'工作组' (gōng zuò zǔ) literally combines 'work' (工作) and 'group' (组), meaning a temporary or task-specific team formed to address a particular issue, project, or mission. It is commonly used in governmental, corporate, educational, and technical contexts — for example, a team dispatched to investigate an incident, implement reforms, or support disaster relief. Unlike permanent departments, a working group usually has a defined scope, timeline, and deliverables.

The term carries a formal, institutional tone and often implies coordination across departments or organizations. While '组' alone can mean any small group, adding '工作' specifies purpose-driven collaboration rather than casual or social grouping. It’s frequently seen in official announcements, meeting minutes, and policy documents — especially when cross-functional expertise is required. The word rarely appears in informal speech or personal contexts.
