The increased usage of technology requires the user interface to be user friendly and easy to understand. In portals, the user interface is one of the critical components. Portal is a medium that Small Medium and Macro Enterprises (SMME) can use to advertise, grow exposure of their business and interact with their customers and community at large. This requires the portal interface to adapt to runtime changes because of the rapid update of services. This research work addressed the issue of analysis of user request in order to have a clear understanding of the request. This is achievable by taking into consideration the user history, preference and profile. This work is realizable through the use of the design of architectural model, the Dynamic User Interface (DUI) model which analyzes the user request and also aggregate different components and presents them as a single unit to the user. The DUI model was prototyped via Grid-based Utility Infrastructure for SMME-enabled Technology (GUISET) user interface use case. Experiments were conducted to compare DUI portal and Jetspeed-2 to test usability subjects. Usability was evaluated under four experiment variations: customization, adaptation after query, user satisfaction with response and portal performance. For each experiment, data was generated and graphically presented for analysis. The results obtained show scalability of the portal interface with regards to the increased number of users requesting for the same services and the increased number of portlets. The user satisfaction with the interface adaptation on the fly after the query and content is also shown on the results that were obtained after the experiments.
