Which term refers to a company task that is assigned to an external entity?

The correct term that refers to a company task assigned to an external entity is "Outsource." Outsourcing involves delegating specific business functions or processes to a third-party provider. This is often done to reduce costs, improve efficiency, or allow a company to focus on its core competencies by leveraging the expertise and resources of other organizations.

In contrast, delegation typically refers to assigning tasks or responsibilities within the same organization, often from a manager to a subordinate. Internal transfer involves moving an employee or task from one department or location within the organization to another, without involving any external parties. Operational shift signifies a change in the methods of operation within a company and does not specifically pertain to the aspect of outsourcing tasks.

Thus, "Outsource" clearly captures the essence of engaging an external entity to handle specific tasks, making it the correct answer.
