What is BRB in business?

Excuse me, could you kindly elaborate on the acronym "BRB" in the context of business? I've encountered this term in several discussions but haven't been able to pinpoint its precise meaning. Is it a specific business strategy, a technical jargon within a particular industry, or perhaps a reference to a new trend or concept? Clarifying its usage and significance would greatly assist me in understanding its relevance in today's business landscape. Thank you for your assistance in this matter.
