Usability defects can be found either by formal usability evaluation methods or indirectly during system testing or usage. No matter how they are discovered, these defects must be tracked and reported. However, empirical studies indicate that usability defects are often not clearly and fully described. This study aims to identify the state of the art in reporting of usability defects in the software...
Since usability is considered as a critical success factor for any software application, several evaluation methods have been developed. Nowadays, it is possible to find many proposals in the literature that address to evaluate usability issues. However, there is still discussion about what usability evaluation method is the most widely accepted by the scientific community. In this research, a systematic...
Usability testing is often performed on health information systems in hospital settings. Task-completion time is a frequently used measure of efficiency and a marker of successful systems. This paper presents a systematic review of the literature to determine if usability testing during the implementation of health information systems in hospitals is associated with reductions in the time necessary...
This paper presents the results of a systematic review of existing literature on the integration of agile software development with user-centered design approaches. It shows that a common process model underlies such approaches and discusses which artifacts are used to support the collaboration between designers and developers.
Test driven development (TDD) is one of the basic practices of agile software development and both academia and practitioners claim that TDD, to a certain extent, improves the quality of the code produced by developers. However, recent results suggest that this practice is not followed to the extent preferred by industry. In order to pinpoint specific obstacles limiting its industrial adoption we...
Randomized algorithms have been used to successfully address many different types of software engineering problems. This type of algorithms employ a degree of randomness as part of their logic. Randomized algorithms are useful for difficult problems where a precise solution cannot be derived in a deterministic way within reasonable time. However, randomized algorithms produce different results on...
