B.1.2 A Web-Based Supermarket
A supermarket wants to start a subsidiary that offers web-based order
entry and delivery services to its customers. The way in which the system
for such a subsidiary should operate is as follows. The orders are picked from
stock in the existing stores, but the subsequent deliveries are carried out by
local subcontractors; these are engaged as necessary to meet demand. The
orders are transferred from the order entry website to mobile devices in the
stores, where staff assemble the order ready for delivery. Confirmation of the
order list is printed with the delivery instructions and passed to the delivery
drivers. Scheduling information about forthcoming deliveries is provided to
the delivery company while the orders are being assembled.
You are asked to develop the ODP enterprise, information and computa-
tional specifications for the system that will support this business.

A Loyalty-Points System
A third-party company offers loyalty bonuses for a variety of existing ser-

support to primary service providers, including software components that the
primary providers can incorporate into their designs. There is a requirement
for uniform rules for bonus collection to be applied in all aliated services,
based on the distribution of common code. However, it must be easy to inte-
grate the support for bonus points into existing provider applications.
Write the enterprise specifications of the system, with particular emphasis
on its interactions with the communities that represent the rest of the aliated
companies. Once the enterprise specification is written, you are asked to
develop the information and computational specifications, focusing on how
the system will interact with the IT systems of the aliated companies.
