A retail company reviews last quarter's sales records to find out which products sold best in each state and why sales dipped in one region. Which type of analytics is being used?
The company is using descriptive and diagnostic analytics. Summarising past sales by state shows what happened, and investigating the regional dip explains why it happened. Forecasting future sales would be predictive, and recommending actions would be prescriptive, neither of which the scenario involves.
