How German hospitals govern IT - An empirical exploration

Health care services in German hospitals are causing immense expenses. Successful IT Governance might help to support specific challenges for every organization with an adequate use of IT. The market structure of hospitals in Germany is very heterogeneous, e.g. in size and sponsorship. This paper analyses the state of the art of IT Governance based on a survey among 220 IT executives in German hospitals. The quantitative analyses of collected survey data reveal that hospitals govern their IT differently according to size and sponsorship. In addition, our analyses show that decision-making authority for the IT budget rises with hospital size and is positively correlated with the fraction of IT projects in the overall IT budget. We also show that the investments in innovative IT projects increase with hospital size. Our study revealed that a high number of private and larger hospitals lack a systematic IT Governance approach within the decision domain on IT projects. This study is the first to shed light into the empirical situation of IT Governance in German hospitals. Creativity-intensive processes such as the development of marketing campaigns or the production of visual effects increasingly find their way into the agenda of process managers. Such processes often comprise of both well-structured, transactional parts and creative parts that often cannot be specified in terms of their process flow, required resources, and outcome. Moreover, the processes’ high variability sets boundaries for the possible degree of automation. In this paper we introduce the concept of pockets of creativity as an analytic device which is hoped to support process managers in their efforts to identify and describe creative sections in business processes. We argue that this step of identifying and describing is imperative to successfully allocate resources, integrate creativity into the overall process, and introduce process automation for those parts that are well-structured and can actually be automated. Our argument rests in the examination of existent literature as well as in findings from exploratory case studies that were conducted in the film and visual effects industry in order to study processes that rely on creativity

A Time Projection Chamber with GEM-Based Readout

For the International Large Detector concept at the planned International Linear Collider, the use of time projection chambers (TPC) with micro-pattern gas detector readout as the main tracking detector is investigated. In this paper, results from a prototype TPC, placed in a 1 T solenoidal field and read out with three independent GEM-based readout modules, are reported. The TPC was exposed to a 6 GeV electron beam at the DESY II synchrotron. The efficiency for reconstructing hits, the measurement of the drift velocity, the space point resolution and the control of field inhomogeneities are presented.Comment: 22 pages, 19 figure

A conceptual framework for information retrieval to support creativity in business processes

Creativity as the prerequisite for innovation is a core competitive factor in contemporary organizations. When creativity happens this involves creative persons who produce creative products in a process that cannot be fully anticipated and predescribed. We introduce the concept of pockets of creativity for those sections of a business process where creativity occurs. These sections are characterized by a high demand for flexibility and knowledge of the involved creative persons. In pockets of creativity previous knowledge is retrieved, transformed and combined into new procedures or artifacts – in short – innovations. Naturally, this raises the question of how pockets of creativity can be supported by information technology. Information retrieval is part of an organizations knowledge processes concerned with the representation, storage, organization, searching and finding of organizational knowledge. Informed by case studies we have conducted with organizations from the Creative Industries and drawing from existing theory, in this paper we introduce a conceptual framework for information retrieval that enables creative persons to access relevant information through a multi-perspective, hierarchical view. Such an approach both appropriately considers different ways of creative thinking and provides stimuli to a person's cognitive network fostering her creativity and thus the development of truly innovative products

Pockets of creativity in business processes

Creative processes, for instance, the development of visual effects or computer games, increasingly become part of the agenda of information systems researchers and practitioners. Such processes get their managerial challenges from the fact that they comprise both well-structured, transactional parts and creative parts. The latter can often not be precisely specified in terms of control flow, required resources, and outcome. The processes’ high uncertainty sets boundaries for the application of traditional business process management concepts, such as process automation, process modeling, process performance measurement, and risk management. Organizations must thus exercise caution when it comes to managing creative processes and supporting these with information technology. This, in turn, requires a profound understanding of the concept of creativity in business processes. In response to this, the present paper introduces a framework for conceptualizing creativity within business processes. The conceptual framework describes three types of uncertainty and constraints as well as the interrelationships among these. The study is grounded in the findings from three case studies that were conducted in the film and visual effects industry. Moreover, we provide initial evidence for the framework’s validity beyond this narrow focus. The framework is intended to serve as a sensitizing device that can guide further information systems research on creativity-related phenomena
