Is a strategy adopted by management to maintain or slightly improve the amount of business that an SBU is generating?

Yes, a strategy adopted by management to maintain or slightly improve the amount of business that a Strategic Business Unit (SBU) is generating is often referred to as a "stability strategy" or "maintenance strategy." This approach focuses on sustaining current performance levels, optimizing operations, and making incremental improvements rather than pursuing aggressive growth. It is typically employed in mature markets where significant expansion opportunities are limited.
