GM is commonly used to stand for General Manager in business settings. The best way to express this is General Manager (GM) because it gives both the full term and its acronym at once, removing any ambiguity about what GM refers to. Other possibilities like Gas Model or Global Manager aren’t standard expansions for GM in this context, and simply saying General Manager doesn’t explicitly define the acronym. In typical documents, you introduce the term with its abbreviation in parentheses so readers know what GM means when it appears later.
