The importance of information security in software development projects is long recognised, with many comprehensive standards and procedures in use to provide assurance of information security. The agile development paradigm conflicts with traditional security assurance by emphasising the delivery of functional requirements and a reduction in struc...

As teams and organisations make the difficult shift to agile ways of working, there has been relatively little investigation of how they adopt and use agile practices. To aid those teams looking to move to agile we should examine how others have done so and what practical value they found. We studied teams which adopted agile practices across a spe...

Gamification of software engineering tasks improve developer engagement, but has been limited to mechanisms such as points and badges. We believe that a tool that provides developers an interface analogous to computer games can represent the gamification of software engineering tasks more effectively via software visualization. We introduce CityVR...

Many visualizations have proven to be effective in supporting various software related tasks. Although multiple media can be used to display a visualization, the standard computer screen is used the most. We hypothesize that the medium has a role in their effectiveness. We investigate our hypotheses by conducting a controlled user experiment. In th...

Software systems are not static, they have to undergo frequent changes to stay fit for purpose, and in the process of doing so, their complexity increases. It has been observed that this process often leads to the erosion of the systems design and architecture and with it, the decline of many desirable quality attributes, such as maintainability. T...
