Enterprise Architecture (EA) has gained importance in recent years, mainly for its concept of “alignment” between the strategic and operational levels of organizations. Such alignment occurs when Information Technology (IT) is applied correctly and timely, working in synergy and harmony with strategy and the operation to achieve mutually their own goals and satisfy the organizational needs.Both the strategic and operational levels have standards that help model elements necessary to obtain desired results. In this sense, BMM and BPMN were selected because both have the support of OMG and they are fairly well known for modelling the strategic level and operational level, respectively. In addition, i* modeling goal can be used for reducing the gap between these two standards. This proposal may help both the high-level design of the information system and to the appropriate identification of the business processes that will support it.This paper presents a methodology for aligning strategy and the operation based on standards and heuristics. We have made a classification for elements of the models and, for some specific cases, an extension of the heuristics associated between them. This allows us to propose methodology, which uses above-mentioned standards and combines mappings, transformations and actions to be considered in the alignment process.

In this chapter the authors show, by using a case study, how it is possible to achieve the alignment between business and Information Technology (IT). It describes several phases of project development, from planning strategy, enterprise architecture, development of businesses supporting tools and keeping dynamic alignment between the business and the IT. The authors propose a framework, framed under an enterprise architecture that guarantees a high level of response to the applications development or configuration as improves its alignment to business by solving some limitations of traditional software development solutions namely: difficulty in gathering clients requirements, which should be supported by the applications; difficulty to connect the organisation processes used to answer the client, which must also be integrated in the applications and the difficulty to develop the applications that can follow the business cycle. To test the approach, this was applied to a real case study consisting in the configuration of an application that manages the relationship with the clients.


The HMM research and development project concept (RDPC) uses factor-driven research and reasoning concept that is supported by a behaviour-driven development environment or a natural language programming that can be easily adopted by any RDPC, where the HMM framework offers such a high level factors editing their logic implementation environment that it can be used by any RDPC researchers without any prior knowledge in computer sciences, technical, or even advanced mathematics. The RDPC is a meta-model that can be used for research topics on enterprise architecture, business transformation or decision-making systems, mathematical models-algorithms. It is supported by many real-life cases. The uniqueness of this RDPC also promotes the future transformation project's unbundling and the alignment of various enterprise resources including services, architecture standards, and strategies to support business transformation processes as the first.

Stakeholder engagement is critical to applying enterprise architecture (EA) principles and methodologies in order to achieve value from information technology (IT) investments. Stakeholders include the business owners, data owners, developers, and technical infrastructure operational staff. Obtaining stakeholder engagement is a continuous process and is necessary at all levels of the organization. It is also an integral aspect of the governance process for IT investments. This chapter addresses the following topics as they relate to stakeholder engagement:• Obtaining high-level stakeholder involvement in EA governing processes and addressing major challenges in building stakeholder engagement.• Illustrating how stakeholder involvement can lead to consolidation and better management of IT investments.• Identifying vehicles to communicate with EA stakeholders while ensuring the architecture accommodates the style and priorities of the stakeholder community.

The concept of operations for NYCT systems is changing as a result of Automatic Train Supervision (ATS) Communications-Based Train Control (CBTC), and Solid State Interlocking (SSI) deployment. Train dispatchers are dealing with a higher degree of automation with ATS systems; and similarly, train operators are adjusting to a split between automated and manual processes with CBTC systems. The emerging CBTC and SSI systems are becoming Information Technology (IT) infrastructure and digital-control based. While CBTC is increasing the overall safety of the signaling system, it is also increasing system complexity, especially from an analysis point of view. These issues are addressed at NYCT by the implementation of DoDAF, which the U.S. Department of Defense Architecture Framework, an Enterprise Architecture. This paper discusses VSI’s application of DoDAF with a focus on the safety certification mission. It begins with an overview of DoDAF, followed by a description of Views and Product-models, the building blocks of DoDAF. Each section presents a high-level description of each View, along with exemplary Product-model descriptions, 1 or 2 per View. In addition, two system capability requirements, Safe Train Separation and Control Speed to Restriction Limits, are examined and mapped throughout the model.

As a result of Hurricane Katrina, the destruction of property, assets, documentation, and human life in the Gulf Port has introduced a myriad of challenging issues. These issues involve human, social, government, and technological concerns. This chapter does not address the many immediate human and social concerns brought forth from a natural disaster or major terrorist attack (NDMTA); this chapter addresses a small but significant problem of reestablishing or laying the groundwork for an enterprise architecture for local government during the response phase of the disaster. Specifically, it addresses constructing a high-level data model and fundamental SOA, utilizing the remaining local assets, XML (extensible markup language), and Web services.

In the past decade, the rush to technology has created several flaws in terms of managing computers, applications, and middleware and information systems. Therefore, organizations struggle to understand how these elements behave. Even today, as Enterprise Architectures grow in significance and are acknowledged as advantageous artifacts to help manage change, their benefit to the organization has yet to be fully explored. In this paper, the authors focus on the challenge of real-time information systems evaluation, using the enterprise architecture as a boundary object and a base for communication. The solution proposed is comprised of five major steps: establishing a strong conceptual base on the evaluation of information systems, defining a high level language for this activity, extending an architecture creation pipeline, creating a framework that automates it, and the framework’s implementation. The conceptual framework proposed avoids imprecise definitions of quality and quality attributes, was materialized in a model-eval-display loop framework, and was implemented using Model Driven Software Development practices and tools. Finally, a prototype is applied to a real-world scenario to verify the conceptual solution in practice.

Process maps provide a high-level overview of an organization?s business processes. While used for many years in different shapes and forms, there is little shared understanding of the concept and its relationship to business process architecture. In this paper, we position the concept of process map within the domain of architecture description. By ?architecting? the concept of business process map, we identify and clarify diverging views of this concept as found in the literature and set requirements for describing process maps. A meta-model for a process mapping language is produced as a result. The proposed meta-model allows investigating the suitability of EA modelling languages as a basis for defining a domain-specific language for process mapping along with the creation of a better understanding of business process architecture in relation to enterprise architecture, which can be beneficial for both BPM and EA professionals.
