Most people use one or more other devices other than personal computers to obtain information services. In fact, many times more people in the world use mobile phones than personal computers, and many use PDAs or other devices. The proliferation of devices and network alternatives is a challenge for service system designers. If a service provider’s intended customers use different or multiple devices, the service must be designed to work on all of them. But there is little consensus about the best approach for designing services to run on multiple devices or platforms.
