One of the least favorite parts of running old-school circulation functions 20-25 years ago was forecasting sales by hour the week a catalog was in-home.
What an awful, awful job.
A catalog would have an in-home window courtesy of the USPS (Monday - Wednesday). Your printer would deliver your catalogs deep into the USPS system, and then the USPS would deliver the catalog to the mailbox.
I had one analyst 100% dedicated to forecasting, and half of what this person did was create a forecast by hour for delivery measurement purposes (which to be fair fed our call center forecast, even though the call center had been gutted by the transition of customers to online purchases).
- 8:00am = $100,000 sales.
- 9:00am = $140,000 sales.
- 10:00am = $200,000 sales.
- 11:00am = $180,000 sales.
