Abstract: | Summary The provision of a social work service depends significantlyupon assessment of the social situation of clients as determinedby social workers. It is argued that the social worker's understandingof the social situation is framed within a particular way ofthinking about cause and effect. Three different models of suchthinking are used in practice. They are identified as the linearmodel, systems analysis and the management model. The originsand attributes of each model are described and related to thesocial, economic and political environments which have influencedtheir separate developments. The value base underlying eachmodel is explored. Issues relating to the present position ofsocial work are clarified. |
