DynaDesigner is a tool for creating, testing, and deploying interactive services to be delivered on devices such as telephones, TVs, and PCs. A key feature is that it supports device-independent service design -a service is designed once, independent of any particular device. This eases the design and maintenance task for service providers and makes services easier for consumers to use, since they are consistent across devices. DynaDesigner has been used to design and deploy many services. With DynaDesigner, services can be designed and deployed in hours.
