Architecture decision records (ADRs) have been proposed as a resource-efficient means for capturing architectural design decisions (ADDs), and have received attention not only from researchers but also from practitioners. We conducted a mining software repositories (MSR) study, in which we analyzed the use of ADRs in open source repositories at Git...

Technical standards help software architects to identify relevant requirements and to facilitate system certification, i.e., to systematically assess whether a system meets critical requirements in fields like security, safety, or interoperability. Despite their usefulness, standards typically remain vague on how requirements should be addressed vi...

To support the vision of Industry 4.0 and smart factories, manufacturing companies need to evolve their machines towards intelligent, connected cyber-physical systems (CPS). Software is at the heart of these digital transformation processes. OPC UA (Open Platform Communications Unified Architecture) is an industrial standard for horizontal and vert...

With the proliferation of AI-enabled software systems in smart manufacturing, the role of such systems moves away from a reactive to a proactive role that provides context-specific support to manufacturing operators. In the frame of the EU funded Teaming.AI project, we identified the monitoring of teaming aspects in human-AI collaboration, the runt...

In the industrial domain, developing solutions that allow the identification, understanding, and correction of faults is essential due to the cost of handling such situations. However, to date, there are not many solutions capable of facilitating the human operator to discern the causes and possible solutions for a specific fault. In this work, we...

Recent advances in deep learning facilitate the training, testing, and deployment of models through so-called pipelines. Those pipelines are typically orchestrated with general-purpose machine learning frameworks (e.g., Tensorflow Extended), where developers manually call the single steps for each task-specific application. The diversity of task- a...

Knowledge graphs in manufacturing and production aim to make production lines more efficient and flexible with higher quality output.

While user-centered design (UCD) processes have widely been established in domains like end-user electronics and business-to-consumer products, such processes still lack widespread adaptation for the development of industrial human-machine interfaces (HMIs). Over a period of more than two years, we have worked as part of a development team at a com...

We are interested in specifications which provide a consistent high-level view of systems. They should abstract irrelevant details and provide a precise and complete description of the behaviour of the system. This view of software specification can naturally be expressed by means of Gurevich’s Abstract State Machines (ASMs). There are many known b...

Architecture conformance checking is an important technique to verify whether a software system's implementation adheres to predefined architectural rules. The adherence to architectural rules is crucial, since architectural rules are intended to ensure that fundamental properties are correctly implemented in the source code. A lot of tools have be...

Formal approaches are a prerequisite for automated quality control. However, such approaches are often difficult to learn and apply and thus have not found their way into mainstream software development. Controlled natural languages (CNLs) seek to overcome the drawbacks of formal approaches by hiding their formality behind a restricted set of natur...

Microservice architecture focuses on splitting up software systems into a suite of services to support independence at the development, deployment, and operational levels. To support this independence, the introduction of a microservice architecture also requires changes to the team organization and operational infrastructure. As a consequence, int...

The SCCH research focus Software Analytics and Evolution (SAE) is researching methods and tools for the development and evolution of software-intensive systems that meet increasing demand for user-friendliness. Furthermore, SAE addresses software quality assurance by systematic testing (e.g., test automation, test case generation, compositional tes...

Source code and related artifacts of software systems encode valuable expert knowledge accumulated over many person-years of development. Analyzing software systems and extracting this knowledge requires processing the source code and reconstructing structure and dependency information. In analysis projects over the last years, we have created tool...

Introducing a microservice system is a challenging task and requires the exploration and documentation of several related areas of design. Exploration and documentation of software architecture design is supported by decision guidance models in software architecture. In this paper, we present such guidance models for several microservice system des...

Microservice architectures promise high flexibility and sustainability in system development. Multiple principles have emerged for the successful adoption of microservices, principles which impact not only the technical but also the organizational levels of a development organization. This paper reports our experiences introducing microservices in...

Introducing a microservice architecture is a complex task, requiring many design decisions regarding system architecture, organizational structure, and system infrastructure. Decision models have been successfully used in other domains for design space exploration, decision making and decision documentation. In this paper, we investigate the use of...

Context: Automated test generation promises to improve the effectiveness of software testing and to reduce the involved manual effort. While automated test generation has been successfully applied for code-level API testing, it has not found widespread adoption in practice for testing of graphical user interfaces. Tools for test generation do not s...

Changes may cause unexpected side effects and inconsistencies. Regression testing is the process of re-testing a software system after changes have been made to ensure that the new version of the system has retained the capabilities of the old version and that no new defects have been introduced. Regression testing is an essential activity, but it...

Manufacturing execution systems (MES) are key elements of industrial automation systems. MES can be deployed at different levels of scale from a single site or plant to a company with globally distributed production sites all over the world. Establishing or extending an MES is a complex process, which requires taking the already existing software a...

Architectural knowledge is an important artifact for many software development and quality control activities. Examples for qual- ity control activities based on architectural information are architecture reviews, dependency analyses, and conformance analyses. Architecture is also an important artifact for understanding, reuse, evolution, and main-...

We report on service development and architecture management practices for an enterprise SOA in the financial domain. First we describe how services are currently developed by one of the largest service providers for the financial domain in Austria. Then we show how we have introduced various practices and tools for architecture management over the...

Company-wide reference architectures are an important means for standardization and reuse. Standardization is enforced through reference architecture conformance checking. Manual conformance checking is too time- and resource-intensive to be performed continuously for the various systems that are part of a SOA. We present an approach for automatic...

This chapter discusses software architecture analysis in the context of agile processes. Agile processes are characterized by incremental and interleaved activities and by a focus on continuous improvement and delivery. Most approaches to software architecture analysis, however, have been developed to be performed at dedicated points in the develop...

Reference architectures (RA) are reusable architectures for artifacts in a particular domain. They can serve as a basis for designing new architectures, but also as a means for quality control during system development. Quality control is performed through checking the conformance of systems in development to (company-wide) reference architectures....

Manual regression testing can be a time-intensive and costly activity. Required efforts can be reduced by selecting only the tests for re-testing that verify actually modified system parts. However, if testers are not familiar with the system implementation the selection of relevant test cases may become difficult. In this paper we report on our ex...

In enterprises using service-oriented architecture (SOA) architectural information is used for various activities including analysis, design, governance, and quality assurance. Architectural information is created, stored and maintained in various locations like enterprise architecture management tools, design tools, text documents, and service reg...

Software architecture is a central element during the whole software life cycle. Among other things, software architecture is used for communication and documentation, for design, for reasoning about important system properties, and as a blueprint for system implementation. This is expressed by the software architecture life cycle, which emphasizes...

Traceability requires capturing the relations between software artifacts like requirements, architecture and implementation explicitly. Manual discovery and recovery of tracing information by studying documents, architecture documentation and implementation is time-intensive, costly, and may miss important information not found in the analyzed arti...

Current software development environments lack support for architecture-related activities like architecture design, analysis, and architecture knowledge management. We present a toolkit supporting architecture-centric development. The toolkit is an extension of the Eclipse IDE and supports architecture-related activities during the whole software...

It has been proposed to make architectural design decisions first-class entities in software architecture representation. The actual means of capturing, representing, and managing architectural design decisions is still an open issue of research. We present an approach for capturing requirements and design decisions during design and development. W...

Software architecture analysis is a central activity in software development. Multiple software architecture analysis techniques exist, which differ in cost and complexity, the addressed stakeholders and the supported kinds of analysis. To support comprehensive software architecture analysis, multiple analysis techniques need to be applied within o...

Informal and formal approaches to documenting software architecture design offer disjoint advantages and disadvantages. Informal approaches are often used in practice since they are easily accessible and support creativity and flexibility during design. But they are hard to maintain and validate. This is the strength of formally defined approaches,...

Principles of component-based software construction like decomposition, decoupling, late binding and late composition are mainstream concepts found in many software systems, technologies and domains. The definition of individual components and component properties is well supported on the level of programming languages. However, tool support for co...

Software architectures are still typically defined and described independently from implementation. To avoid architectural erosion and drift, architectural representation needs to be continuously updated and synchronized with system implementation. Existing approaches for architecture representation like informal architecture documentation, UML dia...
