خلاصه	Goal Attainment Scaling (GAS) is a method for measuring the outcomes of an individualized intervention by writing, in advance, a small set of client-specific goals and defining for each a graded scale of possible outcomes from much worse than expected to much better than expected. After the intervention, the actual outcome on each goal is scored on this scale and the scores are combined into a single standardized index, allowing idiosyncratic, personally meaningful goals to be aggregated and compared across clients and programs. It was introduced by Thomas Kiresuk and Robert Sherman in 1968 to evaluate community mental health programs.	In task-centered social work, task analysis is the qualitative procedure of breaking a client's agreed-upon goal into a sequence of concrete, accomplishable tasks, then examining what helps and hinders the completion of each. Rooted in William Reid and Laura Epstein's task-centered model, it turns a large or vague problem into a chain of small, reviewable actions for the client and worker, and treats the success or failure of each task as data for refining the plan. It is both a planning device and an analytic lens on the change process.
