The purpose of this work was both to explore the variety of methods to develop mobile applications and to create a requirement documentation and solution proposal to the case study Rundtursbuss. During the 10 weeks work-experience, I had the possibility to investigate a range of methods to develop mobile applications and apply it to a reference case. The questions regarding which method to choose when developing mobile application are not easy to answer, once there is not only one solution that can fit the needs of all the applications that will be developed at Scania. Each application needs to be evaluated not only from a technical perspective, but also from a user-centered way. One of the best ways to quickly evaluate a project is asking what that makes the project mobile The analysis of each criteria aided in the evaluation of the application requirements and in reaching the conclusion that the most promising methods to develop the application Rundtursbuss are either native or cross-compilation ones. In conclusion, it is crucial to emphasize that while Scania does not have a procedure on how to develop, maintain and coordinate the development of mobile applications, single initiatives will continue to emerge, which increase the cost and affect the quality of their IT products and services.
