In this paper, we explore the fundamentals of EA information modeling, namely the meta-languages underlying today’s models, ArchiMates limitations in modeling precisely use cases is a well known fact. ResearchGate has not been able to resolve any references for this publication. Largely disconnected, different methods for documenting and planning the EA and her evolution have been discussed, leading to object-oriented models for this purpose – the so called information models. Business and IT Designers at all levels who need to design solution building blocks (SBBs) and must work within defined architectures. By using a case-based analysis we sketch extension points for a digital enterprise ecosystem modeling method based on ArchiMate. of applications with other applications and with business processes however makes it difficult to get a complete view on change To do so, we discuss the requirements for a suitable object-oriented meta model and exemplify the requirements with an extension to the OMG's Meta Object Facility. ... [27] Similar to the multitude of existing approaches regarding analysis techniques as alluded to above, a plurality of corresponding meta models (cf. The methodology relies on capturing user requirements in a Reference Model and finding acceptable compromises of IT development, to reach the alignment incrementally. Banks learned that these innovations require close integration with the existing channels, processes and systems in the front as well as in the backend. proposed for the context of EA management provide only limited support for modelling qualitative and quantitative dependencies. Based on the results of this classification, future areas of research regarding EA analysis are derived. In this paper we present a classification schema for EA analysis approaches to examine this topic. The domains of EA are linked and interrelated, ... ArchiMate with its business layer, application layer and technology layer seems to be an appropriate modeling method for describing such digital ecosystems. Nevertheless, the approaches presented stay either on a level too abstract to provide realization support or are far too general neglecting organization-specific EA related goals, concerns, and contexts. This paper charts a philosophical route through a discussion on models and what they represent, the communication structures implicitly required for models to work and proposes that model based simulation of a model based enterprise can be more effective if there is a theoretical basis to a simulation model. Enterprise architecture (EA) management has not only recently gained importance as means to support enterprises in adapting An Enterprise resource planning system is a fully integrated business management system covering functional areas of an enterprise like Logistics, Production, Finance, Accounting and Human Resources. Thus, the objective of this study was to develop a framework, which can be used to examine and understand how various events and factors manifest in their natural settings to cause complexities, during development and implementation of EA in organizations. to a changing market environment and in seizing new business opportunities. This trend also affects the underlying IT architecture which has to integrate and provide software components (e.g. accounts for the requirements of EA analysis. of research – a meta-language for EA information modeling. Business and information system alignment is key to improve business performance. as-is states of the architecture as well as assessing planned future states. Building on the standard of the OMG, we present an extension of MOF designed to support This paper demonstrates that the analysis of fiscal sustainability of social security must include an additional dimension of, We model PAYG social security systems as the outcome of majority voting within a OLG model with production. Introduction to the Course "The Practice of Enterprise Architecture". Controlling such changes cannot be done by just ‘winging it’. In the paper at hand, we show that existing enterprise modeling approaches are inappropriate for modeling digital enterprise ecosystems comprehensively. In this paper we present a strategy to solve this problem by separating the ontological and the linguistic aspects of a metamodel and a metamodeling framework. Our analysis uncovers two reason for this. We demonstrate that while the FF system results in relatively higher rates of physical capital accumulation, then under some conditions, other things equal, the PAYG social security regime leads to the choice of relatively higher respective levels of education tax rates in all generations, and thereby to higher rates of human capital accumulation.

This study aimed to develop such an inventory. This paper proposes a methodology for accompanying the evolution of factory information and control systems for complex enterprises in an agile environment, from a functional standpoint. Although it is well known that modelling business processes can be challenging for organisations, an inventory of known issues, which could be of use to organisations to plan and manage BPM projects, is missing. Numerous information technology (IT)-based innovations from automated teller machines to electronic banking have already changed the customer-bank-interaction. In this article, we,discuss the architecture framework,of The Open,Group (TOGAF) and,detail on its promising,but nevertheless highly generic architecture development,method,(ADM). A representative individual lives for two periods; works when young and depends on savings and a government operated social security system when old—the returns on both sources of income, when old, are random. Based on the analysis, we elicit requirements for a “unifying” meta-language. Under general circumstances, there exist equilibria where pensions are voted into existence and maintained. © 2008-2020 ResearchGate GmbH. Despite the variety of the comprehensive IT business alignment frameworks available, many enterprises struggle with the implementation because of the excessive resource requirements and the high complexity processes. This article shows how,the generic development,steps can be complemented by a pattern,based,approach,to EA management,providing guidance,for addressing specific EA related concerns,with step- by-step methodologies,as well as with corresponding,viewpoints and information,models. Managing the evolution of the Enterprise Architecture (EA) is a key challenge for modern enterprises. impacts and dependency structures. EA is considered as a key "tool" to support enterprise engineering by helping stakeholders to manage changes at all levels: Strategic, organizational, and IT issues (Chen et al., 2008b; ... We consider the following definition of EA: "a coherent whole of principles, methods, and models that are used in the design and realisation of an enterprise's organisational structure, business processes, information systems, and infrastructure", ... [20]). Complementing, we further introduce a conceptual model, which explicates the information demands for such roadmap plans. The approach allows all aspects of the architecture to be precisely defined using standard modelling notations. Economic business models for organisations have led to outsourced services as an attractive way of reducing costs and allowing a business to focus on its key processes. As a result, we theorize the permeability of community boundaries around architects as key to the success of EAI: When architects prioritize what they think is important over the views and concerns of business and technology stakeholders community, a dominant intra‐CoP perspective will emerge, and boundaries around the community of architects will be reinforced, preventing stakeholders with legitimate interests in the EAI to influence the process; in contrast, when architects prioritize engaging with the viewpoints and concerns of business and technology stakeholders community, boundaries will become permeable, and an intercommunity CoP will emerge, enabling knowledge sharing and negotiations between everyone with legitimate interests in the EAI.
