สรุป	A single-system design is a time-series approach to evaluating practice in which a single client system — an individual, family, group, or organization — is measured repeatedly on a clearly defined target before and during (and sometimes after) an intervention. By tracking the same system over time rather than comparing a treatment group to a control group, it lets a practitioner judge whether their own intervention is associated with change in the people they actually serve. It is the methodological backbone of the 'accountable professional' tradition codified by Bloom, Fischer, and Orme.	Strengths assessment is a structured way of assessing a client that deliberately foregrounds capabilities, resources, and aspirations rather than deficits and problems. Grounded in the strengths perspective articulated by Dennis Saleebey and operationalized in Charles Rapp and Richard Goscha's strengths model, it surveys the client's life domains — such as daily living, health, finances, relationships, leisure, and spirituality — to record what is already working, what the person wants, and the personal and environmental resources available to get there. Those strengths then become the raw material for goal-setting and intervention.	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.
