Which of the following is NOT a focus area for ROI analysis?

In an ROI (Return on Investment) analysis, the primary focus areas typically include cost savings, revenue generation, and time efficiency. These aspects directly relate to measuring the financial benefits obtained from an investment relative to its costs.

Cost savings refers to reductions in expenses that can increase profitability. Revenue generation involves the income produced from investments that contribute to a company's overall financial performance. Time efficiency looks at how investments can lead to quicker processes and improved productivity, which can also impact financial outcomes positively.

Market expansion, while important for strategic growth, does not directly relate to calculating ROI, as it's more about increasing the company's presence or customer base rather than a direct financial return or measurable savings. Therefore, this option does not fit within the typical parameters of a focused ROI analysis, which targets quantifiable financial impacts.
