Why reporting was not working
Each country ran its POS as a separate, unlinked network: its own credentials, its own currency, its own set of locations. The loyalty program lived in a third system, delivery aggregators in a fourth, costs in spreadsheets.
Because of that, a simple question — «how did the week go» — turned into a project: collect exports, normalize currencies, remember where a promo ran, and still end up with a week-old picture.
At that latency, management decisions are made on instinct. A location's decline shows up in money a month later instead of as a signal the next morning.
