Knowledge patterns are one way to formalize and describe lessons learned and best practices (i.e., proven experiences) about structuring knowledge, the design of KM systems, or the development of underlying ontologies. Such patterns capture aspects that positively or negatively influence the KM activities. In the later case, where negative influenc...

Knowledge management is a relatively young discipline. Nevertheless, it has accumulated a valuable body of knowledge in the structuring of knowledge and in the design of socio-technical knowledge management systems. However, concepts to describe common, recurring patterns of how to describe, structure, interrelate, group, or manage knowledge elemen...

Students have to cope with new technologies, changing environments, and conflicting changes in capstone projects. They often lack practical experience, which might lead to failing to achieve a project’s learning goals. In addition, the Net Generation students put new requirements upon software engineering education because they are digitally litera...

A part of software quality assurance is concerned with the diagnosis of defects, which decrease quality aspects of software systems, such as maintainability, reusability, portability, or performance. Concurrent approaches for defect diagnosis focus on post-development manual inspections of the software's source code. The context-sensitive diag-nosi...

However, quality assurance application in the domain of software models and model-driven software development is still in an emergent phase. Model-Driven Software Development: Integrating Quali...

Additional information about software models comes in different forms such as defects detected, design patterns used, traceability information to other abstraction levels, etc. In this paper, we present how additional informa-tion about defects, context, traceability, etc. can be embedded into UML-and BPMN-based PIM-and CIM-level software models. F...

Knowledge management is a relatively young discipline. It has accumulated a valuable body-of-knowledge on how to structure and represent knowledge, or how to design socio-technical knowledge management systems. A wide variety of approaches and systems exists that are often not interoperable, and hence, prevent an easy exchange of the gathered knowl...

A Learning Software Organization (LSO) often supports such information retrieval needs by installing an Experience Base (EB) or another Knowledge Management (KM) system. However, even in such environments, searching for the right information can still be a challenge. In this paper, we identify some of the reasons for these challenges. Based on our...

Software engineering curriculum guidelines state that students should practice methods, techniques, and tools. A capstone project is one possibility to address this aim. A capstone project helps the students to increase their problem solving competencies, improve their social skills (e.g., communication skills), and gather practical experience. A c...

Software projects in small-and medium-sized enterprises (SMEs) produce similar work products when building interactive software systems. For each project, software engineers create requirements, design specifications, source code, data schemes, and so forth, gain experience with these work products, and create associated products such as test cases...

Although many environments explicitly or implicitly use ideas from intelligent assistance research, users aren't always aware of its existence and potential. A survey of 135 German participants sheds light on the usage of and demand for intelligent assistance in software engineering activities. The project aimed to clarify intelligent assistance co...

Requirements elicitation and documentation are complex activities. So, not only the requirements themselves but also the people involved and the means for managing the requirements will evolve during the project. For example, it might be necessary to add RE personnel, to document templates, or to change the requirements classification scheme. In su...

Software systems have reached a level of complexity that puts them beyond our ability to evolve and maintain them easily. This increases the need for soft-ware organizations to develop new or rework existing systems with high quality. CodeSonar was developed to support software engineers during software development and maintenance activities throug...

Trends are a valuable tool to shape one's research, decide on acquisitions, inform about technologies or standards used in the development process.
