A social organizational theory is outlined, and how types of data drawn from it may be useful in an evaluation context is indicated. Anthropological ethnography is proposed as a more powerful tool in those evaluations undertaken from a phenomenological perspective. Naturalistic/qualitative evaluation lacks a theoretical perspective on how groups of persons order their social lives. The constitutive ethnographic theory of social organization is explained. This theory is presented to provide a link between the phenomenological perspective and the field method of anthropological ethnography. Ethnographic evaluation inquiry allocates resources such that ethnographic observation takes precedence over interviewing. Interviews are primarily used as guides to observation. Constitutive ethnographers believe that group members display their sociocultural standards in interaction. They seek patterns of co-occurrence among phenomena. The program's definition and boundaries are studied as problematic. Inquiry is centered on interactional events. (DWH)
