We envision a next generation fault - tolerant point - of - sale (POS) application, NextGen POS, with the flexibility to support varying customer business rules, multiple terminal and user interface mechanisms, and integration with multiple third - party supporting systems.
Existing POS products are not adaptable to the customer's business, in terms of varying business rules and varying network designs (for example, thin client or not; 2, 3, or 4 - tier architectures). In addition, they do not scale well as terminals and business increase. And, none can work in either on - line or off - line mode, dynamically adapting depending on failures. None easily integrate with many third - party systems. None allow for new terminal technologies such as mobile PDAs. There is marketplace dissatisfaction with this inflexible state of affairs, and demand for a POS that rectifies this.
Traditional POS systems are inflexible, fault intolerant, and difficult to integrate with third - party systems. This leads to problems in timely sales processing, instituting improved processes that don't match the software, and accurate and timely accounting and inventory data to support measurement and planning, among other concerns. This affects cashiers, store managers, system administrators, and corporate management.

Key High - Level Goals and Problems of the Stakeholders
A one - day requirements workshop with subject matter experts and other stakeholders, and surveys at several retail outlets led to identification of the following key goals and problems:
User - Level Goals
The users (and external systems) need a system to fulfill these goals:
The NextGen POS will usually reside in stores; if mobile terminals are used, they will be in close proximity to the store network, either inside or close outside. It will provide services to users, and collaborate with other systems, as indicated in Figure Vision.
