What term describes a group assigned a specific job to be completed within a certain timeframe?

The term that best describes a group assigned a specific job to be completed within a certain timeframe is a task force meeting. A task force is typically formed to address a particular issue or project that requires focused effort and is composed of individuals who have the skills and expertise needed to complete the task at hand. The members of a task force are usually given a clear mandate and deadline, which distinguishes it from other group settings where discussions may be more general or ongoing.

In contrast, a team meeting often involves regular check-ins and discussions among existing team members about various ongoing projects rather than a specific, time-limited task. A committee gathering usually implies a more permanent group that oversees a specific area or function, possibly involving more generalized discussions and processes rather than a targeted action. Project discussion typically centers around reviewing progress or brainstorming ideas rather than being focused entirely on the execution of a specific task within a set timeframe.
