Process management in hospitals: an empirically grounded maturity model

2014-10-01 , Cleven, Anne , Winter, Robert , Wortmann, Felix , Mettler, Tobias

In order to improve transparency and stabilise health care costs, several countries have decided to reform their healthcare system on the basis of diagnosis related groups (DRG). DRG systems induce active competition among hospitals, forcing them to become more efficient and effective. In consequence, hospitals are investing considerably in process orientation and management. However, to date there is neither a consensus on what capabilities hospitals need to acquire for becoming process-oriented, nor a general agreement on the sequence of development stages they have to traverse. To this end, this study proposes a theoretically grounded conceptualisation of process management capabilities and presents a staged maturity model algorithmically derived on the basis of empirical data from 129 acute somatic hospitals in Switzerland. The five maturity levels start with ‘encouragement of process orientation' (level 1), ‘case-by-case handling' (level 2), and ‘defined processes' (level 3). Ultimately, hospitals can reach the levels ‘occasional corrective action' (level 4) and ‘closed loop improvement' (level 5). The empirically derived model reveals why available maturity models for process management are not applicable in the hospitals context: Their comparatively high complexity on the one hand and their strong focus on topics like an adequate IT integration and process automation on the other make them inadequate for solving the problems felt in the hospital sector, which are primarily cultural and structural.

Vorgehensmodelle für die rollenbasierte Autorisierung in heterogenen Systemlandschaften

2007-12 , Wortmann, Felix , Winter, Robert

The authors examine how an authorization architecture can be defined which spans various information systems and organizational units. After introducing authorization and architecture fundamentals, related work on authorization, architecture management and role definition is discussed. In particular regarding procedure models for authorization architecture design, these approaches are not very detailed. Moreover they are neither theoretically well-founded nor transparently derived from current industry practices. Therefore two actual industry practices are presented as case studies. By consolidating these practices with findings from current research, a starting point for an improved procedure model for authorization is proposed.

Process Performance Management - A Systematic Problem Analysis and Identification of Design Principles

2012-10-01 , Cleven, Anne , Winter, Robert , Wortmann, Felix

Business processes are the means by which organisations create value. Consequently, organisations need to continuously monitor and control their processes' performance so as to provide a consistent and predictable execution quality. A number of today's organisations, however, appear to encounter difficulties with measuring and improving their processes' performance. In this paper, we set out to identify the gap between how organisations currently approach process performance management (PPM) and what they are striving to realise in the future. The systematic gap analysis results in a set of design factors that are valuable in guiding future design efforts for useful and relevant PPM solutions.

Towards Private-Public Research Partnerships Combining Rigor and Relevance in DWH/BI Research: The Competence Center Approach

2010 , Cleven, Anne , Winter, Robert , Wortmann, Felix

Business intelligence (BI) and data warehousing (DWH) research represent two increasingly popular, but still emerging fields in the information systems (IS) academic discipline. As such, they raise two substantial questions: Firstly, how rigorous, i.e., fundamental, constituent, and explanatory, is DWH/ BI research? and, secondly, how relevant, i.e., useful and purposeful, is this research to practitioners? In this article, the authors uphold the position that relevance and rigor are by no means dichotomous, but two sides of the same coin. Naturally, this requires well-defined approaches and guidelines-for scholarship in general and DWH/BI research in particular. Therefore, this paper proposes the competence center (CC) approach-a private-public partnership between academia and practice. The authors illustrate how the CC approach can be applied within the field of DWH/BI and suggest that a close link between research and practice supports both enhancing relevance to practice and strengthening rigor of research.

Success Factors of Application Integration: An Exploratory Analysis

2010-11-01 , Gericke, Anke , Klesse, Mario , Winter, Robert , Wortmann, Felix

The increased deployment of commercial off-the-shelf (COTS) applications creates application integration challenges. However, very few articles focus on application integration success. That is why we first analyze these contributions and derive success factor candidates (SFCs). In addition, contributions dealing with problems and risks of application integration and related research fields are examined-as they allow for the derivation of further SFCs. In total twenty-six SFCs are collected. A factor analysis is conducted to examine interrelations between SFCs. It yields seven success factor groups, e.g., architecture management, IT/business alignment, or use of methods. In a second step, an exploratory analysis is conducted to examine the impact of these SFCs on various success indicators of application integration. These success indicators were defined beforehand by analyzing theories for information system (IS) success. As a result of the exploratory analysis, twenty-seven hypotheses are proposed. These hypotheses need to be corroborated in a future confirmatory study.
