Abstract What are the key aspects to achieving acceptable usability outcomes for information systems being developed? The changing technologies and increased usage across the general population, the impacts of this in our everyday lives, at work and at leisure are exponentially increasing. The interfaces and interaction styles presented as part of these technologies have been challenged to be more intuitive, contextually sensitive, location aware, human centred and aimed at a larger community of stakeholders. Performing usability activities is an increasingly important part of the development of new technologies, applications and websites. This study examined, for Information System projects, what were the key aspects that impacted on the usability outcome of developing Information Systems.

This study presents a theory that describes how projects can improve their usability outcomes. This has emerged from interviews with experienced usability practitioners currently working in the usability industry. The transcripts from the qualitative interviews were analysed using a grounded theory methodology, which was an inductive and interpretive process in nature. The result of this analysis produced twenty-seven key concepts. These concepts were compared and contrasted against the literature.

The theory that emerged consists of four major themes that included: usability mindset, collaborative approach, project constraints and usability practice. The key contribution to knowledge is the relationship concept between these themes. This is the nurturing of the usability mindset for the project stakeholders through involvement in usability activities throughout the project lifecycle. This engagement provides opportunities to elicit, understand and concord the usability goals, project constraints and the technological limitations with project stakeholders. The involvement of all project stakeholders promotes usability value and acceptance, which ideally progresses to a shared usability vision for the project and ultimately a usability mindset that can be utilised beyond a specific project and across an organisation.
