Making usability work in industry: an Australian practitioner perspective

The gap in usability knowledge between research and industry practice is an important one to bridge. This paper presents the findings of 12 interviews with usability practitioners. The interviews focus on eliciting stories about successful and unsuccessful usability outcomes. The analysis shows that an iterative usability process, ensuring stakeholder involvement, articulating usability goals and requirements and avoiding technological constraints are critical issues to achieving a successful usability outcome in a project.

Do you need general principles or concrete heuristics?: a model for categorizing usability criteria

This paper analyses the character of usability criteria found in lists, which are used for interface design and evaluation. In order to understand usability criteria and relations between different criteria, a categorization of six usability criteria lists has been performed. The analysis has shown that the formulations of criteria reside on different abstraction levels. The results consist of two knowledge contribution. The first contribution is a hierarchical categorization model. The role of this multilevel abstraction hierarchy is to support practical problem solving processes by enabling and supporting the explicit articulation of criteria for a given context. The second contribution is a categorization of usability criteria. The aim of this categorization is to support the understanding of how different usability criteria relate (e.g. overlap or complement) to each other and highlight possible gaps.

Factors of people-centric security climate: Conceptual model and exploratory study in Vietnam

There is an increasing focus on the persuasive approach to develop a people-centric security climate where employees are aware of the priority of security and perform conscious security behaviour proactively. Employees can evaluate the priority of security as they observe and interact with the security features that constitute the security climate of the workplace. We examined the fundamental challenge that not every employee could recognise those features. In this multi-stage research, we adopted the theoretical lens of symbolic interactionism to advance a conceptual model which explains the relationship between organisations social networks and the formation of information security climate. A descriptive case study in Vietnam was then conducted to refine the proposed model. The findings validated and extended the dimensions of information security climate, as well as identified the relevant organisations social networks (i.e. information, affect, and power) that lead to its formation.
