Final answer:
A directive with a one-time or brief nature and a self-cancelling provision, with the same force as an instruction, is commonly known as a temporary directive or an interim order.
Step-by-step explanation:
In the context of organizational and legal documents, a directive which possesses a one-time or brief nature and includes a self-cancelling provision, operating with the authority equivalent to an instruction, is typically referred to as a temporary directive or an interim order. Such directives are often issued to address immediate concerns and are designed to expire automatically after a certain event or period without the need for formal withdrawal. They bear the same force and effect as permanent instructions, but they are established with the understanding that they are only valid for a short timeframe or until a specific condition is met.
