As part of an overall quality initiative at General Electric (GE), a study was undertaken to understand and reduce usability defects in the software development lifecycle at GE Information Services, Inc. Six Sigma methodology, which tries to increase quality through systematic process improvement, was applied to a sample of usability data. The results of this effort found that usability defects were highest in those products where there had been minimal involvement of the User Interface staff and usability defects were most dramatically reduced by using a systematic approach to usability (i.e., the user interface design process). When presented to upper management, the net effect of this study was a raised consciousness in the company that usability defects are very controllable, a policy statement issued that future development efforts would include the user interface design process, and a commitment for increased resources for the User Interface team.

This chapter presents the information architecture approach for the design of an administration tool for educators to manage educational oriented recommendations in virtual learning environments. In this way, educators can be supported in the publication stage of the e-learning life cycle after recommendations have been designed with the TORMES methodology. The chapter starts introducing relevant background information on recommender systems for e-learning and the rationale for the educators’ involvement in the recommendation design process. Afterwards, the chapter comments on the information architecture that supports the user interface design process with user-centered design methods, including the goals to achieve in each of the steps defined. The chapter ends by discussing the application of this approach in different contexts.
