- 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.

- Most conventional conceptual modeling approaches are not putting into a foreground interaction dependencies between actors. This is one of the main reasons why it is difficult to apply them for managing complexity of conceptual representations. The goal of this paper is to present conceptual modeling method, which allows constructing graphical representations of scenarios with a more comprehensible structure. Using simple interaction loops between organizational and technical components help designers to separate crosscutting concerns in system engineering without the requirement to specify a complete solution. The examples of sequential, iterative, parallel and alternative behavior are analyzed to demonstrate conceptual descriptions of use-case scenarios. The overlaying and underlying interaction loops among actors are easier to understand, extend and maintain.

- E-government has become one of the most prominent means to reform the public sector. Building e-government embraces a variety of efforts both at a centralised level, (e.g. the integration of and communication between systems across different agencies, domains and geographies), and at local levels such as the development of e-services for the provision of 24/7 public sector agencies. In this paper, we report on the results of a project aimed to develop e-services as a part of the e-government initiative in Sweden. The project was carried out at the elderly and handicapped unit at one municipality. The e-services considered in the project were also intended to open up the underlying social services and are, therefore, referred to as open e-services. We discuss the results of the development of one such e-service as a proof-of concept solution for which a business process management system is used. We present the solution and explain the features of using a business process management system as a back-end system.
