Yasuhiro Watanabe, Hironori Washizaki, Kiyoshi Honda, Yuki Noyori, Yoshiaki Fukazawa, Aoi Morizuki, Hiroyuki Shibata, Kentaro Ogawa, Mikako Ishigaki, Satiyo Shiizaki, Teppei Yamaguchi and Tomoaki Yagi, “ID3P: Iterative Data-Driven Development of Persona based on quantitative evaluation and revision,” 10th International Workshop on Cooperative and Human Aspects of Software Engineering (CHASE 2017), collocated with ICSE 2017, Buenos Aires, Argentina, May 23, 2017.

Personas are fictional characters used to understand users’ requirements. Many researchers have proposed persona development methods from quantitative data (data-driven personas development), but practical issues about running a service have yet to be discussed. This paper proposes Iterative Data-Driven Development of Personas (ID3P). In particular, to detect a change in users’ characteristics, our proposal includes an iterative process where the personas are quantitatively evaluated and revised in each iteration. ID3P helps service manager who are unfamiliar with UX techniques to understand about users on a web service quantitatively. Moreover, it provides a quantitative evaluation of business strategies based on GQM+Strategies and personas. To verify our proposal, we applied it to Yahoo!JAPAN’s web service called Netallica.

Defect Analysis and Prediction by Applying the Multistage Software Reliability Growth Model, accepted at IWESEP 2017 (collocated with ICST 2017)

Jieming Chi, Kiyoshi Honda, Hironori Washizaki, Yoshiaki Fukazawa, Kazuki Munakata, Sumie Morita, Tadahiro Uehara, and Rieko Yamamoto, “Defect Analysis and Prediction by Applying the Multistage Software Reliability Growth Model,” The 8th IEEE International Workshop on Empirical Software Engineering in Practice (IWESEP), pp.1-5, Tokyo, March 13, 2017. (to appear) (acceptance rate 9/18=50%)

In software development, defects are inevitable. To improve reliability, software reliability growth models are useful to analyze projects. Selecting an expedient model can also help with defect predictions, but the model must be well fitted to all the original data. A particular software reliability growth model may not fit all the data well. To overcome this issue, herein we use multistage modeling to fit defect data. In the multistage model, an evaluation is used to divide the data into several parts. Each part is fitted with its own growth model, and the separate models are recombined. As a case study, projects provided by a Japanese enterprise are analyzed by both traditional software reliability growth models and the multistage model. The multistage model has a better performance for data with a poor fit using a traditional software reliability growth model.

Closing the Gap between Unit Test Code and Documentation accepted at InSTA 2017 (collocated with ICST 2017)

Karsten Stöcker, Hironori Washizaki and Yoshiaki Fukazawa, “Closing the Gap between Unit Test Code and Documentation,” 4th International Workshop on Software Test Architecture (InSTA 2017), Tokyo, 2017 Mar 17.

Test Driven Development as well as the documentation of tests and their architecture are today an important pillar of software quality assurance. The change of requirements during the implementation phase entails a need to change tests as well as the test documentation of the software. Since unit tests are specified in the implementation language, an interdisciplinary readable documentation must be maintained, which is structurally easier to comprehend and also make the test transparent for persons who are not involved into code writing. This leads to additional effort, costs and possibly inconsistencies between the test and its documentation. This gap in the workflow could be closed by Tanni – a domain specific language, which allows the specification of test cases in the form of interdisciplinary readable tables without requiring programming skills. Based on them executable test code for the respective unit test framework is generated. This merges specification and documentation of unit test cases to one step of work. By this the mentioned additional effort, costs and imminent inconsistencies can be reduced. The Language Workbench Meta Programming System from JetBrains serves as a technological base and is enabler for further positive effects which possibly could be gained by using the described language.

CSEE&T 2017 Call for Submissions

The 2017 IEEE Conference on Software Engineering Education and Training (CSEE&T) is taking place in Savannah, Georgia, in November 2017. Since the first CSEE&T, software engineering education has changed a great deal. In 1986, software engineer-ing education was largely undertaken by industry, with just a few academic software engineering programs in place. Since then, software engineering degree programs have emerged at all levels, and we are seeing increased attention to software engineering specialty areas. Software engineering professionalism initiatives resulted in the certification and licensing of software engineers in a number of countries worldwide.

On the industry side, we are seeing an upheaval in software engineering as we know it. Innovations such as cloud computing, autonomous vehicles, drones, bioengineering, and other initiatives have made for a rapidly changing landscape. Topics such as software assurance, safety, and reliability have become important knowledge areas. As educators, we are challenged to keep up with the emerging trends. We are in a global economy with a software supply chain that can extend across many countries and regions, and each one has its own regulations and laws about safety, security, and privacy. Software engineers change jobs fre-quently, so the value of in-house training is not as clear as it once was. At CSEE&T 2017, we will focus on the changes taking place in the field, discuss our response to them, and form a vision of how to move forward to meet the ever-increasing demand for qualified software engineers.
