1. Visualize the evolution of call volume and call topics over the first few months of a loan’s life cycle. What metrics are most important to track? What trends do you observe? What hypotheses do you have regarding these trends? 2. How might you track this data over time, and how would you operationalize this data with different cross-functional stakeholders (i.e. product, operations, compliance, etc.) 3. We can set up alerts based on spikes in call volume. How would you determine a good threshold for an alert? 4. What additional data points would improve this dataset to get a better understanding of customer support and servicing performance? How might you go about procuring these additional data points?
