Adaptation of Orthogonal Defect Classification for Mobile Applications

As mobile applications have become popular among end-users, developers have intro- duced a wide range of features that increase the complexity of application code. Orthogonal Defect Classification (ODC) is a model that enables developers to classify defects and track the process of inspection and testing. However, ODC was introduced to classify defects of traditional software. Mobile applications differ from traditional applications in many ways; they are susceptible to external factors, such as screen and network changes, notifi- cations, and phone interruptions, which affect the applications’ functioning. Therefore, in this paper, the ODC model will be adapted to accommodate defects of mobile applications. This allows us to address newly introduced application defects found in the mobile domain, such as energy, notification, and Graphical User Interface (GUI). In addition, based on the new model, we classify found defects of two well-known mobile applications. Moreover, we discuss one-way and two-way analyses. This work provides developers with a suitable defect analysis technique for mobile applications.

Software Defect Prevention through Orthogonal Defect Classification (ODC)

“Quality is never an accident; it is always the result of intelligent effort” [10]. In the process of making quality software product, it is necessary to have effective defect prevention process, which will minimize the risk of making defects /errors in software deliverables. An ideal approach would involve effective software development process with an integrated defect prevention process. This paper presents a Defect Prevention Model in which Defect Prevention Process(DPP) is integrated into software development life cycle to reduce the defects at early stages itself, thereby reducing the defect arrival rate as the project progresses to the subsequent stages. Orthogonal Defect Classification (ODC) scheme involving defect trigger, defect type etc. are discussed in this work to illustrate how ODC can be used in the defect prevention process. ODC can be used to measure development progress with respect to product quality and identify process problems, which will help to come out with “Best Practices” to be followed to eradicate the defects in the subsequent projects.
