What is a team of employees from different parts of a company assigned to work together on a specific project called?

The term that describes a team of employees from different parts of a company who are assigned to work together on a specific project is a "Task Force." This designation typically reflects a temporary group established to tackle a specific issue or project, bringing together individuals with various expertise and skills from different departments to collaborate effectively.

While a "Project Team" also refers to a group focused on a particular project, it often encompasses members from the same function or discipline rather than a diverse mix from various sectors of the company. A "Committee" usually has a more permanent or ongoing status within an organization, often tasked with governance or oversight rather than a specific project focus. A "Work Group" can imply a more general assembly of colleagues who may not have the defined roles or urgency that a task force represents.

Understanding these distinctions helps clarify why the term "Task Force" is the most accurate descriptor for that specific scenario in which cross-department collaboration is mobilized for a particular project.
