Starting with RESTful design is a difficult task -even more if the designer has a RPC or object-oriented background. To support the adaption from RPC-to REST-oriented thinking, we propose RESTify, a straightforward procedure model to redesign a RPC-oriented interface into a hypermediaenabled REST interface. RESTfiy uses a WSDL document of an existing SOAP service and consists of three iterations. The result of each iteration is an enhanced version of the preceding one concerning the REST constraints and is meant to be implemented as a HTTP service. Beside the technical result of the process and the design of a RESTful interface, the developer becomes acquainted to the main elements of a RESTful design, the constraints and their application. The results of the evaluation, using a prototypical web application and public SOAP services, are promising.

This paper starts from the idea that mobile enterprise software has great potential in the future but needs to fulfil usability requirements to be successful. Following mobile enterprise software Mobile enterprise software is explained with the established software engineering processes. Related to this topic usability engineering is presented with relevance to the utilization in small and medium-sized enterprises (SMEs). The relevance of the target group SMEs is demonstrated using the example of Germany. The integrated user-centered method for mobile enterprise software development integrating usability is presented. The paper closes with an analysis of the needed future research in this field.
