What is a defined way of accomplishing a task or objective in business called?

The term that best describes a defined way of accomplishing a task or objective in business is "method." In business contexts, a method refers to a specific technique or procedure that outlines how tasks should be carried out to achieve desired outcomes. It provides a systematic way to ensure that actions are taken consistently and effectively, often including steps or guidelines that must be followed.

While "procedure" and "approach" are related concepts, they have slightly different implications. A procedure typically refers to a detailed series of actions or steps designed to accomplish a specific task, often emphasizing the order and format of those actions. "Strategy," on the other hand, refers to a broader plan of action designed to achieve long-term goals and outcomes rather than the specific tasks themselves.

Thus, "method" accurately encompasses the idea of a defined and systematic approach to accomplishing tasks within a business framework, making it the most suitable choice.
