Magda Huisman is the Research Director of the Unit for Business Mathematics and Informatics at the North-West University in South Africa. She is a Professor of Computer Science and Information Systems and teaches software engineering, IT project management,  management information systems, and decision support systems. She received her Ph.D degree in Computer Science and Information Systems in 2001. Prof. Huisman is actively involved in research projects regarding systems development methodologies. She has published her research in journals such as MISQ, Inf­ormation & Management, IADIS International Journal on Computer Science and Information Systems, IJWEST, and Lecture Notes in Computer Science. Her current research interests are in the use and effectiveness of systems development methodologies and the diffusion of information technologies.

With the increase in the adoption of mobile devices, the demand for mobile applications also increases. While some mobile applications are very successful, others fail. In this paper we will try to answer the question: "What factors influence the success of mobile applications, and is the use of systems development methodologies one of these factors?" To answer this question, we will focus on the user acceptance of mobile applications and the development process of mobile applications. The factors (positive and negative) that influence user acceptance of mobile applications will be presented, as well as the results of a study on the use and effectiveness of systems development methodologies during mobile application development.
