Integrating Personas and Use Case Models

Abstract : Multidisciplinary design is characterized by phases of distributed work and co-design activities. An effective sharing and integration of design representations that are created by sub-teams from different disciplines is still often challenging and typically requires the reconciliation of diverging design perspectives. This paper investigates an integrated use of personas and use cases - two popular types of design representations among interaction designers and software engineers respectively. The proposed integration is particularly suitable for role-based interactive systems and differs from existing integration approaches in that it is based on a critical examination of the prevalent understandings of the goal concept in persona and use case approaches. In the paper we suggest distinguishing between organizational and user goals (while at the same time acknowledging their interplay). Corresponding adaptations to use case notations and personas are introduced and discussed. These remove the tight coupling between goals and tasks and allow integration of organizational and different persona-specific design perspectives within one use case specification and at the interaction level. As a result, interactive systems can be specified by a more compact sets of use cases. This is illustrated by an example in the context of course management systems in higher education.
