The BA needs to consider metrics and key performance indicators (KPIs) when using basic statistical sampling concepts to measure the objective of a solution implemented. Metrics and KPIs are quantitative measures that are used to evaluate the performance, progress, and value of a solution, process, or activity. They can help the BA to determine if the solution is meeting the expected outcomes and benefits, and to identify any gaps, issues, or opportunities for improvement. Metrics and KPIs can also help the BA to communicate the results and impact of the solution to the stakeholders and the organization. Some examples of metrics and KPIs that can be used to measure the objective of increasing the number of customer calls resolved per hour are: average call duration, first call resolution rate, customer satisfaction score, and call resolution efficiency. Frequency and timing, financial analysis, and benchmarking and market analysis are not the best options to consider when using basic statistical sampling concepts, because they are either too general, too specific, or not directly related to the objective of the solution.
