Konferensbidrag (refereegranskat)abstract
- Enterprise Architecture (EA) management is a commonly accepted instrument to support strategic decision making. The objective of EA management is to improve business IT alignment by making the impact of planned changes explicit. The increasing interconnectivity of applications with other applications and with business processes however makes it difficult to get a complete view on change impacts and dependency structures. This information is nevertheless required to support decision makers. Current meta-languages proposed for the context of EA management provide only limited support for modelling qualitative and quantitative dependencies. In this paper we propose a meta-language, which builds on the Meta Object Facility (MOF). This meta-language specifically accounts for the requirements of EA analysis. We discuss existing meta-languages from the field of EA management and related areas against these requirements. Building on the standard of the OMG, we present an extension of MOF designed to support EA analysis. The theoretic exposition of the extension is complemented by an example illustrating the applicability of the presented meta-language.

A tool for automatic enterprise architecture modeling
- 2011
-
Ingår i: Proceedings of the CAiSE Forum 2011. ; , s. 25-32
-
Konferensbidrag (refereegranskat)abstract
- Enterprise architecture is an approach which aim to provide decision support based on organization-wide models. The creation of these models is however cumbersome as multiple aspects of an organization need to be considered. The Enterprise Architecture approach would be significantly less demanding if data used to create the models could be collected automatically. This paper illustrates how a vulnerability scanner can be utilized for data collection in order to automatically create enterprise architecture models. We show how this approach can be realized by extending an earlier presented Enterprise Architecture tool. An example is provided through a case study applying the tool on a real network.

A tool for enterprise architecture analysis using the PRM formalism
- 2010
-
Ingår i: CEUR Workshop Proceedings.
-
Konferensbidrag (refereegranskat)abstract
- Enterprise architecture advocates model-based decision-making on enterprise-wide information system issues. In order to provide decisionmaking support, enterprise architecture models should not only be descriptive but also enable analysis. This paper presents a software tool, currently under development, for the evaluation of enterprise architecture models. In particular, the paper focuses on how to encode scientific theories so that they can be used for model-based analysis and reasoning under uncertainty. The tool architecture is described, and a case study shows how the tool supports the process of enterprise architecture analysis.

Automating enterprise architecture documentation using an enterprise service bus
- 2012
-
Ingår i: 18th Americas Conference on Information Systems 2012, AMCIS 2012. ; , s. 4213-4226
-
Konferensbidrag (refereegranskat)abstract
- Currently the documentation of Enterprise Architectures (EA) requires manual collection of data resulting in an error prone, expensive, and time consuming process. Recent approaches seek to automate and improve EA documentation by employing the productive system environment of organizations. In this paper, we investigate a specific Enterprise Service Bus (ESB) considered as the nervous system of an enterprise interconnecting business applications and processes as an information source. We evaluate the degree of coverage to which data of a productive system can be used for EA documentation. A vendor-specific ESB data model is reverse-engineered and transformation rules for three representative EA information models are derived. These transformation rules are employed to perform automated model transformations making the first step towards an automated EA documentation. We evaluate our approach using a productive ESB system from a leading enterprise of the fashion industry.

Extending the method of Bedell for Enterprise Architecture
- 2011
-
Ingår i: Proceedings of the Enterprise Distributed Object Computing Conference Workshops (EDOCW). - 9780769544267
-
Konferensbidrag (refereegranskat)abstract
- If and where IT investments should be made can be determined with the help of IT portfolio valuation instruments. An interesting approach is Bedell?s method. However, this method originates from a time where enterprises were structured according to the classical silo architecture. Nowadays the importance of IT has increased, and IT systems and services are more and more interwoven with the business. Enterprise Architecture is a model-based approach that takes into consideration how companies are structured today and how they apply IT. In order to use Enterprise Architecture models in conjunction with Bedell?s method the method needs to be extended. This paper presents an updated version of Bedell?s method that exploits Enterprise Architecture models, in particular the information they contain about the alignment of IT support to the business. In addition, the paper illustrates the application of the method using an example.

The Enterprise Architecture Analysis Tool–Support for the Predictive, Probabilistic Architecture Modeling Framework
- 2013
-
Ingår i: 19th Americas Conference on Information Systems, AMCIS 2013. - : Association for Information Systems. ; , s. 3350-3364

Konferensbidrag (refereegranskat)abstract
- The business of contemporary organizations is heavily dependent on information systems. Business processes and IT are interwoven and numerous technologies are in use. How the involved systems affect each other or impact the organizations' business domain is often uncertain, thus decision-making regarding information technology is challenging. Enterprise architecture (EA) is a holistic, model-based management approach. Many of the available EA software tools focus on documenting and have limited analysis capabilities. In this article, a tool for EA analysis is presented, supporting the analysis of properties such as business fit, security, and interoperability. The tool is implemented to support the Predictive, Probabilistic Architecture Modeling Framework to specify and apply assessment frameworks for performing property analysis on EA models.

Tool Support for Enterprise Architecture Analysis : with application in cyber security

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- In today’s companies, business processes and information technology areinterwoven. Old and new systems as well as off-the-shelf products and tailoredsolutions are used. This results in heterogeneous, often complex ITlandscapes. The impact of changes and the affected systems are difficult toidentify. However, volatile business environments and changing customer requestsrequire organizations to adapt quickly and to frequently make decisionsabout the modifications of their information technology.IT management aims at generating value from the usage of informationtechnology. One frequently used IT management approach is Enterprise Architecture.Company-wide models are used to obtain a holistic picture. Thesemodels are usually created using Enterprise Architecture modeling tools.These tools frequently have strong documentation capabilities. However, theyoften lack advanced analysis functionality. Specifically, such tools do not offersufficient support for the analysis of system properties, such as cyber security,availability or interoperability. The ability to analyze a set of possible scenariosand predict the properties of the modeled systems would be valuablefor decision-making. Changes or extensions could be evaluated before theirimplementation. In other domains, for example, in architecture in its classicalmeaning or in the development of machines, the analysis of models is a commonpractice. Typically, CAD tools are used to perform analysis and supportdecision-making. It is thereby possible to investigate the stability of buildingsor the performance of engines without the need for empirical testing.The contribution of the research work documented in this thesis is a softwaretool with a particular focus on the analysis of Enterprise Architecturemodels and thereby support for decision-making. This tool combines stateof-the-art Enterprise Architecture tooling with advanced analysis capabilitiesthat, until now, were only offered by modeling tools for other domains. Thepresented tool possesses two components. One component allows the creationof a metamodel capturing Enterprise Architecture analysis theory, for example,relevant concepts in the context of cyber security and how they relateto each other. The other component supports the instantiation of the metamodelinto an Enterprise Architecture model. Once a model is in place, itcan be analyzed with regards to the previously specified theory so that, forinstance, a cyber security evaluation can be conducted.The analysis tool was partly developed within the context of a larger researchproject on cyber security analysis. However, the tool is not restrictedto applications within this field. It can be used for the evaluation of numeroussystem properties. Several authors contributed to the tool both on an implementationlevel and in the development and design of the tool’s features. Theperformed research followed the Design Science methodology. First, the objectivesof a tool for Enterprise Architecture analysis were defined. Next, anartifact was designed and developed in terms of a software tool. This tool wasthen demonstrated and evaluated against the objectives. Lastly, the resultswere communicated to both academic and non-academic audiences.
