Business process improvement can drastically influence in the profit of corporations and helps them to remain viable. However, the use of traditional Business Intelligence systems is not sufficient to meet today's business needs. They normally are business domain-specific and have not been sufficiently process-aware to support the needs of process improvement-type activities, especially on large and complex supply chains, where it entails integrating, monitoring and analysing a vast amount of dispersed event logs, with no structure, and produced on a variety of heterogeneous environments. This paper tackles this variability by devising different Big Data based approaches that aim to gain visibility into process performance.

We further propose that this individual-level reaction to the faultline structure of the team can differ among team members, depending on the size of their subgroup and on their individual social competence. We tested the assumptions with a sample of real teams working on an intellective task during which social loafing behaviour was video-coded. In partial support of the hypotheses, generalized mixed models revealed that social loafing behaviour was most common for team members who were part of a team with strong faultlines, who belonged to the larger subgroup in their team, and who exhibited low levels of social competence. The results therefore highlight the benefits of taking a multilevel approach to the effects of faultlines.

T1 - Put-Down Humor Directed at Outgroup Members Increases Perceived - But Not Experienced - Cohesion in Groups JF - Humor: International Journal of Humor Research N2 - Put-down humor always has a target, and the intent of the speaker is to make fun of someone or something. Due to its inherently social nature, put-down humor could strongly affect socio-emotional group processes and outcomes like cohesion. We hypothesized that put-down humor would increase cohesion when it was targeted at outgroup members and was followed by laughter. Two laboratory experiments were conducted to examine the underlying processes of the put-down humor – cohesion relation. Study 1 showed that put-down humor of outgroup members (as compared to no humor) did not increase participants’ attraction to the group. But it increased perceived cohesion among other group members and the perception that other group members felt safer and were more similar to each other. Even when procedures were altered in Study 2 to reduce participants’ evaluation apprehension and their potential anxiety about not themselves being humorous, we found the same pattern of results. We discuss which conditions might be necessary for put-down humor to increase one’s personal attraction to a group.

Thus, it tends to encounter limits when attempting to achieve objectives lying beyond the contract. In contrast, the concept of contractual management presented here is based on the possible contributions of the contract to the management of the enterprise, business unit, and transaction. It considers the processes relevant in this field which are bundled by risk management, transaction management, and knowledge management. Insofar as it integrates these activities and aligns them towards the contract, it increases the potential impact of the contract. From the governance perspective, contractual management leads to higher efficiency; from a legal perspective, it provides for a better compliance with the requirements for good corporate management and with contractual obligations as well as it increases the quality of the contract.

Using data from the nationally representative ‘Survey on continuing in employment in pensionable age’, we investigate the relevance of training motivation for work ability and the desire to work past retirement age and whether differences between social groups reflect inequalities in training participation. Results show significant positive correlations between continuing training motivation and work ability and desire to work past retirement age. Differentiated for selected respondent groups the level of qualification has a significant influence. This effect was stronger than any differences with regard to gender or employment participation. Results imply external conditions only partly explain older workers’ work ability or desire to work past retirement age. Compared to inequalities in training participation, motivation for continuing training is high across analysed subgroups.

As the German retirement pay system is a pay-as-you-go system, legal retirement age is increased step by step to 67 years. Long before individuals actually retire, environmental factors but also personal factors influence the path of the retirement process. Work ability can be maintained through continuing education. Understanding and possibly even increasing older employees’ motivation to participate in continuing education is vital to achieving the European Union’s aim of individuals’ “lifelong learning” to cope with challenges of technological and organisational change. This empirical study analyses the influence of work context factors on motivation to participate in continuing education. Data source is the “Survey on continuing in employment after reaching pensionable age”, commissioned in 2008 by the Bundesinstitut für Bevölkerungsforschung (Federal Institute for Population Research). Results show weak but significant influences of some work context factors. Recommendations for actions and further research directions are given.

T1 - Negative effects of coaching for coaches: an explorative study JF - International Coaching Psychology Review N2 - There exists only scarce knowledge regarding what negative effects can occur to business coaches as a result of their work. Negative effects, defined as all harmful or unwanted results for coaches directly caused by coaching that occur parallel to or following coaching, are theoretically inferred in this study. Additionally, negative effects are quantitatively explored and validated. Negative effects of coaching for coaches were identified via structured expert interviews. Based on the results of the interviews a new questionnaire was developed. Coaches were then surveyed online using this questionnaire. A sample of supervisors was also surveyed and compared to the coaches regarding important work-related variables. 104 German coaches were quantitively surveyed using a new questionnaire regarding the frequency and intensity of negative effects in their most recent coaching and in their career. To validate the new questionnaire and the results, relevant cognitions towards their work (psychological empowerment) and the affective well-being of the coaches were also measured. In more than 90 per cent of all recent coaching at least one negative effect was present. On average 5.9 negative effects occurred per coaching. During their careers 99 per cent of the coaches were confronted at least once with a negative effect. Negative effects are associated with the psychological empowerment and affective well-being of coaches, which speaks for the validity of the new questionnaire and subsequent results. Negative effects for coaches as a result of their work occur very often and in a heterogeneous way but these effects are of rather low intensity. The validity of these effects could be shown.

An effective defence against crises is only possible if the organizational resilience and the capacity to handle crises become part of the hospitals’ organizational culture. To become more resilient to crises, a raised awareness — especially in the area of human resource (HR) — is necessary. The aim of this paper is to contribute to the process robustness against crises through the identification and evaluation of relevant HR crises and their causations in hospitals. Qualitative and quantitative methods were combined to identify and evaluate crises in hospitals in the HR sector. A structured workshop with experts was conducted to identify HR crises and their descriptions, as well as causes and consequences for patients and hospitals. To evaluate the findings, an online survey was carried out to rate the occurrence (past, future) and dangerousness of each crisis. Six HR crises were identified in this study: staff shortages, acute loss of personnel following a pandemic, damage to reputation, insufficient communication during restructuring, bullying, and misuse of drugs. The highest occurrence probability in the future was seen in staff shortages, followed by acute loss of personnel following a pandemic. Staff shortages, damage to reputation, and acute loss of personnel following a pandemic were seen as the most dangerous crises. The study concludes that coping with HR crises in hospitals is existential for hospitals and requires increased awareness. The six HR crises identified occurred regularly in German hospitals in the past, and their occurrence probability for the future was rated as high.

Currently, both job seekers and talent hunters are looking for new and innovative techniques to filter jobs and candidates where candidates are trying to improve and make their profiles more attractive. In this sense, the Skillrank approach is based on the conjunction of existing and well-known information and expertise retrieval techniques that perfectly fit the existing web and social media environment to deliver an intelligent component to integrate the user context in the analysis of skills confidence. A major outcome of this approach is that it actually takes advantage of existing data and information available on the web to perform both a ranked list of experts in a field and a confidence value for every professional skill. Thus, expertise and experts can be detected, verified, and ranked using a suited trust metric. An experiment to validate the Skillrank technique based on precision and recall metrics is also presented using two different datasets: (1) ad hoc created using real data from a professional social network and (2) real data extracted from the LinkedIn API.

This is exemplified by an application scenario in healthcare that was developed in the context of the OpSIT-Project in Germany. We present a three-level architecture for a smart healthcare infrastructure. The approach is based on a service-oriented architecture and extends established architectural approaches developed previously at our group. More specifically, it integrates a role model, a layered cloud computing architecture, as well as a fog-computing-informed paradigm in order to provide a viable architecture for healthcare and elderly-care applications. The integration of established paradigms is beneficial with respect to providing adequate quality of service and governance (e.g., data privacy and compliance). It has been verified by expert interviews with healthcare specialists and IT professionals. To further demonstrate the validity of this architectural model, we provide an example use-case as a template for any kind of smart sensor-based healthcare infrastructure.

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.

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.

Access, affordability and quality to proper healthcare is a great challenge in world society. With the utilization of smart sensors, there are possibilities to improve the quality of healthcare services whenever needed. Hence, such smart items services lead to economic advantages for the whole healthcare system. Keeping in mind these opportunities as well as challenges such as security or legal issues, it is important to bring healthcare and IT together. As a result, healthcare business processes need to be modeled in order to provide IT solutions tailored for practice-oriented applications. In this paper, we present a three-level architecture for a smart healthcare infrastructure. Our approach is based on recent literature work and results from conducted expert interviews with healthcare specialists and IT professionals. To demonstrate the applicability of this architecture model, we provide an example use-case as a template for any kind of smart sensor-based healthcare infrastructure.

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.

We found out, that most of the participants think, that they know too little about the corporate social responsibility activities of their company, evaluate the atmosphere as not really good and don’t see their own responsibility. Also they mentioned, that the employees mostly talk with each other about emotions and stories, less about facts and information. In the discussion all agreed, that it would be much more effective, if information about social responsibility is delivered by stories—by storytelling. We prove this by a questionnaire, where we give the participants the same information about employees social and corporate social activities in a short news with numbers and also in the form of storytelling. We ask them, which text they would tell their friends, neighbours or colleagues and which text would attract them at most to motivate themselves for acting more responsible. We also ask the employees how they think this could be realised. With the result we can show, how you can sensitize and activate people for bringing more attention, awareness and activity to a more responsible living inside and outside companies.

ER - TY - CHAP A1 - Ternès, Anabel T1 - Sustainable Customer Service as Success Factor in the Airline Sector T2 - 1st International Civil Aviation Symposium (ICAS), Cairo N2 - A high number of airlines has been switching its business concept from fixed prices for economy or business class to a system of bundles, where customers can choose among a different set of services and book flights to different prices, depending on their individual preferences. This paper aims at finding out which services are those consumers regard as most important and what therefore makes an airline a sustainable choice in terms of service. For that purpose a survey has been conducted for approx. one week, where participants have answered a set of questions online and offline. In the second chapter, the authors will explain certain ground assumptions of online consumers, stressing the importance of user-friendly websites as well as the cost of the most popular extra services offered by regular airlines and also low-cost carriers. Keeping this in mind, the survey’s results will be presented in chapter four. 105 participants gave their opinion on what makes an airline’s service sustainable to them, the result being a mixture of good cabin crew soft skills, a minimum degree of comfort and efficiency throughout the whole time of purchasing a flight, being on board and leaving the aircraft. A user-friendly booking procedure as well as being able of leaving the airplane fast and receiving its luggage without further waiting has - according to the survey - won over seats in the front row, high-quality menus and entertainment programs. Even the sustainability aspect having been regarded as a factor of high-quality services, is not a major criterion for travelers. What in most cases makes an airline sustainable for passengers is friendly personnel. The bundle systems are preferred, since the cabin crew aspect has not vanished completely in the airline sector, even among low budget airlines. To receive transparency and flexibility when booking a flight, saving money but knowing that a certain quality will almost always be delivered through soft skills on board could be the reason why passengers feel more comfortable with the new business concepts.

Internationale Tagung Wirtschaftsinformatik, Bamberg N2 - Die Umsetzung von IT-Service-Support-Prozessen auf der Basis des Referenzmodells IT Infrastructure Library (ITIL) geschieht in vielen Unternehmen derzeit mit hoher Priorität. Obwohl zur Unterstützung der Support-Prozesse eine Vielzahl von Softwarelösungen zur Verfügung stehen, basieren diese heute nicht auf Service-orientierten-Architekturen. Die Vorteile einer Service-orientierten-Architektur werden daher im Rahmen des IT-Service-Supports nicht genutzt. Der Beitrag zeigt am Beispiel eines zentralen ITIL-Support-Prozesses, dem Incident-Management, wie dieser technisch auf der Basis von Web-Services umgesetzt werden kann. Die Grundlage bilden sechs Fallstudien, in denen die Gestaltung ITIL-basierter Support-Prozesse untersucht wurde. Aufbauend auf den Fallstudien wird ein generischer Incident-Management-Prozess definiert und mit Hilfe von Web-Services umgesetzt. Dabei kommen sowohl atomare als auch aggregierte Web-Services zum Einsatz. Für ein konkretes Service-Anliegen wird der Prozessablauf grafisch beschrieben. Die Umsetzung erfolgt exemplarisch unter Zuhilfenahme der Web Services Description Language (WSDL).
