Calculate the average delivery time for each route and visualize the results using a box plot to identify outliers.

Perform a root cause analysis to identify factors contributing to delivery delays, such as traffic congestion or weather conditions, and visualize the results using a Pareto chart to prioritize issues.

Develop a predictive model to forecast future delivery times based on historical data and visualize the results using a time series plot to anticipate delays.

Use clustering algorithms to segment delivery routes based on their average delivery times and identify potential areas for optimization without analyzing specific delay causes.
