HCI engineering integrated with capability maturity models: A study focused on requirements development

Even though coming from different communities, Software Engineering (SE) and Human-Computer Interaction (HCI) engineering have similar goals: the definition of methods, techniques and standards to support the development of software systems, and, in particular for HCI, of interactive systems. Currently, several SE approaches are largely applied in practice thank to the widespread use of capability maturity models in companies. To benefit from this situation and taking advantage of the similarity of SE and HCI goals, we have studied how to support the developers that use these models with approaches from HCI while developing interactive systems. In this paper we present the part of this study regarding requirements development process, an undoubtedly important area from software life cycle. This study involves a detailed analysis of one of the most known models (the CMMI-DEV - Capability Maturity Model Integration for Developers) and interview with twenty experts in HCI domain. As result, a set of HCI approaches to support the developers in the requirements development process area is presented.
