Operate it

A catalog is never finished. The checks, the weekly loop, and what to do when a product will not appear.

Go-live is where catalog work changes shape. A supplier sends a new feed with the material spelled a different way than last year. Purchasing stops a range that forty customers still order from a 2019 price list. The model you built is fine; this is what a live catalog does every week.

These pages are the maintenance loop: a check you run on a schedule, the mass edits that keep coming back, and the stages a product passes through between "new from the supplier" and "no longer supplied".
