Tóm tắt	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.	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.
