Context: Agile software processes are more frequently being integrated with aspects of human centered design given the commonalities that the two approaches share, such as user involvement, importance attributed to testing and prototyping practices, iterative design and so on. Goal: tailor a SCRUM-based process by integrating it and adapting it with Human Centered Design (HCD) practices. Method: action...
In this work, we report a study carried out to identify a set of metrics to early estimate the development effort of mobile apps. The applied methodology was inspired by the work of Mendes et al. who addressed a similar problem in the field of web apps. In particular, we extracted an initial set of metrics by analyzing the online quotes forms that companies made available on their websites. Afterward,...
Software start-ups are a new and relatively unexplored field for software engineering researchers. However, conducting empirical studies with start-ups is difficult. Start-ups produce very little "hard" evidence, thus data collection methods are limited to interviews and surveys. These methods come with their limitations, namely interview studies are not scalable to a large number of companies,...
Continuous improvement, feedback mechanisms and automated testing are cornerstones of agile methods. We introduce the concept of test analytics, which brings these three practices together. We illustrate the concept with an industrial case study and describe the experiments run by a team who had set a goal for itself to get better at testing. Beyond technical aspects, we explain how these experiments...
A Massive Open Online Course (MOOC) is a popular way for universities to deliver quality course content to a global audience. Furthermore, a MOOC specialization offers a series of related such courses with a capstone component. Typical software engineering capstone projects in campus courses involve teamwork and creating software. Within such a context, students experience the software development...
Job Rotation is an organizational practice in which individuals are frequently moved from a job (or project) to another in the same organization. Studies in other areas have found that this practice has both negative and positive effects on individuals’ work. However, there are only few studies addressing this issue in software engineering so far. The goal of our study is to investigate the effects...
Context: While successful conventional software development regularly employs separate testing staff, there are successful agile teams with as well as without separate testers. Question: How does successful agile development work without separate testers? What are advantages and disadvantages? Method: A case study, based on Grounded Theory evaluation of interviews and direct observation of three agile...
Context: Software development is knowledge-intense work, and so is pair programming. However, the importance of knowledge transfer in pair programming is usually only stressed for expert-novice constellations. Goal: Understand how knowledge transfer during pair programming works and eventually provide guidance for practitioners. Method: Detailed qualitative data analysis of full-length recordings...
The popular agile practice of continuous integration has become an essential part of the software development process in many companies, sometimes to the extent that delivery to customer is impossible without it. Due to this pivotal role it is an important field of research to better understand the practice: continuous integration system behavior, improvement identification and analysis of change...
Crowd-based requirements engineering (CrowdRE) could significantly change RE. Performing RE activities such as elicitation with the crowd of stakeholders turns RE into a participatory effort, leads to more accurate requirements, and ultimately boosts software quality. Although any stakeholder in the crowd can contribute, CrowdRE emphasizes one stakeholder group whose role is often trivialized: users...
This work aims to purpose the creation of a model to develop intelligent learning systems with self-regulated contents. Its main goal is to support self-oriented learning in workplace, to improve performance levels and skills. Our target is mainly software industries, where the novelty of knowledge and learning needs are critical success factors for the companies' competitiveness, and the learning...
Context: To be more flexible, companies call more and more for an independence between development tools and processes. To enable this form of decoupling we need to understand the interrelation of processes and development tools. However, knowledge about that field is rare.Goal: The goal of this study is to better understand how technologies in use might impact the processes and team interaction.Method:...
Very recently, an increasing number of software companies adopted DevOps to adapt themselves to the ever-changing business environment. While it is important to mature adoption of the DevOps for these companies, no dedicated maturity models for DevOps exist. Meanwhile, maturity models such as CMMI models have demonstrated their effects in the traditional paradigm of software industry, however, it...
Context: It is well known that in software engineering, software or system development processes are very important for getting a high quality product. Such processes can be described in many different ways, from textual documents to existing modeling notations. Objective: Before dealing with the overall goal of improving the description of development processes, this paper evaluates what process...
Effort estimation is more challenging in an agile context, as instead of exerting strict control over changes in requirements, dynamism is embraced. Current practice relies on expert judgment, where the accuracy of estimates is sensitive to the expertise of practitioners and prone to bias. In order to improve the effectiveness of the effort estimation process, the goal of this research is to investigate...
Over the decades, a variety of software development processes have been proposed, each with their own advantages and disadvantages. It is however widely accepted that there is no single process that is perfectly suited to all settings, thus a software process should be molded to the needs of its situational context. In previous work, we have consolidated a substantial body of related research into...
The proper alignment of requirements engineering and testing (RET) can be key to software's success. Three practices can provide effective RET alignment: using test cases as requirements, harvesting trace links, and reducing distances between requirements engineers and testers. The Web extra https://youtu.be/M65ZKxfxqME is an audio podcast of author Elizabeth Bjarnason reading the the Requirements...
Learning Analytics is the measurement, analysis, and reporting of data about learners and their contexts, for the purposes of understanding and optimizing learning and the environments in which it occurs. Civitas Learning has created a suite of learning analytics tools and employed early versions of this software at Valencia College in Orlando, Florida. We explore the use of this tool in three instructors'...
The endless pursuit for creating effective systems for software reuse has continued for as long as software has existed. To date, there have been few, if any, such effective systems created for ensuring a high degree of reusability from one project to the next. The inherent tendency for projects to demand substantial alterations, despite being designed for maximum reusability, remains strong evidence...
This paper presents an approach, based on the multi-criteria method SMARTER, that can be useful to support decisions involving the selection of the best-fit agile software development methodology for small and medium enterprises. The kickoff of this study was a research regarding measurable criteria that should be considered in this type of decision aiming to answer the needs of specific projects...
