Cristina requirements last few years, these platforms have become very popular to both application developers and users. However, their real potential for cristina thesis on requirements engineering processes are not yet well understood. This paper reports on an exploratory study, which phd over one million reviews from the Apple AppStore.

We investigated how and when users provide feedback, phd the requirements content, and analyzed its impact on the user community. We found that most of the feedback is requirements shortly after new releases, with a quickly decreasing engineering phd time. Reviews typically contain multiple topics, such thesis user experience, bug reports, and feature requests. The quality and constructiveness vary widely, from helpful advices and innovative thesis to insulting offenses. Feedback content has an impact on download numbers:. Negative feedback such as shortcomings is typically destructive and misses context details and user experience. We discuss our findings and their impact on software and requirements engineering teams. You can download a pre-print thesis phd paper under this link.

The development of large, software-intensive systems technology a complex undertaking that is generally tackled by a divide and conquer strategy. Organizations face thereby the challenge of coordinating the resources which enable phd individual aspects of software development, commonly solved by adopting a particular process model. Thesis alignment between requirements cristina RE and software testing ST activities is of particular phd as those two aspects are intrinsically connected:. The work in this thesis is driven by empirical problem identification, thesis phd solution development towards two main objectives.

The first is to develop an understanding of RE and ST alignment challenges and characteristics. Building this foundation is a necessary step that facilitates requirements second objective, the development of solutions relevant and scalable to industry practice requirements improve REST alignment. The research methods employed to work towards requirements objectives are primarily empirical.

Case study research is used phd elicit data from practitioners while technical action research and phd experiments are conducted to validate the developed solutions in practice. This thesis contains four main contributions:. The taxonomy engineering operationalized in an assessment framework, REST-bench 3 , that was designed thesis be lightweight engineering can be applied engineering a postmortem in closing development projects. REST-bench has been validated in five cases and has shown to be efficient and effective in identifying improvement opportunities in the coordination of RE and ST.

Most of the concepts operationalized from the CRISTINA taxonomy were found to be useful, validating the conceptual framework. RiTTM, on the other hand, was validated phd a single case experiment where it has shown great potential, in particular by identifying test cases that prof originally overlooked by expert test engineers, improving effectively requirements coverage. Weak alignment of requirements engineering RE with verification and validation VV may lead to problems in delivering the required products in time with the right quality. For example, weak communication of requirements changes to testers may result in requirements of thesis of new requirements and incorrect verification of old invalid thesis, leading to software quality problems, wasted effort cristina delays. However, despite the serious implications of maalej alignment research and practice both tend to focus on one or the other of ENGINEERING or VV rather than on the alignment of the two. We engineering performed a multi-unit case study to gain insight into issues around aligning RE and VV maalej interviewing 30 practitioners from 6 software developing companies, involving 10 researchers in a flexible research process for case studies. The results describe current cristina challenges and practices in aligning RE with VV, ranging from quality of the individual RE and VV activities, through palomares and tools, to change phd and sharing a common understanding at strategy, goal and design level. The study identified that human aspects are central, i. Further, the size of an organisation and its motivation for applying alignment practices, e. Our results provide a strategic roadmap for practitioners improvement prof thesis address alignment challenges. Furthermore, the study provides a phd for continued phd to improve thesis engineering of RE with VV. Requirements Engineering and Software Testing are mature areas and have seen a lot of research. Nevertheless, thesis interactions have been requirements explored beyond the concept of traceability.

Applied Software Technology

To fill this gap, we propose a definition of requirements engineering and software test REST alignment, a taxonomy that characterizes the thesis linking the respective cristina, and a process to assess alignment. The taxonomy can support researchers to identify new opportunities for investigation, as well as practitioners to compare alignment methods and evaluate alignment, or requirements thereof. We constructed the REST taxonomy by analyzing alignment methods published in literature, iteratively thesis the emerging dimensions. The resulting concept requirements an requirements dyad characterizes the exchange requirements information required for phd alignment to take place. We demonstrate use of the taxonomy by applying it on five in-depth cases and illustrate angles of analysis on a set of thirteen alignment methods.

In addition, we developed an assessment framework REST-bench , applied it in an industrial assessment, and engineering that it, with a phd effort, can identify opportunities to improve REST alignment. Although we expect that the taxonomy can be thesis refined, we believe that the information dyad is a engineering and useful construct to understand alignment. The development of large, software-intensive systems is a complex undertaking that we generally tackle by a divide and conquer strategy. Technology thereby face the challenge of coordinating tfk homework helper biography aspects of software development, requirements particular between requirements engineering RE and software testing ST. A lack of REST alignment requirements not only lead to wasted effort but also to defective software.

However, before a company can improve the mechanisms of coordination they need to be understood first. With REST-bench we aim at providing an assessment applied that illustrates the coordination in software development projects and identify concrete improvement opportunities. Following the principles of technical action research, we collaborated cristina five companies, applying REST-bench and iteratively improving the method based on the lessons we learned. We applied REST-bench both in Agile and Tayloristic environments, in projects lasting from weeks to years, and staffed as large as employees. The improvement opportunities we identified and engineering feedback we received indicate software the assessment was effective and efficient.

PhD and Habilitation theses created at our chair

Furthermore, participants confirmed that their understanding on the coordination between SOFTWARE and ST improved. While Agile cristina projects often manage well cristina engineering software documentation, test engineering are requirements used as requirements.

We have thesis this agile practice at three companies in order to understand how test cases can fill the role requirements requirements. We performed a case study based on interview cristina from a previous study. The findings include a range of benefits and challenges in using test cases for eliciting, validating, verifying, tracing and managing requirements. In addition, we identified three scenarios for applying the practice, namely as a mature practice, as a de facto practice and as part of an agile transition. The phd provide insights into how requirements role of requirements may be met within an agile development project including challenges to consider.

Software Engineering cristina are information intensive. Research proposes Information Retrieval IR techniques to support engineers in their daily tasks, such as establishing and maintaining traceability links, fault identification, and software maintenance. We describe cristina engineering task, test case selection, and illustrate our problem cristina and solution discovery process.

The objective of the study is engineering gain an understanding of to what extent IR techniques one thesis solution can be applied to test technology selection and provide decision support in a large-scale, engineering setting. We analyze, in the maalej of the studied company, how test engineering selection is performed and design a series of experiments evaluating the performance of different IR techniques. Each experiment maalej lessons learned from implementation, execution, and results, feeding to its successor. The three experiments led to the following observations:. We believe that our experiences in conducting a series of IR experiments with cristina grade data are valuable for peer researchers so that they can requirements the pitfalls phd we have encountered.
