As a consequence of the necessities of the digital age, agility is becoming more and more important in software development. Consequently, agile change management is increasingly coming into focus and many projects are undergoing a transformation process from classic software development to agile software development. Through this, managers are con...

Retail is expected to be one of the industries that will benefit most from advances in artificial intelligence (AI) in the future. One branch of AI is video analytics, which is used to analyze the behavior, flow, and interactions of customers in a store. Properly implementing features to optimize store operations, prevent theft, or provide targeted...

With the significance, ubiquity, and complexity of information technology continuously rising, the corresponding quality assurance becomes increasingly important and challenging. Consequently, numerous tools, techniques, paradigms, and strategies that facilitate the quality assurance of the developed applications have emerged. Test-driven developme...

With the increasing relevance of decentralisation for the software development process, being aware of the possible challenges and corresponding solutions has become more relevant than ever. The scientific body of knowledge is currently containing many publications about specific aspects of decentralisation, but is lacking in collections that cover...

For almost a decade now, big data has become the foundation of today's data-intensive systems used for various disciplines, such as data science or artificial intelligence. Although a certain level of maturity has been reached since then, not only in the domain itself but also in the engineering of interconnected systems, many problems still exist...

The ongoing digitization of our world leads to many areas of our lives being more pleasant and improved. New technologies and paradigms are emerging to support the development of software and systems. Their proliferation not only leads to higher complexity of potential solutions, but also to the problem of finding qualified people. Especially enter...

As big data is a rather young, but growing discipline, lots of confusion about the general nature of this term exists. Consequently, multiple research endeavours to discover unique characteristics, technologies, techniques and their interconnections were conducted, resulting in comprehensive classification approaches. For this purpose, various taxo...

IT administrators are fundamental to effective IT operations but are challenged by outsourcing and technological as well as organizational change. This paper investigates how four companies in their operations of SAP-focused enterprise systems organize and carry out tasks. A literature-based frame of inquiry is used to gather information from four...

Companies embrace digitalization to have a shorter time to market. This drive for digitalization also demands that the quality of products and services is high. Containerization is one of the concepts that are core to achieve these objectives in information technology today as it is central to the development and delivery of software products. Ther...

Big Data is a crucial pillar for many of today’s newly emerging business models. Areas of application range from consumer analysis over medicine to fraud detection. All of those domains require reliable software. Even though imperfect results are accepted in Big Data software, bugs and other defects can have drastic consequences. Therefore, in this...

Digitization raised new opportunities and challenges for organizations. Due to greater use of IT in business, extra expenses accrue to improve the IT infrastructure in these organizations. In order to deal with the new challenges and get the benefit of the new opportunities, IT Operation Management (ITOM) is a potential concept which can be used by...

In manufacturing, substantial efficiency gains have been achieved through industrialization. Key concepts of industrialization include standardization, automation, and modularization. Transferring these to IT service production promises increased efficiency. ERP systems apply such concepts and have been an integrating tool for making production for...

The rapid growth of Information Technology (IT) usage in enterprises has led to complex, heterogeneous, and dynamic IT system landscapes. Thus, a realization of efficient and effective application system landscapes is required, which in turn demands for a synchronization of activities and collaboration among all involved stakeholders. In this resea...

Information technology (IT) service providers struggle with efficient and integrated production processes when compared to modern manufacturers. Manufacturers produce products build-to-order in a mass-customization approach or engineer-to-order in a highly customized but streamlined production process while using computer-integrated manufacturing a...

IT service providers provide customers with services supporting their business. Numerous departments are involved in service planning, production and delivery, for example infrastructure, application or sales. Enterprise resource planning systems that integrate departments and which have been successful in traditional industries should be adapted t...

The digital transformation of the economy, as well as society in general, is in large part based on data centers’ capabilities to process, store, and transport data. As the range of application requirements, the volume of data and system complexities, as well as security requirements increase, appropriate application system landscapes to support th...

Flexible IT landscapes and efficient management of resources are key issues for enterprises. Variability is an important aspect for flexible IT landscape. The main part of the paper discusses variability characteristics in Infrastructure as a Service (IaaS). We show what kind of variability is possible at IaaS. In addition, a case study is provided...

Information Technology (IT) usage in enterprises has evolved over the last years. This led to today's complex, heterogeneous, and dynamic IT system landscapes that support business processes in enterprises. To manage these landscapes, the IT Service Management (ITSM) concept is gaining more importance in today's business and research. Studies demon...

Achieving efficiency gains on all levels of enterprise architecture by such means as standardization has been and is a goal of researchers and practitioners working on the provisioning of IT services. At the process level, provisioning IT services is defined in common practice frameworks like the IT Infrastructure Library (ITIL). ITIL describes a t...

Competition among software as a service (SaaS) providers becomes more pressing as new i don't like this diffing players enter the market. In order to stand competition providers require more efficient production processes. Therefore, automation is key and standardized domain conceptualizations serve as a basis for automation. Existing conceptualiza...

In this paper, we describe a procedure model for monitoring energy consumption of IT services. The model comprises the steps for identifying and extracting the required data, as well as a mathematic model to predict the energy consumption on both the infrastructure and the service level. Using the example of a distributed and shared ERP system, in...

Industrialization has led to efficiency and effectiveness gains in manufacturing industries. Industrialization approaches such as standardization or sourcing are also key concepts in modern service companies. Therefore, current IS research studies how to transfer industrialization approaches to IT service production in order to increase efficiency...

The industrialization of the IT service industry aims at transferring concepts of traditional manufacturing companies to IT service providers in order to achieve efficiency gains. Enterprise Resource Planning (ERP) systems have been irreplaceable for traditional manufacturing industries in achieving today's efficiency level. As the provisioning of...

ERP systems were fundamental in achieving efficiency gains in traditional manufacturing companies. In order to make the benefits of ERP utilizable by IT service providers, their processes need to be operationalized in ERP. IT service management (ITSM) frameworks describe these processes. They are however described using natural language. To be able...
