Federated Embedded Systems – a review of the literature in related fields

This report is concerned with the vision of smart interconnected objects, a vision that has attracted much attention lately. In this paper, embedded, interconnected, open, and heterogeneous control systems are in focus, formally referred to as Federated Embedded Systems. To place FES into a context, a review of some related research directions is presented. This review includes such concepts as systems of systems, cyber-physical systems, ubiquitous computing, internet of things, and multi-agent systems. Interestingly, the reviewed fields seem to overlap with each other in an increasing number of ways

Management and architecture click: The FAD(E)E Framework.

Enterprises are living things. They constantly need to be (re-)architected in order to achieve the necessary agility, alignment and integration. This paper gives a high-level overview of how companies can go about doing 'enterprise architecture' in the context of both the classic (isolated) enterprise and the Extended Enterprise. By discussing the goals that are pursued in an enterprise architecture effort we reveal some basic requirements that can be put on the process of architecting the enterprise. The relationship between managing and architecting the enterprise is discussed and clarified in the FAD(E)E, the Framework for the Architectural Development of the (Extended) Enterprise.Management; Architecture; Framework;

System Evolution Barriers and How to Overcome Them!

Creating complex systems from scratch is time consuming and costly, therefore a strategy often chosen by companies is to evolve existing systems. Yet evolving a system is also complicated. Complex systems are usually the result of multidisciplinary teams, therefore it is essential to understand barriers those teams face when evolving a system.\ud From the research carried at Philips Healthcare MRI, we have identified that main evolution barriers employees face are; managing system complexity,communication across disciplines and departments, finding the necessary system information, lack of system overview, and ineffective knowledge sharing. Those barriers were identified as the root cause of many development problems and bad decisions.\ud To overcome those barriers, and therefore enhance the evolution process, effective reuse of knowledge is essential. This knowledge must be presented in a fashion that can be understood by a broad set of stakeholders. In this paper system evolution barriers and a method to effectively deal with them, based on the creation of A3 Architecture Overviews, is presented

Critical Issues in Enterprise Architecting – A Literature Review

Enterprise Architecture (EA) has been identified as a means to Business-/IT-Alignment, cost reduction or to facilitate change. Research has been focusing on the effectiveness of EA management while the enterprise architecting process is the process of developing, managing, utilizing and maintaining architectural descriptions (ADs) for EA. In this paper we present the results of a literature review on the process of enterprise architecting. Our research contribution is a consolidated view on the challenges and issues arising throughout the architecting process

Enterprise Architecture Modeling, Design and Transformation: Defining the Missing Links

Outline - • Propose a unifying conceptual framework guiding the “front-end” of planned enterprise change (transformation) management process • Enterprise architecture design process (enterprise architecting) • Choice of enterprise architecture for emphasis • Enterprise architecture modeling strategies • Transition moves available for enterprise transformation • Show how the framework links together a number of the key design decisions that need to be considered simultaneously, under alternative combinations of major contingency condition
