What term refers to an established or official way of doing something?

The correct answer is the term that captures the essence of an established or official way of doing something. In this case, a procedure refers to a set of specific steps or instructions that outline how to perform a task or achieve a certain goal. Procedures are often detailed and provide clear guidance to ensure consistency and compliance in actions. They are implemented to standardize operations within organizations and help in facilitating effective execution of tasks.

While some of the other terms like protocol, policy, and rule may seem related, they serve slightly different purposes. Protocol generally refers to a formal set of guidelines, particularly in diplomatic or technical contexts. A policy can reflect a broader principle or direction for an organization and does not necessarily provide the specific steps required for implementation. A rule is often a specific guideline or regulation that must be followed, but it may not outline the exact procedure to follow for various actions. By focusing on the step-by-step framework, the concept of a procedure is distinctly about providing a clear and established method for accomplishing tasks.
