Which of the following methods can a manager estimate the short-term demand for their company's services?

Estimating short-term demand for a company's services requires methods that can provide timely insights into current market activity. Analyzing daily sales trends is particularly effective in this capacity, as it enables managers to observe fluctuations in demand over brief periods. This method allows managers to identify patterns and react quickly to changes, helping them forecast future demand based on recent performance.

In contrast, reviewing annual reports focuses on longer-term trends and performance metrics, making it less effective for short-term estimations. Conducting employee surveys primarily gathers insights into employee satisfaction or engagement rather than market demand. Analyzing competitor performance can provide some context for demand but does not directly reflect the manager's company's current sales or service uptake. Therefore, monitoring daily sales trends stands out as the most relevant approach for assessing immediate service demand.
