In order to see if process assessment drives processes learning, process assessments were performed in the capstone project of a Bachelor in Computer Science. Assessments use an ability model based on a small subset of ISO/IEC 15504 processes, its main Base Practices and Work Products. Students' point of view was also collected through an anonymous questionnaire. Self-assessment using a competency...
The software industry presents dissatisfaction in relation to the level of recently graduated professionals. Consequently, software companies end up investing in the training of these professionals in order to develop skills related to the software development process. This paper presents an experience report of an adaptation of industry training practices in a course of Software Engineering (SE)...
In industry, the benefit of maturity models is uncontested, and models like CMMI are normally taught in at least advanced Software Engineering courses. However, when not being part of real-world projects, the added values are difficult to be experienced on first hand by our students. In this paper we report on a study and teaching approach where, in three successive semesters and at two different...
Over Several years, we observed that our students were sceptical of Software Engineering practices, because we did not convey the experience and demands of production quality software development. Assessment focused on features delivered, rather than imposing responsibility for longer term `technical debt'. Academics acting as 'uncertain' customers were rejected as malevolent and implausible. Student...
As continuous delivery and continuous integration practices become more prevalent in industry, the need for education in these areas grows. Introducing these topics introduces complexities due to the learning curve of the involved tools and the amount of time available for teaching these topics. Furthermore, there has been limited research into effective teaching practices for incorporating continuous...
Background: Several mobile app releases do not find their way to the end users. Our analysis of 11,514 releases across 917 open source mobile apps revealed that 44.3% of releases created in GitHub never shipped to the app store (market). Aims: We introduce "marketability" of open source mobile apps as a new release decision problem. Considering app stores as a complex system with unknown...
Textual description of requirements is a specification technique that is widely used in industry, where time is key for success. How requirements are specified textually greatly depends on human factors. In order to study how requirements processing is affected by the level of detail in textual descriptions, this paper compares enriched textual requirements specifications with non-enriched ones. To...
Background: While bug bounty programs are not new in software development, an increasing number of companies, as well as open source projects, rely on external parties to perform the security assessment of their software for reward. However, there is relatively little empirical knowledge about the characteristics of bug bounty program contributors. Aim: This paper aims to understand those contributors...
Background: Experiment-driven development with the help of real usage data helps to build software products and services that are of high value to their users. As more software companies use experimentation in their development practises, ethical concerns are increasingly important. Objective: There is a need for understanding the ethical issues companies must take into account when practising experimentation...
Context: In organizational psychology literature, Task Variety and Skill Variety are considered different aspects of work design. Albeit related to different aspects of the work, it is common to find strong correlations between these constructs. After applying the Work Design Questionnaire (WDQ) on a sample of 102 software professional, we found the similar correlations and conjectured that they were...
Background: Although there has been a significant amount of research focused on designing and conducting controlled experiments, few studies report how experienced experimental software engineering researchers actually design and conduct their studies. Aims: This study aimed to offer a practical perspective from their viewpoint regarding controlled experiment planning. Method: We collected data through...
Context. Member checking can be defined as a research phase performed during a qualitative research in which the researcher compares her interpretations and understanding obtained from the data analysis with the view-points of participants to increase accuracy and consistency of results. This is an important step for any qualitative research. However, considering a sample of 66 case studies developed...
Continuous Integration(CI) is a widely used development practice where developers integrate their work after submitting code changes at central repository. CI servers usually monitor central repository for code change submission and automatically build software with changed code, perform unit testing, integration testing and provide test summary report. If build or test fails developers fix those...
Dependency-based software change impact analysis is the domain concerned with estimating the sets of artifacts impacted by a change to a related artifact. Research has shown that analysing the various class dependency types independently will never completely reveal the impact sets. Therefore, dependency types are combined to improve the precision of estimated when compared to impact sets. Software...
Understanding developer productivity is important to deliver software on time and at reasonable cost. Yet, there are numerous definitions of productivity and, as previous research found, productivity means different things to different developers. In this paper, we analyze the variation in productivity perceptions based on an online survey with 413 professional software devel-opers at Microsoft. Through...
Context. Considering the importance of software testing to the development of high quality and reliable software systems, this paper aims to investigate how can work-related factors influence the motivation of software testers. Method. We applied a questionnaire that was developed using a previous theory of motivation and satisfaction of software engineers to conduct a survey-based study to explore...
Software defect prediction is one of the most attractive research topics in the field of software engineering. The task is to predict whether or not a program contains semantic bugs. Previous studies apply conventional machine learning techniques on software metrics, or deep learning on source code's tree representations called abstract syntax trees. This paper formulates an approach for software...
Electrocardiogram (ECG), Electrodermal Activity (EDA), Electromyogram (EMG) and Impedance Cardiography (ICG) are among physiological signals widely used in various biomedical applications including health tracking, sleep quality assessment, early disease detection/diagnosis and human affective state recognition. This paper presents the development of a biosignal-specific processing and feature extraction...
Even the most innovative healthcare technologies provide patient benefits only when adopted by clinicians and/or patients in actual practice. Yet realizing optimal positive impact from a new technology for the widest range of individuals who would benefit remains elusive. In software and new product development, iterative rapid-cycle “agile” methods more rapidly provide value, mitigate failure risks,...
This paper presents both the theoretical approach and the HOMER software approach for the planning of optimum long-term microgrid. The proposed microgrid system comprises of solar, wind, energy storage, diesel generator and converter systems. The microgrid objectives of this work are to be at lowest net present costs and emissions. Hence, the theoretical approach will be using modelling equations...
