How do you segment customers in last-mile delivery research?

Honestly, shipment frequency tends to be the stronger segmentation variable for last-mile — it captures urgency sensitivity and willingness to pay for speed much better than business size alone. We usually layer in a secondary split by delivery destination type (residential vs. commercial) since that drives such different expectations. If you can, run a quick cluster analysis on those two dimensions before your main survey to validate the segments hold up.
