Mobile business applications (mobile business apps) bear huge potentials for increased work productivity, work comfort, and even sales if they are of high quality. Usability and user experience, in particular, are among the key quality attributes. The high quality requirements of mobile business apps require them to be thoroughly engineered. Unfortunately, today's software engineering approaches are often too heavy-weight to allow developing highquality mobile business apps in the context of mobile projects, which often face small budgets, extremely limited effort, and short time-to-market requirements. This paper presents mConcAppt, a user-centered and lightweight conception method for mobile business apps. It provides guidance for requirements engineering and interaction design for mobile business apps and provides interfaces to other activities, such as visual design, architectural design, implementation, and testing. The adoption of mConcAppt in various industrial contexts indicates that it enables organizations to elaborate a concept for a highquality mobile business app in 2-4 weeks.
Providing interactive mockups of mobile applications in designing phases introduces new challenges for interaction designers compared to the traditional way of static mockups. In particular, the complexity of this process increases when it comes to enabling the user to actually explore the intended user experience of the mobile environment by enhancing traditional handmade sketches or tool-generated wireframes with concrete mobile interaction elements. We introduce a framework, called i2ME (interactive Mockup-Building for Mobile Environment), for building interactive mockups with concrete mobile interaction elements. The framework enhances the static mockups (handmade or tool-generated) with screen transitions and multi-touch gestures, and enables the deployment of the resulting HTML5+JavaScript based interactive mockups to multiple platforms and device classes.
