Quality Validation for Mobile Embedded Software

Many mobile applications have evolved from simple HTML pages to complex service-oriented applications that have high maintenance cost. This high maintenance cost is due to the heterogeneity of mobile applications, to the fast mobile evolution and to the fast-moving market which imposes short development cycles and frequent modifications. In order to control the maintenance cost, quantitative metrics for predicting mobile applications' maintainability must be used. This study introduces class diagram design metrics based on Conallen's Mobile Application Extension for UML. The study will use data from an industrial mobile application to show the correlation between the class diagram metrics and maintenance effort measured by the number of lines of code changed.
