Zusammenfassung Die Digitale Transformation betrifft Unternehmen aller Branchen. Diese können sich nicht auf die laufende Verbesserung ihres erfolgreichen Bestandsgeschäfts beschränken, sondern müssen gleichzeitig neue, digitale Geschäftsmodelle aufbauen, um allenfalls bereits wegbrechendes Geschäft zu kompensieren. Das Konzept der Organisationalen...
Conference Paper
Micro-electromechanical systems (MEMS) manufacturing is a highly complex process consisting of several hundred steps. The real-time data captured during those process control steps results in a huge data base. Analysis of that enormous amount of data in real-time with high sample rate during production for eventual fault detection and prediction is...
Conference Paper
Digital Innovation (DI) is the use of digital technologies during the process of innovation or as the result of innovation. While we see a huge amount of interest in DI research from IS scholars, there is still scarcity in terms of using Design Science Research (DSR) for the engineering of DI, specifically from a method perspective and a possible i...
Conference Paper
In the field of Business Process Management (BPM), planning and executing precise process tailoring and optimization can be done through different design strategies. Even though Situational Method Engineering (SME) can provide an additional layer of constitutional knowledge, it hasn’t been explored as deeply as other traditional methods. Strategies...

In this introductory article to the EIT ICT Labs we outline its innovation ecosystem and recap the underlying motives for its foundation from the perspectives of indus- try, academia and society. The EIT ICT Labs are one of the initial Knowledge and Innovation Communities (KICs) of the European Institute of Innovation and Technology (EIT) that was...
Conference Paper
Not much is known about how design knowledge is re-used in Design Science Research (DSR). The concepts of “generalization” and “transfer” as different types of knowledge-building and re-use are discussed in other disciplines and in Information System Research in general, but less so in DSR. Offermann et al. [1] proposed three ranges of design theo...

Telecommunication providers are still searching for business models beyond the bit pipe. While added-value services like Software-as-a-Service (SaaS) become more and more common for private customers as well as small and medium enterprises, in this paper we demonstrate the opportunities of Platform-as-a-Service offerings for specific business domai...
Conference Paper
Many information systems researchers designate their work as design science referring to the term “IT artifact” and the categorization systems that have emerged under this label. Alas, there is no consensus at this point as to what the research output in design science is and what types of artifacts exist. Using a widely accepted artifact typology...

Full-text available
In times of continuous change, companies need to adjust their business processes to gain sustainable competitive advantage. Resulting changes in the company's IT currently require the involvement of developers from departments that are mostly not aligned with the business. These changes often result in high transaction and labor costs. The article...

Serviceorientierte Architekturen (SOa) kombinieren Elemente der Unternehmens- und der Softwarearchitektur. Ziel ist es, flexiblere Anwendungssysteme zu erzeugen, deren Bestandteile eine hohe Wiederverwendbarkeit aufweisen. Dabei müssen gekaufte bzw. selbst entwickelte Services entsprechend den durch das SOA-System zu unterstützenden Geschäftsprozes...
Conference Paper
The SaaS-market for business process management and service orchestration is growing rapidly, fueled by the capabilities of high bandwidth and 24/7 online access. Additionally, concepts for communication support of the processes are gaining ground to increase flexibility and reduce delays. The paper introduces the concept of communication-enabled b...
Conference Paper
Service-oriented architecture (SOA) is based on a design principle for business software systems. The SOA movement has taken up momentum, especially because of widespread middleware vendor support, e.g. by IBM, HP, BEA, Microsoft, Sun, Software AG, TIBCO, Oracle, SAP and others. Still answers to questions of how the target architecture should look...
Article
This paper presents an advanced call center, which adapts presentation and interaction strategy to properties of the caller such as age, gender, and emotional state. User studies on interactive voice response (IVR) systems have shown that these properties can be used effectively to “tailor” services to users or user groups who do not maintain perso...

Conference Paper
While service-oriented architecture (SOA) is gaining momentum in research and industry, we believe the field of methods for designing information systems according to SOA still leaves room for improvement. Nevertheless, the implementation of SOA design principles demands a methodical approach. All existing methods have shortcomings of some kind, bu...

Swift and frictionless launches of new products are a decisive capability of future telecommunication providers, especially in an all-IP production environment. These processes are characterized by nonlinear, network-like dependencies of multiple stakeholders (e.g. marketing, product management, IT, production, multi-project management, controlling...
Conference Paper
While service-oriented architecture (SOA) as an architectural principle for information systems is gaining momentum in research and industry, the field of methods for designing information systems according to SOA is still poorly developed. However, the implementation of SOA design principles, e.g. service reusability, business alignment and autono...

This paper presents a comparative study of four different approaches to automatic age and gender classification using seven classes on a telephony speech task and also compares the results with human performance on the same data. The automatic approaches compared are based on (1) a parallel phone recognizer, derived from an automatic language ident...
Conference Paper
The research described in this paper focuses on possibilities of avoiding the tedious training of hidden-Markov-models when setting up a new recognition task. A major speaker independent cause of the reduction of recognition accuracy is a mismatch of the phonetic contexts between the training and testing data. To overcome this problem, we introduce...
Conference Paper
In this paper we report on advances regarding our approach to porting an automatic speech recognition system to a new target task. In cases where there is not enough acoustic data available to allow for thorough estimation of HMM parameters it is impossible to train an appropriate model. The basic idea to overcome this problem is to create a task i...
Conference Paper
The paper describes our successful ongoing approaches toward better recognition accuracy for flexible interactive systems in automatic speech recognition. Degradation in performance of speech recognition systems is observed whenever any current application differs from the conditions during training time. Main speaker independent causes for these d...
Article
Full-text available
With speech recognition systems steadily improving in performance, freedom from head-sets and push-buttons to activate the recognizer is one of the most important issues to achieve user acceptance. Microphone arrays and beamforming can deliver signals that suppress undesired jamming signals but rely on knowledge where the signal is in space. This k...
