Although the high quality of software is important for software stakeholders, quality of software products is often not effectively defined. Some quality models have been proposed, but these conventional models cannot measure and evaluate software product quality comprehensively. Moreover, quality measured and evaluated based on organization-specific quality models cannot be compared to the quality of other software products. To alleviate this problem, ISO/IEC defined international standards called the SQuaRE (Systems and software Quality Requirements and Evaluation) series for comprehensive quality measurement and evaluation; however, these standards include ambiguous measurements, making them difficult to apply. In this paper, we propose a comprehensive quality measurement framework, which includes a clear measurement plan based on ISO/IEC 25022 and 25023. We confirmed the usefulness of our framework by conducting a case study of applying our framework to a commercial software product.As future work, we will introduce our framework to various domains. And then, we revise and refine measurements and evaluation plans to improve feasibility and usefulness.

The goals of this workshop are finding the relations of handover patterns, specifying the priority of the patterns, finding possible new patterns, and sharing the experiences of handovers.

We propose a method to compare software products developed by the same company in the same domain. Our method, which measures the time series of the number of detected faults, employs software reliability growth models (SRGMs). SRGMs describe the relations between faults and the time necessary to detect them. Herein our method is extended to classify past projects for comparison to current projects to help managers and developers decide when to end the test phases or release a project. Past projects are classified by three parameters: lines of code, number of test cases, and test density. Then SRGM is applied. Our extended method is applied to the datasets for nine projects developed by Sumitomo Electric Industries, Ltd. Classification by test density produces the best results.

In order to pay appropriate attention to system qualities, it is important that quality is enabled and infused into the prioritized work throughout the whole process. This paper presents three patterns for Enabling and Infusing Quality: System Quali ty Specialist, Spread the Qual ity Workload, and Automate First. System Quality Specialists can help to define, test, and implement complex quality items that are complex and require a lot of expertise to get right. Spreading the Quality Workload throughout the development process can help keeps the team from being overburdened with quality tasks. Automating First what you can to streamline your build and testing processes enables you to eliminate tedious or mundane tasks allowing more time for team members to focus on implementation and testing of important qualities.

In 2007 issues with handovers became apparent in Japan, when many people from the Baby Boomer Generation retired simultaneously. Most business people are familiar with the concept of a handover. Although effective handovers are crucial for seamless business operations during personnel changes, the preferable elements for a handover are ambiguous and not well researched. This motivated us to examine this topic. We held a workshop on handovers to assess actual problems due to undesirable handovers. The results were used to elucidate three handover anti-patterns, which identify concrete problems of handovers. To mitigate the problems, we found a pattern language for handovers by analyzing three anti-patterns. Herein, we outline a pattern language for handovers.

Hironori Washizaki, Yann-Gael Gueheneuc, Foutse Khomh, “Patterns for Program Reverse Engineering from the Viewpoint of Metamodel,” 23rd Conference on Pattern Languages of Programs (PLoP 2016), Monticello, Illinois, USA, OCTOBER 24-26, 2016. (to appear)(CORE Rank B)

Reverse engineering tools often define their own metamodels according to their purposes and intended features. These tools and metamodels have advantages that may benefit other metamodels as well as limitations that other metamodels may solve. To guide practitioners (and researchers) in selecting, integrating, and using appropriate tools, we propose a preliminary pattern catalog for program reverse engineering from the program metamodel viewpoint based on our conceptual framework in consideration of both grammarware and modelware approaches. The catalog consists of one metapattern, Transformation to higher abstraction levels, and three concrete patterns, Integrated program reverse engineering, Fact extraction, and Architecture recovery. The intended audience of these patterns is practitioners (and researchers) such as software maintainers who desire to comprehend a program. In addition, these patterns may be helpful for tool developers (and researchers) creating reverse engineering tools.

Hironori Washizaki, Juan Garbajosa, “Proposals for the SWEBOK evolution process from the viewpoint of ISO/IEC/JTC1/SC7 standardization activities,” IEEE CS SWEBoK Evolution Virtual Town Hall Meeting, Aug 25, 2016 (to appear)

ISO/IEC/JTC1/SC7 Software and Systems Engineering, recognized that SWEBOK is an internationally-accepted body of knowledge in software engineering so that ISO/IEC published SWEBOK 2004 and V3 as ISO/IEC technical reports ISO/IEC TR 19759:2005 [ISO19759:2005] and ISO/IEC TR 19759:2015 [ISO19759:2015] respectively. Within SC7, Working Group 20 (WG20) Software and systems bodies of knowledge and professionalization in collaboration with IEEE processed their standardization and publication processes. During these processes, we encountered some issues and considered possible corresponding countermeasures. In this paper, we recommend three countermeasures for further evolution of SWEBOK from the viewpoint of standardization within SC7: 1) Evolution process with active involvement of SC7 and WG20. 2) Alignment with ISO/IEC 24773:2008 [ISO24773] and related standards developed within SC7. 3) Eligibility criteria for knowledge areas based on market recognition such as job offers.
