Software engineering process models for mobile app development: A systematic literature review

Context An effective development model can help improve competitive advantage and shorten release cycles, which is vital in the fast paced environment of mobile app development. Objective: The aim with this paper is to provide an extensive review of existing mobile app development models. Method: The review is done by following a systematic literature review process. Also presented is an assessment of the usefulness and relevance to industry of the models based on a rigor and relevance framework. Results: 20 primary studies were identified, each with distinct models. Agile methods or state-based principles are commonly adopted across the models. Relatively little effort focuses on deployment, maintenance, project evaluation activities. Conclusion: The review reveals that the contexts in which the identified models are intended to be used vary. This benefits practitioners as they are able to select a model that suits their contexts. However, the usefulness in industry of most of the models, based on the contexts in which the models were evaluated, is questionable. There is a need for evaluating mobile app models in contexts that resemble realistic contexts. The review also calls for further research addressing special constraints of mobile apps, e.g., testing apps on multiple-platforms, user involvement in release planning and continuous deployment.
