Adequate tool support for Enterprise Architecture (EA) and its respective management function is crucial for the success of the discipline in practice. However, currently available tools used in organizations focus on structured information neglecting the collaborative effort required for developing and planning the EA. As a result, utilization of these tools by stakeholders is often not sufficient and availability of EA products in the organization is limited. We investigate the integration of existing EA tools and Enterprise Wikis to tackle these challenges. We will describe how EA initiatives can benefit from the use and integration of an Enterprise Wiki with an existing EA tool. Main goal of our research is to increase the utilization of EA tools and enhance the availability of EA products by incorporating unstructured information content in the tools. For this purpose we analyze task characteristics that we revealed from the processes and task descriptions of the EA department of a German insurance organization and align them with technology characteristics of EA tools and Enterprise Wikis. We empirically evaluated these technology characteristics using an online survey with results from 105 organizations in previous work. We apply the technology-to-performance chain model to derive the fit between task and technology characteristics for EA management (EAM) tool support in order to evaluate our hypotheses. © 2013 IEEE.

Agile business process management is an adaptation of the agile methodology, which is well-known in the area of software development. It supports the tight and efficient collaboration between customer and process analysts when designing processes. However, this methodology requires a governance approach that ensures the high quality of the processes. This article shows the usage of quality models to evaluate business processes in agile business process management environments and its specific challenges. To illustrate the approach, an existing quality model is reused and formalized. Afterwards, a business process in the context of offer management is captured and evaluated by means of this quality model. © by authors.

This paper shares our experiences from a project at Swissport Zurich in 2014. The paper introduces an approach to the data integration using a data mart and discusses key techniques for managing change by single phase of a big data project. Furthermore, we identified key barriers to success in big data projects (e.g. big data skepticism, measurable added value) and elaborated ways to overcome these barriers (e.g. a strong business case, modeling change with an enterprise architecture). © 2016 Walter de Gruyter Berlin/Boston.

Enterprise architecture (EA) management is today a critical success factor for enterprises that have to survive in a continually changing environment. The embracing nature of the management subject and the variety of concrete goals that enterprises seek to pursue with EA management raises the need for management functions tailored to the specific demands of the using organization. The majority of existing approaches to EA management does account for the organization-specificity of their implementation, while concrete prescriptions on how to adapt an EA management function are scarce. In this paper we present a development method for organization specific EA management functions based on the idea of reusable building blocks. A building block describes a practice-proven solution to a recurring EA management problem. The theoretic exposition of the development method is complemented by an fictitious application example. © 2012 Springer-Verlag.

Model-driven engineering (MDE) is a software-engineering paradigm that is being introduced into a growing number of domains. One of the most important success factors for a new MDE approach is the availability of the appropriate tool support for it. Although the literature discusses the development of support tools, only a few reports and analyses are available about the development of tool support for real-life modeling languages and MDE approaches. The goal of this paper is to fill this gap through an experience report about developing a tool-suite prototype for an MDE approach for the process control domain that is capable of supporting the development of real-life process control software. Before the work presented in this paper an initial prototype tool suite was already developed. However, it was not able to adequately support industry-scale projects. The paper starts with an analysis of the past development of this already-existing laboratory prototype and then moves on to a report about the development of the industrial prototype, which is influenced by the findings of the analysis. Then a comparison between the two prototypes is made and the lessons learned are described, which may be useful to practitioners who attempt to develop support tools for an MDE approach that are useful in practice. The most important lesson learned is that when developing tool support for complex modeling languages, the traditional development approach should not be easily rejected. © 2015, Kauno Technologijos Universitetas.
