Measurement of the organizational effectiveness of the Cooperative Extension Service (CES) could be enhanced by utilizing a multidimensional perspective in measuring outcomes of various organizational activities, particularly the Extension educational system of program development. Because multiple and conflicting environmental constraints, goals, constituents, and time frames can influence effective performance (inputs), individual performance (outputs), and changes in behavior of constituents (program accomplishments), factors within and beyond the control of CES must be included. The strength of the CES educational system is in its involvement of people in the program development process of determining planning and carrying out programs that meet their needs. Because of the importance of individual performance in carrying out system activities, organizational effectiveness is linked to measures of individual performance. Five procedural requirements are necessary to provide accurate and relevant results: needs assessment; job analysis of critical incidents necessary for effective performance; multivariant measurement and analyses to assess accuracy and relevance of measures used to determine individual performance and program accomplishments as they relate to organizational effectiveness; recognition of factors beyond organizational control and the range of options open to organizations; and commitment of adequate resources and administrative support to the task.
