Business process variability is an active research area in the field of business process management and deals with variations and commonalities among processes of a given process family. Many theoretical approaches have been suggested in the last years; however, practical implementations are rare and limited in their functionality. In this paper, we propose a new approach for business process variability...
Processes in hospitals or in other healthcare institutions are usually analyzed and optimized isolated for enclosed organizations like single hospital wards or certain clinical pathways. However, many workflows should be considered in a broader scope in order to better represent the reality, i.e., in combination with other processes and in contexts of macro structures. Therefore, an integrated view...
IT environments that consist of a very large number of rather small structures like microservices, Internet of Things (IoT) components, or mobility systems are emerging to support flexible and agile products and services in the age of digital transformation. Biological metaphors of living and adaptable ecosystems with service-oriented enterprise architectures provide the foundation for self-optimizing,...
Requirements Engineering has recently been greatly influenced by the way how firms use Open Source Software (OSS) and Software Ecosystems (SECOs) as a part of their product development and business models. This is further emphasized by the paradigm of Open Innovation, which highlights how firms should strive to use both internal and external resources to advance their internal innovation and technology...
Our experience with email-based marketing campaigns (or short: “Microservices”) showed that they are an intersecting set of a) projects and processes and b) technology and creativity. Their properties of fixed due date, fixed scope and at the same time fixed duration render classical management methodologies unfeasible. The same applies to the supporting enterprise infrastructure architecture, where...
During recent years, there has been an increasing interest in the potential opportunities that can be attained with promoting Smart Cities; a concept that can be reached based on Information and Communication Technology (ICT). The Smart Cities concept is considered achievable by horizontal integration of a number of vertical industries in order to empower sustainability and improvements on quality...
In traditional product companies, creating value meant identifying enduring customer needs and manufacturing well-engineered solutions. Two hundred and fifty years after the start of the Industrial Revolution, this pattern of activity plays out every day, especially in a connected world where products are no longer one-and-done. Making money is not anymore limited to physical product sales and other...
Small and medium enterprises (SMEs) are often described as the engine of growth for a country's economy due to their significant economic contributions. At the same time, ebusiness offers an opportunity for SMEs to significantly further their growth as it has been identified as a tool that could improve an enterprise's operational efficiency and competitiveness in the global market. Despite the promised...
Cloud service-based applications are to be adapted to serve multiple platforms and stakeholders. Atop of such services, Smart Green Buildings are fostering a plethora of processes within their sustainability life-cycle. This introduces a number of challenges, as how to support multiple perspectives of domain-specific variability and how to deal with large collections of related process variants. To...
Cloud federation is a new paradigm in Cloud Computing. It helps the Cloud Service Providers (CSPs) to overcome the limitation of their own resources to serve their clients. The CSPs can negotiate the possibility to borrow external resources from each other when their own facilities are not able to satisfy their client requests. Reciprocally, the CSPs may sell some of their unused resources to another...
The increasing availability of digital data offers new opportunities for analyzing business processes. Process aware information systems like Enterprise Resource Planning systems store data in the course of transaction processing. This data can be exploited by using process mining techniques. Process mining algorithms produce process models by analyzing recorded event logs. A fundamental challenge...
i∗ is a goal-oriented and agent-oriented modeling framework that focuses on the analysis of intentional and strategic relationships among actors. In this mini-tutorial, we highlight a number of recent applications in practical industrial and business settings.
Requirements Engineering involves different stakeholders and their different views of a system. Among these stakeholders, software designers are responsible for modeling the information gathered by domain experts. The communication between these specialists is not always easy, often leading to a semantic gap between what is desired and what is developed. This gap is characterized by inconsistencies...
In the recent years the following two trends have been accelerated: on the one hand, as Content Services became at the center of Internet usages, OTTs strengthen their position. On the other hand, in several cases, Telcos are seeing their role shrinking to “dumb pipes” providers. This paper introduces advanced Telcos' positioning in future content distribution services. In particular, it focuses on...
This paper presents Halos Networks as an architectural paradigm for developing ubiquitous networking and computing services at the edge of the networks A Halos Network is like a wireless network spontaneously emerging through the interactions of distributed resources embedding wireless communication capabilities. Halos Networks are capable of delivering services and data virally through multiple devices,...
Empirical results in business research derived from multiple linear regression models are often susceptible to issues of dimensionality and multicollinearity. We extend the current research practices for addressing multicollinearity by introducing an original method, Bayesian Dominance Hierarchy (BDH) to determine the relative importance of predictors in a multiple regression context.
This research explores the connection between online consumption and online community participation activity. Using longitudinal data that contains detailed information about 4,475 online poker players' gaming activity and online community activity over 58 months, this paper finds that the general positive relationship between consumption and community activity is very strong at the level of the community,...
Representation and formalization of value models and constellations do not only affect companies' strategies. Even within the process level, the contribution of activities to the value chain has to be obvious to enhance understanding. One important aspect to reach correspondence between the strategic value-oriented business model level and business process level is consistency in modeling. Therefore,...
The objective of this paper is to put forward a discussion of how a better understanding of the issues surrounding control can be an important element in the development of generativity strategies in business models for mobile platforms, such as Apple's iPhone. Generativity refers to “a technology's overall capacity to produce unprompted change driven by large, varied, and uncoordinated audiences”...
