The correct answer is a procedure document because it specifically outlines the step-by-step instructions necessary to complete a task or achieve a particular result. Procedure documents are designed to ensure consistency and efficiency in performing tasks, detailing exactly how processes should be carried out.

Therefore, for achieving a desired outcome through precise actions, a procedure document is the most appropriate choice.
