Assessing the integration of information system components
Management of health information systems

Abstract (Expand)

This paper presents formal approaches for assessing the integration of information system components. They were developed to support decisions in the strategic management of information systems. The … fulfillment of integration requirements, the dependency of information system components on each other, and the heterogeneity of the integration infrastructure are the major assessment criteria.The meta-model 3LGM2A is the (semi-)formal base for methods introduced here. The fulfillment of integration requirements is checked by matching sets of application components that have specific requirements (requirements domains) with sets of application components that exchange data or call operations related to the requirements (communication domains). Requirements categories support the handling of the numerous specific requirements.For assessing the complexity of an information system or its subsystems the figures degree of informational dependence, degree of functional dependence, and degree of heterogeneity are defined.

3LGM(2)-Modelling to Support Management of Health Information Systems
Management of health information systems

Abstract (Expand)

Both regional health information systems and hospital information systems need systematic information management. Due to their complexity information management needs a thorough description or model … of the managed HIS. The three layer graph based meta model (3LGM(2)) and the 3LGM(2) tool provide means for effectively modeling HIS. The 3LGM(2) tool has been used to build a model of the health information system of the German federal state Saxony. The model is not only used to support the further development of the Saxonian health information system but also for supporting strategic information management planning in the medical center of Leipzig University. Acceptance of the method depends strictly on its integration in management structures on the institutional, regional, national or even European level.

Preparing strategic information management plans for hospitals: a practical guideline: SIM plans for hospitals: a guideline
Management of health information systems

Abstract (Expand)

OBJECTIVES:: Systematic information management in hospitals demands for a strategic information management plan (SIM plan). As preparing a SIM plan is a considerable challenge we provide a practical … guideline that is directly applicable when a SIM plan is going to be prepared. METHODS:: The guideline recommends a detailed structure of a SIM plan and gives advices about its content and the preparation process. It may be used as template, which can be adapted to the individual demands of any hospital. RESULTS:: The guideline was used in several hospitals preparing a SIM plan. Experiences showed that the SIM plans could be prepared very efficiently and timely using the guideline, that the proposed SIM plan structure suited well, that the guideline offers enough flexibility to meet the requirements of the individual hospitals and that the specific recommendations of the guideline were very helpful. CONCLUSIONS:: Nevertheless, we must strive for a more comprehensive theory of strategic information management planning which - in the sense of enterprise architecture planning - represents the intrinsic correlations of the different parts of a SIM plan to a greater extent.
