In cognitive psychology, confirmation bias is defined as the tendency of people to verify hypotheses rather than refuting them. During unit testing software developers should aim to fail their code. However, due to confirmation bias, most defects might ...

We propose a set of quantitative metrics to empirically evaluate security quality levels on an Open (Software) Engineering Service Bus (EngSB) platform.

Software testing is an important process for software quality control, and it is also costly and time-consuming. It can easily take 50% of development time [1]. To gain high quality software, a frequently-adopted approach is to try to minimize the number ...

The engineering of complex software-intensive systems, like industrial production plants, requires software engineering to coordinate and interact with other engineering disciplines. Project and quality managers need empirical study results to improve ...

This paper presents a methodology to detect and measure the complexity of traceable transactions from requirements (use cases) to code (source code) of a system.

This extended poster abstract presents a software visualization tool (CodeVizard) that helps researchers and managers to analyze software repository data. The tool focuses on identifying areas of risks in software development projects, such as: Code ...

Eleven open source software projects were analyzed to determine if the number of committing developers impacts code quality. We use cyclomatic complexity, lines of code per function, comment density, and maximum nesting as surrogate measures of code ...

Commonly enterprise systems are implemented using the object-oriented and relational paradigms, among which the communication is performed using various library methods for manipulating the persistent data. Most of the times the involved library methods ...

In this poster we introduce an ongoing empirical study on the effects of using predominant security issues along with agile methodologies. As part of this empirical study, current security issues related to and applicable to agile methodologies such as ...

Various design patterns have become known for increasing the adaptability of software, so reducing the cost of maintenance and evolution. In this study the focus was placed on the performance cost of using such patterns with the research question 'How ...

Several projects rely on one or more Heroes who are the only ones who understand and know certain critical parts of a system. Often Heroes are very useful in the economy of a project but, their presence can increase the risk of project failure if they ...

The challenge of developing more usable Web applications has promoted the emergence of several usability evaluation methods. However, there is a lack of empirically validated methods that can properly be integrated during the early stages of Web ...

A critical claim in software requirements regards the assertion that the team performances improve when media with higher richness levels are used. To investigate this claim, we have conducted a controlled experiment to compare traditional face-to-face ...

In case of resolved software change requests (SCRs), the names of impacted source files are known. In this paper, we tackle the question whether it is possible to use this information in order to predict the files that have to be changed whenever a new ...

Software inspections are effective ways to detect defects early in the development process. In this paper, we analyze the impact of certain defect types on the effectiveness of code inspection. We conducted an experiment in an academic environment with ...

Models are key artifacts in Model-Driven Development (MDD) methods. To evaluate the quality of models, defect detection is considered to be a suitable approach, which is usually applied using reading techniques. However, new techniques are required in ...

Individual differences of developers in performance and introduced defects have been reported by many research studies and are frequently observed in software development practice. Thus, when the source of defects in the final product is discussed, ...

Fixing bugs and implementing enhancements are very relevant activities in a typical software life cycle. They require, as a pre-requisite, the location of a portion of impacted code within a possibly large codebase. This operation can be extremely ...

We report on a preliminary case study to examine software safety risk in the early design phase of the NASA Constellation spaceflight program. Our goal is to provide NASA quality assurance managers with information regarding the ongoing state of ...

Software practitioner motivation has been recognised as a key factor in system quality, yet much of what we know about practitioner motivation is based on research conducted decades ago. In this paper, we present the analysis of data collected from 23 ...
