What is a definite piece of work assigned to a person known as?

The term that best describes a definite piece of work assigned to a person is referred to as a task. A task typically involves a specific duty or responsibility that can be clearly defined and is often smaller in scope than a project. It is something that a person is expected to complete, contributing to a larger goal or project.

In contrast, a job generally encompasses a broader set of responsibilities and may include multiple tasks as part of an overall role within an organization. A project involves a collective endeavor that has distinct objectives, a defined beginning and end, and can consist of several tasks that require coordination and collaboration. A duty suggests a moral or legal obligation but does not necessarily denote a structured piece of work in the context of business operations.

Understanding these distinctions helps highlight why "task" is the most accurate term for a defined piece of work assigned to an individual.
