Motivational Modelling in Software for Homelessness: Lessons from an Industrial Study

Abstract

Requirements engineering involves the elicitation, representation and communication of diverse stakeholder needs. However, this can be particularly challenging when developing technology embedded within complex social systems. So-called socially-oriented requirements can be abstract, ambiguous and driven by the organisational, cultural and political contexts of the stakeholders involved. Motivational models are one solution which supports project-wide understanding of the key goals of stakeholders. Yet, there is still a lack of understanding about the role they can play in larger industrial projects. We present our use of motivational modelling in an Australia-wide project that develops new technology to assist people who are homeless in accessing service providers. We interviewed 100 stakeholders and utilised motivational models to advocate for the needs of key stakeholder groups. We discuss the benefits, challenges and lessons learned.
