Traditional information systems (IS) development adopts a systematic approach for conducting analysis, design, and testing, without necessarily using a specific user model that personalizes the system to one or more user groups. This quasi-experimental study of multi-cases explores introducing novice developers to two User-centered Design tools- user profiles and personas-as a part of the systems analysis and design methodology. Profiles and personas are structured ways of typifying a group of users in text and pictorial form (e.g., conceptually modeling the users). The study results indicate developers find both tools are useful in capturing the team's understanding of user groups and meeting end users' objectives; though, profiles seem to have a slight edge over personas. In addition, case analysis indicates the use of user profiles and personas may produce design and implementation deliverables that enhance alignment with system objectives and end users.
