Enterprise Interaction Ontology for Change Impact Analysis of Complex Systems

Business Model Design An Evaluation of Paper-based and Computer-Aided Canvases

“…(de Boer et al, 2005), (Kurpjuweit and Aier, 2009), (Kumar et al, 2008)). An exception exists in the work of (Tang et al, 2007) who employ predictive and diagnostic reasoning in BBN.…”

“…However, the definitions are given in an informal and textual manner and no technical realization is supplied. (Kumar et al, 2008) propose rules that encode the dependency relationships of the attributes of entities. Changes are thereby propagated to determine the impact on a defined set of element types, namely business goals, processes, services and infrastructure components as well as the relations runs on, provides, executes and delivers.…”

Supporting Change Propagation in the Evolution of Enterprise Architectures

“…Such relationships are however defined at a high level and it is not clear how they can be used to propagate changes. Another work in this area illustrates how to propagate changes and determine change impacts through rules and ontology [3]. This work does not address any particular EA framework.…”

“…Rather, they require a number of different actions, for example two deletions might be needed, one of the first set and the other for the second set, in the case of removing an entity from a union of two sets. A repair plan's context condition specifies when the plan should be applicable 3 and can be expressed in terms of first-order logic formulaes 4 ). The context condition also contains a predicate Ask(userVal, guidance) indicating that the user should be asked to provide (following the hints provided in the guidance) a value bounded to userVal.…”

“…Unfortunately, there has been very little work on maintenance and evolution of enterprise architectures [2] [3]. Hence, we are in need of techniques and tools that provide more effective automated support for change propagation within an EA model.…”
