Typically, these models are stored in a collection containing several hundreds of process models. In many cases, process models are overlapping, although parts could be easily reused saving costs and efforts. Different labeling styles and evolving process models complicate the detec- tion of reusable model parts. In this paper, we propose a novel approach for the detection of equivalent and similar process model parts that ex- ploits semantic comparison of activity labels and behavioral comparison of control flow. We evaluate our approach on the SAP Reference Model, a collection with 604 process models. The evaluation reveals insights for the thresholds of semantic and behavioral similarity of process models as well as their influence for similar process part detection. Hence, we identify five candidate groups with specific similarity properties that contain reoccurring process parts.

How do they learn what the latest management trends are? The creation and diffusion of management theories and practice is generally viewed as a three stage process: business schools and consulting firms produce the knowledge, the business press disseminates it, and then there is a process of legitimization as these theories become part of ‘common sense’ and form the standard managerial discourse through their representation in non-business media. An ever increasing amount of attention has been paid to the first two of these stages, but relatively little has been paid to how management knowledge might be diffused through other methods. This paper is an attempt to address this gap.

In an age of Bring-Your-Own-Device, small businesses through to globally operating companies increasingly support their employees and customers with SaaS-applications that allow access to internal and external business information. Whether employees are in the office, at a client facility, at home or on the road, they need fast, easy access to business applications with any type of device. SaaS offers companies an interesting alternative to classical on-premise IT solutions. Cloud computing provides innovative applications, high connectivity and performance, cost reduction, flexibility and fast time to market with a minimum of effort. Cloud computing is a special form of outsourcing that has its roots in the fifties. Ten years ago similar concepts to cloud computing e.g. Application Service Providing (ASP) appeared and failed. But it seems that the willingness to use cloud computing is now much higher and the cost pressure effects of the financial crisis also motivate decision makers in companies to focus on cloud computing. This contribution presents the results of actual scientific literature investigations alongside interviews with owners of Software-as-a-Service Marketplaces. It describes several types of SaaS marketplaces using different business models to bring together customers and providers. It shows that SaaS marketplaces are two-sided and demonstrates how platforms are emerging that bundle features into significant value propositions for both sides. This work is relevant to firms who seek business solution recommendations beyond the focus of their on-premise-focussed advisors. It is also relevant for owners and potential owners of SaaS marketplaces and SaaS providers exploring alternatives in their distribution mix.

Ambient Intelligence (AmI) is a vision of an environment that puts the needs of the user in the center of the technological design process. An AmI environment consists of ubiquitous distributed devices such as sensors, displays, data memories which are embedded in everyday objects like walls, clothes, tables or the pavement. These devices are interconnected and seamlessly deliver applications and services to the user. AmI emphasizes the intelligence of the environments interfaces and the intelligence that can be achieved by correlating context information from different data sources. In this work we present an approach to transfer the AmI vision to the public services sector using the paradigm of service orientation and Cloud Computing. Based on scenarios in the healthcare sector the benefits and challenges of such transfer are presented.

However, whereas there is usually an intuitive understanding of this concept, a clear definition has been frequently missing. In this paper, we refine our concept of composability given in. We see composability as a property of an architecture not of systems. In addition, we do not want to reduce composability to the functional specification; rather, we are focusing on how composability effects the nonfunctional properties, especially the composed system's real-time behavior, its reliability, its security, etc. We see the advantage of our approach in having a wide application domain. It works for functional and non-functional properties, it may consider both, hardware and software, and it allows for a description of composition anomalies. In this paper, we show how to apply our concept to an embedded hardware-software co-designed architecture and to composition and decomposition of dependable services in embedded environments.

To address typical design requirements of such systems (e.g., cooperating services, performance and availability) the work proposes a service-oriented architecture (SOA) as architectural concept and architectural translucency to provide stable QoS. We evaluate position sensing systems, QoS assurance approaches and present design principles for service-based health care applications. Furthermore, we present a clinical application scenario and an architectural approach to integrate existing infrastructure into a human centric assistance system.

N2 - For collecting and processing data with AAL infrastructure in the nursing sector, there are legal rules to examine to build a legal framework for the usage of these measured data. Therefore, we consolidated and categorized legal norms presented in the practical orientated nursing literature. Consequently, we identify which data can be defined as worth protecting and which measures of protection are possible for them. On this basis, we present an approach for a legally safe usage of every kind of technical elements within the implementation of AAL infrastructure in the nursing sector.

While the group of elderly workers grows, their sustainment will become more important in future (e.g. Höhn et al. 2008; Dittrich et al. 2011). Especially in combination with an ageing population and a later entrance into the labour market a future shortfall of active workers can be assumed. Germany – as one example of such countries – has only a limited number of options that policy makers and companies can use in the coming decades. One of these is the increased use of the three growing segments in the population: older people, immigrants and an increased participation of women in the labour market. This study focuses the first segment as a potential work force. When promoting that a higher employment rate of older workers can be considered as serious alternative for dealing with the current shortfall of skilled labour force, the motivation of these workers has to be investigated. The works of Alavinia et al. (2007) and Wang, Shultz (2010), which discuss factors influencing the decision to prolong the working age, can be used as starting point. In this context, we analyse the German labour market as an example for a developed country. For the analysis, we use a representative data set of the Federal Institute for Population Research of Germany from published in2008. Here, 1,500 employees (blue collar workers, white collar workers, civil servants) aged between 55 and 64 years were asked about their work situation, motivation and related factors (e.g. further education, job rewards; Büsch et al. 2010). During the data analysis we identify groups of elderly workers using cluster analysis (e.g. Cormack 1971) to develop recommendations for companies. By using existing work motivation and related findings, as well as a representative empirical data set, our study reveals a possibility to identify, classify, and enhance the motivation of workers at the end of their career. This is necessary to keep the quality of goods and service production at an appropriate level. The value of the paper comes from the large number of respondents of the data set and the high relevance of the German situation for other developed countries. At the end, powerful recommendations for companies how to involve and motivate elderly workers for longer periods of employment can be derived.

In this context two different models and expert surveys are used in this study to evaluate the readiness level of the city of Medellin to adopt smart grid technologies. The results of this study show that the City has the utilities, the knowledge, the universities and the human resource to become a role model in the region. But an effort to integrate all the actors and impulse a common agenda is required. The utility companies need to lead this development, but regulators, academia and industry must back up this endeavor and enable Medellin to lead the power grid development of the next years in the region.

Without innovation and the closely linked subject of creativity, companies would not develop further and could not succeed within the globalized world. A crucial factor of innovation and creativity are people. Employees need to have the possibility to be creative because without creative minds no new ideas are generated and therefore no innovation takes place. The aim of the paper is to give an overview about the linkage between creativity and innovation. Additionally the theoretical advancement describes the importance of employee motivation for organizational innovation. The results show the necessity of creative work force within an innovative organization since creativity and innovation are closely related to each other. Employee motivation plays a key role for creativity hence a positively stimulating corporate culture is needed in order to have an innovative company.

As a response healthcare institutions are relying in the implementation of Information and communication technologies (ICTs) to overcome difficulties and satisfy patients’ demands in a cost-effective way adopting new technologies capable to innovate, extend, and redefine the way healthcare has been delivered for decades. New technological innovations such as Internet of things (IoT), Smart item technology, and cloud computing can improve the traditional e-healthcare system and extend service provision beyond the hospital facilities by using wireless sensor networks (WSN) and radio frequency identification devices (RFID), providing a new type of services advertised as “smart.” This type of services, enable doctors to treat patients remotely and allows people to do their normal daily routines, occupations, and activities while receiving appropriate, timely, and high-quality ubiquitous healthcare services. Methods: An exploratory study is performed to review the route towards smart healthcare services, emphasizing the use of information and communication technologies (ICTs) and smart item technology as enhancers for smart healthcare services provision. Results/findings: A new technological infrastructure promises to transform medical practice and disease prevention by empowering healthcare institutions with smart items for remote patient monitoring eliminating time-wasting procedures, reducing health costs, improving quality of service and patients satisfaction. Implications/conclusions: Traditional e-healthcare system is transitioning into an interconnected smart-healthcare system potentiated by new technological advances capable to extend healthcare service provision and offer smart healthcare services.

T1 - Strategies to reduce information asymmetry in Web Service Market T2 - Proceedings of the Eleventh European Conference on Information Systems N2 - The web service model provides fundamental advantages compared to the classical software usage model. But transactions in the web service market have by far not reached the expected level. A reason for the tendency of market failure is the verifiable information asymmetry and uncertainty in the web service market. Besides deficiencies on the supply side, regarding configuration, display and communication of web service bundles, the limited web service knowledge of potential buyers are constitutional causes to the modest development and enforcement of the web service model. By the help of strategies derived from information economics the present study elaborates measures to take in order to prevent the market for web based services from failing. The conclusions of an online-based questioning experiment offer strategic recommendations to reduce buyer’s uncertainty in outsourcing decision. Results of the experiment point out the significant positive impact to reduce information asymmetry and transaction uncertainty in the web service market by integrating information substitutes in the web service bundle in order to transform experience and credence qualities into search qualities. It can be verified that web service customers have a higher willingness to pay when information substitutes are integrated into the web service bundle.

At this point, it is still unclear why and when customers prefer the ASP model over more traditional approaches. To make ASP more attractive, more knowledge about possible pricing and product strategies is needed. In this paper we describe different business models for ASP marketplaces. We first compare the cost structures of the classical licensing model with the new server-based approach. Then we illustrate how price and product differentiation may improve overall market efficiency. In particular, we show that by selling different software versions for different prices, ASP marketplaces may obtain near-optimal revenues with products that are relatively inexpensive, disaggregated, and customizable. Consumers can thus choose between a wide variety of product lines to fit their differing budgets and requirements.

We present an approach, which allows optimizing the service delivery through continual process improvement. This approach combines the 7-step improvement process recommended by ITIL with process mining. On the basis of suggestions derived from process mining, performance indicators of different services are determined and subsequently compared as part of an internal benchmark. The approach, which will be trialed in practice, enables the optimization of service delivery certainly, but it is also concerned with the most effective utilization of limited resources in terms of people and tools.
