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.

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.

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.

(CORE Rank B)(to appear)

OSS (Open Source Software)-based software developments tend to have a lot of defects when editing program source code files that other organizations created. Developments with complex origins and functional layers are increasing in OSS-based development. As an example, here we focus on an Android smart phone development project and propose new visualization techniques for product metrics based on the file origin and functional layers. One is the Metrics Area Figure, which can express duplication of edits by multiple organizations intuitively using overlapping figures. The other is Origin City, which was inspired by Code City. It can represent the scale and other measurements, while simultaneously stacking functional layers as 3D buildings. The contributions of our paper are to propose new techniques, implement them as web applications, and share the results of our questionnaire experiment. Our proposed techniques are useful not only to visualize measured metrics, but also to improve product quality.

Software development that considers privacy protection is required with the progress of information and communication environments. However, a body of knowledge does not exist for developing privacy-aware software. This paper introduces studies that address knowledge regarding the development of privacy-aware software based on a literature survey, and de-scribes current status and future direction intended toward building a knowledge base for privacy-aware software development.

ソフトウェアの品質を把握し、管理および改善するためには、測定を通じた評価が欠かせない。しかし、思慮なく測定評価を導入すると、誤った結論を導くなど、かえって悪影響をもたらしかねない。本稿では、筆者が所長を務める早稲田大学グローバルソフトウェアエンジニアリング研究所が産学官連携により進めているソフトウェア品質測定評価の研究および実践結果に基づき、得られた知見を4つの「落とし穴」および7つの「コツ」として整理し解説する。
