Description

In a society in constant technological evolution, companies try to equip themselves with tools that allow them to achieve, or maintain, the leadership position in the markets in which they compete in. Success often lies in the ability to exploit the existent Business Intelligence (BI) in the best possible way. Moreover, mobile devices such as smartphones and tablets assume themselves as elements with an increasingly preponderant use in the everyday life. In the convergence of these two factors, emerges the need to develop mobile “management facilitators”, capable of providing companies’ workers the access to BI, anywhere and at a few touches distance. To make this possible, not only does the correct information needs to be selected, but also organized and presented in a highly intuitive and easy to use way. It’s in this context that the work present in this dissertation emerges: User-Centered Design of the interface prototype of a Business Intelligence mobile application for a company in the retail industry. Thus, the goal of this dissertation resides in the development of an adequate interface, through the continuous interaction with a group of representative users in activities such as users’ needs assessment, interface design, heuristic evaluation and usability tests. From meetings with the users, 29 needs were identified for the BI application. These needs were later converted into functional requirements which originated two prototypes, one for smartphones and the other for tablets. These were subjected to a heuristic evaluation and tested through the application of the Cognitive Walkthrough method to representative users, to collect performance and satisfaction metrics. It was concluded that the designed interfaces were in accordance with 14 of the 16 heuristics, which led to three modifications on the interfaces. The Cognitive Walkthrough results showed that the interfaces are intuitive since all the tasks were completed with 100% success, in reasonable times and with a number of actions close to the ideal.
