What is the core acronym in business?

Can you clarify what you mean by the "core acronym in business"? Are you referring to a widely recognized term or abbreviation that is central to the operations and functioning of a business? If so, there are several potential answers depending on the context. For example, in accounting, "ROI" (Return on Investment) could be considered a CORE acronym that measures the profitability of an investment. In marketing, "KPI" (Key Performance Indicators) might be seen as a central acronym for tracking progress towards goals. Could you provide more context or specify which area of business you're interested in, so I can give a more precise answer?
