Quality Assurance in Agile Distributed Software Teams
No full textThis report is written as part of the graduation of master of science in computer science, information architecture, at the Delft university of technology, the Netherlands. I started this research when an opportunity presented itself for a case study in Mauritius. It was not the trip abroad what interested me but the case to lift a team to a higher level of software quality. During my research I got more interested in software quality assurance. Especially because I noticed that on many of the developer’s priority lists, it has a low priority. Software quality assurance is often observed as an obligation instead of a handy tool. My true motivation for this research was to see if I could change this. In this research the challenge was to develop a newapproach for quality assurance within agile distributed development environments. The research was started as follow-up of several interviews performed with experts in the area of software development in which the opportunities in the field were observed. The research presented in this report can be of value for all software development engineers, with orwithout expertise in quality engineering. The research might particularly be relevant if searching for structured approaches for improving software processes or products. Next to these specific groups, anyone who is interested in software quality (assurance), agile (distributed) approaches or the challenges in these, can obtain relevant and interesting information from this report. For the guidance I experienced during my thesis I would like to thank Rini van Solingen, my mentor at the University and Toine Hurkmans, who acted as mentor at Exact Software. I would further like to thank Exact Software for the opportunity of conducting a case study and in special the Titan, Research and System team for their cooperation. Further thanks goes to Sander Kruger and Global Edge Software who offered the opportunity for performing the orientating case study.Electrical Engineering, Mathematics and Computer ScienceSoftware Engineerin
Globally Distributed Agile Release Trains
No full textSAFe is a framework that applies both agile and lean practices for developing software. The current trend is that increasingly more organizations develop their software in a globally distributed setting. Although SAFe is being deployed in such a setting, SAFe was not originally developed for such a setting but for a co-located setting. Therefore, this research investigates the application of SAFe in globally distributed settings. Five problems are discovered that can be expected to fail when SAFe is applied in distributed settings: incorrect execution of SAFe, language barriers, time zone differences, increased communication effort, and inefficient communication tools. Given these problems, four SAFe elements are identified that can be expected to fail when SAFe is applied in distributed settings: the PI planning, the inspect & adapt meeting, the DevOps team, and the system team. Finally, a customization of SAFe for distributed settings is proposed. This customization is focused on solving the discovered problems for the elements identified to fail.Electrical Engineering, Mathematics and Computer ScienceSoftware TechnologyInformation Architecture trac
Visualization of SysML Project Meta-Model Architecture and Evolution
No full textLarge and complex projects, such as infrastructure, often require the collaboration of multiple parties and disciplines, where an structured interdisciplinary methodology is necessary: Systems Engineering. This field traditionally relied on a document based approach, but is currently transitioning to a model based variant, with the Systems Modeling Language as one of its main standards. Visual modeling platforms, such as Enterprise Architect, allow to design and construct models in SysML. However, these tools lack proper measurement and visualization functionality to deal with project specific meta-model architectures. To overcome these limitations a software tool was developed using the extract-abstract-present paradigm: VoSMA. Also, multiple measurements were developed applying the Goal-Question-Metric approach, and different visualization methodologies were explored to present this information. Three SysML tunnel projects were analyzed as test case studies to assess the usefulness and correctness of the generated data, and multiple feedback sessions were conducted with experienced systems engineers. The results are very promising and indicate that the data generated may greatly benefit project development. Based on the results of the evaluation and the achieved progress, some suggestions and possible future directions were provided at the end of this study.Computer ScienceDepartment of Software and Computer TechnologyElectrical Engineering, Mathematics and Computer Scienc
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
