Scholars studying organizational communication tend to feel that all organizational problems are rooted in communication, but it is difficult to diagnose the particular problems of an organization without an explicit model of what constitutes a healthy organization. Organizational effectiveness is goal-related, multidimensional, perceived differently by individuals, and time-dependent. Organizational effectiveness is the extent to which an organization is meeting its goals, whatever they may be. A four-part model of organizational communication analysis shows how communication is interrelated with many other factors influencing effectiveness, suggesting that communication strategies should be developed around these factors rather than being predetermined and packaged. The advantages of this model are that it is tailored to individual companies, it considers constraints that may inhibit goal achievement, it emphasizes the link between communication and end products of an organization, and it recognizes the cyclical nature and temporality of communication programs. The major implication in this model is the need for research that specifies the organizational outcomes of effective communication. (HTH)
