Transaction processing system (TPS). The point-of-sale tablets would capture every order, payment and kitchen ticket as it happens. Waiters, cashiers and kitchen staff are the users, and outputs include receipts, kitchen orders, daily sales listings and automatic matching of mobile-money and card payments, replacing paper dockets.
Management information system (MIS). Drawing on TPS data, an MIS would give branch managers and head-office managers routine reports such as weekly sales per branch, food cost percentage and waste, plus exception reports when a branch's food cost exceeds target. Results would be available days, not three weeks, after month-end.
Decision support system (DSS). Analysts and senior managers could use a DSS for what-if analysis on semi-structured problems, for example testing the effect of menu price changes on margins or modelling the best site for a new branch.
Executive support system (ESS). Wanjiru and the board would use a dashboard combining internal results with external data on competitors and meat prices, with drill-down from company totals to a single branch, to support long-term decisions on expansion and rivalry.
