Experiences with a dialog-driven process model for Web application development

We present a dialog-driven process model for the development of Web-based applications that uses a graphical notation to model and iteratively refine the application's dialog flow, and communicate with non-technical stakeholders in the development process. This way, the user interface can drive the design and implementation of the application logic and data model instead of being dictated by it. After an introduction of the underlying notation and dialog control framework, we present how these tools can support the phases of the development process and discuss experiences gained from the implementation of a Web application that was built using this approach.
