiveness refers to achieving intended outcomes and solving problems. There are four approaches to assessing effectiveness: goal attainment based on objectives; systems approach treating an organization as an open system; internal process focusing on internal health; and strategic constituencies fulfilling demands of supporting groups. Factors like leadership, culture, and resources affect effectiveness. Strategies to improve effectiveness include role clarity, accountability, development, and feedback.
