worktaken

Worktaken is a term used in several domains to denote the portion of work that has been taken, claimed, or extracted from a larger task, system, or process. It does not have a single canonical definition, but two common senses appear in practice: a physical-thermodynamic sense and a management sense.

In thermodynamics or mechanical engineering, work taken refers to the amount of mechanical work removed from a system by an external agent or device. It is linked to the concept of work output and is subject to sign conventions; depending on the convention, it may be described as energy delivered by the system to its surroundings, or as energy recovered by the agent. The term is less common in formal textbooks but appears in informal discussions of energy transfer and engine performance.

In project management or production planning, work taken indicates how much of the scheduled work has been completed or claimed by a team member. It is often measured in units such as hours or task points. For example, if a task planned for eight hours has three hours completed, the worktaken is three hours. Different tracking systems may use terms like work completed or work performed to describe the same idea, which can cause terminology drift.

In software development and operations, worktaken may refer to tasks that have been picked up or assigned to a person or team, as opposed to those that are still unassigned. Because the term is context-dependent and informal, professionals typically rely on more precise terms such as completed work, in-progress work, or work in queue.
