Proposition of an m-business procedure model for the development of mobile user interfaces

In the design of desktop applications, developers successfully deploy structured software life cycle models to simplify the development process. Applying these models in m-business often does not result in usable software. M-business applications differ from desktop applications mainly in their limited user interface as well as the new mobile and dynamic application context. Traditional software life cycle models do not consider these characteristics. Although, current mobile literature describes how m-business applications must be developed, they do not give structured guidelines for the development process of mobile user interfaces. In this paper we propose an m-business procedure model for the development of mobile user interfaces. The model is based on established software engineering and human computer interaction design principles. It is concretized with detailed development recommendations regarding mobile issues and usability goals. An in-depth case study at a US software development company builds the basis for validation of the model´s practicability.
