Tese (doutorado)—Universidade de Brasília, Faculdade de Ciência da Informação, 2011.; As organizações atuam hoje em um ambiente caracterizado pela mudança constante. Por isso, necessitam de instrumentos que permitam agilidade para adaptar suas estratégias, processos e sistemas µas necessidades de cada momento. A Arquitetura Empresarial (AE) tem sido identificada por pesquisadores como a abordagem adequada para prover a agilidade organizacional, pois permite o conhecimento dos elementos organizacionais favorecendo planejar e realizar as mudanças necessárias. Entretanto, a AE ainda não é uma realidade para a maioria das organizações. Os motivos são a complexidade inerente, a falha das abordagens atuais para lidar com essa complexidade e o custo das ferramentas envolvidas. A AE é uma disciplina em desenvolvimento e requer princípios, teorias e instrumentos adequados µa sua natureza e acessíveis a organizações de qualquer porte. Nesse contexto, este estudo identifica um novo referencial teórico: a AE como Arquitetura de Informação Organizacional (AIO). O estudo propõe, ainda, uma abordagem para a AIO, que se fundamenta nos princípios da colaboração organizacional e nos métodos frágeis. Seu principal objetivo é reduzir a complexidade e o custo da AIO. A solução proposta é avaliada em estudo de caso em uma instituição do sistema financeiro brasileiro. ______________________________________________________________________________ ABSTRACT; Currently...

Dissertação de mestrado em Engenharia e Gestão de Sistemas de Informação; Enterprise Architecture is a guide to an organization‟s competitive fitness. It is the dynamic process of managing enterprise IT change through a planned transformation. This transformation is supported by templates, techniques and recommendations to start from the ground up. The aim of putting an enterprise through this process is to create or boost its competitive edge, but this cannot be accomplishment over the night. The most important assets to this process are the people, namely the architects with their end-to-end vision abilities. The line separating the several roles‟ level, especially the Enterprise, Solutions and domain architects is not clear to the industry and each project has its interpretation. The industry demands a new consultancy role, the Solutions Architect which is not older than 2005 (Alison 2007), to answer the requests for a role that is more than a specialist in a certain technology, the request is for a role with transverse business process knowledge. What this means is that Wipro‟s customers want this kind of consultants to be able to attend a certain topic, transversally to all business processes, no matter what tools will be used to accomplish the solution. One of the challenges is exactly to find a unified definition for this role...

To satisfy new market requirements, manufacturing industry has shifted from mass production that takes advantage of the scale of production, to quality management that optimizes the internal enterprise functions, to e-manufacturing era that leverage intellectual capital via collaborative innovation. In the same time, the product itself is becoming the most important asset for sustainable business success. Consequently, the effectiveness, efficiency and innovation for the development of the product across the whole product lifecycle are becoming key business factors for manufacturing enterprise to obtain competitive advantages for survival. To tackle such challenges, a new business model called collaborative product services in virtual enterprise is proposed in this paper. The architecture of this new model is developed based on the framework and the application of web service and process management for collaboration product service in virtual enterprise. Indeed, it is hoped that this architecture will lay the foundation for further research and development of effective product lifecycle management in virtually collaborative enterprise environment.; Singapore-MIT Alliance (SMA)

Submitted to the Department of Architecture on May 1, 2006, in partial fulfillment of the requirements for the Degree of Doctor of Philosophy in Architecture: Design and Computation Through the use of computational generative procedures in the early stages of design, it is common to generate shapes of complex nature that could only be produced by the combined forces of human imagination and computer power. However the more complex the shapes are, the more difficult it becomes to establish a discourse that embodies the geometrical and spatial properties, as well as the formal attributes of a given shape. Furthermore, it has become problematic to differentiate between one complex shape and another, resulting in some abstract, cumbersome, and sometimes obscure explanation about how the shape came into being. In some cases, designers recur to complex expressions of mathematical nature that, even though they are precise descriptions of the form, do not offer any clear way to refer to them unless a person is trained in the language of mathematics. Design Procedures proposes a way of looking at designs as a procedural enterprise where complex shapes are the result of computational process in a step by step basis.; (cont.) Design Procedures in combination with appropriate descriptions of spatial attributes...

The basis to develop this thesis was performed after executing an internship in ABB Inc. The main objective of the study was to design the organization to operate the procurement function at a new manufacturing campus.The enterprise architecting roadmap was applied to decompose the complex problem of designing an organization into building blocks that could be easily developed. For this purpose, two enterprise architecture tools were applied: stakeholder analysis and enterprise relevant views. Once the basic building blocks of the enterprise were defined, different analytical tools were applied to design the details of each one. The analytical tools applied to this project were process mapping, total cost modeling, organization design and information technology selection.The outcome of the study was the detailed definition of the following building blocks of an enterprise: processes, process costs, organization and information technology. The conclusions of the thesis generalize the applied concepts to companies that are in the situation of starting new operations.; by Leon Felipe Villegas Kavanagh.; Thesis (M.B.A.)--Massachusetts Institute of Technology, Sloan School of Management; and, (S.M.)--Massachusetts Institute of Technology...

peer-reviewed; Service-oriented architecture (SOA) has the potential to provide solutions for enterprise application integration (EAI) problems. While core service platform technologies exist, methodological approaches that link the business domain with the platform infrastructure− a prerequisite for an EAI solution − are only beginning to mature. We present a framework for integrating service-centric software systems that emphasizes service architecture as the key to the application integration problem and that proposes a service-entric integration architecture layer to coherently bridge the gap between business and platform layers. Domain models act as drivers of the architectural development and integration process. A dedicated and empirically developed service-specific architecture solution, based on an adaptation of the QUASAR Enterprise methodology, utilizes service and architecture identification techniques.

Assessment Framework to Monitor and Evaluate e-Government Procurement Systems in India

World Bank

This working paper elaborates on an assessment framework to monitor and evaluate e-government procurement systems in India. This is relevant due to the fact that many government agencies have sought to extend use of e-tendering system implemented in their organization to handle procurement in World Bank funded projects. The World Bank has developed a procedure to assess e-tendering systems for compliance to certain guidelines laid down by Multilateral Development Banks. The World Bank prefers to work with the Government of India in development of a robust mechanism for assessment of e-tendering systems instead of independently assessing e-tendering systems as has been done till date. The Government of India has already established a set-up under Standardization, Quality and Testing Certification (STQC) for assessment of e-procurement systems. From its assessment experience, the World Bank has found that the e-procurement applications deployed in many of the e-procurement installations assessed by the Bank were STQC certified...

In several Enterprise Architectures (EA), the views at the CXO-levels may often be at variance with the views provided to mid-tier and operations levels. As a result of this misalignment, organizations may not be able to fully realize the intended enhancements to business management. Alignment of architecture views with one another, as well as consistency with the overall architecture description of the enterprise can be achieved by developing an epistemological basis for enterprise architecture management. In this paper, an approach to develop such a basis is proposed through use of Omnispective Analysis and Reasoning (OAR), an epistemic framework for managing intellectual concerns. This approach focuses on ensuring that the representation of enterprise concerns captures the necessary information regarding their applicability, correctness and completeness for a given problem scenario, and facilitates development of localized ontologies for describing the behavior of component systems and the interactions between them. An example of architecture view alignment is presented to illustrate the approach.; Computer Society of India (CSI)

This research examined the ongoing development of a Marine Corps-wide, enterprise architecture (EA) approach for assessing the IT planning and investment process, including IT-related programs of record. The EA-approach to an architecture known as the Marine Corps Information Enterprise Technology Strategy (MCIENT-S) is intended to transition Marine Corps into the 21st century by providing Marine Corps leadership with superior decision support. This study evaluated planning and implementation strategies against Return on Investment (ROI) and requirements-based Capabilities Based Assessment (CBA) processes in their contrasting measures of effectiveness. By analyzing the current and proposed additional IT investment performance metrics to enhance the enterprise architecture, the study learned of the need to conduct an organizational analysis of the Marine Corps IT development and portfolio management process. The study begins with a baseline understanding of the current financial environment of EA; from the initial and rapid growth in defense-specific IT acquisitions since 9/11 into the current fiscally constrained environment of FY2013. The rising trend of the last decade of defense (IT) investment yields its own unintended consequences. One noted conclusion is that some procurements have unfortunately occurred outside the intended parameters of the enterprise architecture framework and the DoD acquisition process and thereby created consequences in the IT governance. One recommendation for the Marine Corps leadership is to develop a systematic process to link the MCIENT-S and its two primary ROI processes...

The article of record as published may be located at http://dx.doi.org/10.1016/j.procs.2012.01.031; A desired to-be enterprise architecture is realized through many individual projects that incrementally bring the enterprise toward the target enterprise architecture. There are many alternatives projects and the problem is how to decide among the alternatives given budget and time constraints. This paper presents a real options framework to plan a portfolio of projects to realize a target enterprise architecture. Using DoDAF, we describe a method for defining projects as a collection of compound real options. A switching model is used with Monte Carlo simulation to determine the capability phasing view of DoDAF v2.0. We present a case study of a small defense contractor to illustrate our approach. The model and method contributes a means to value a portfolio of projects to realize an enterprise architecture. The motivation for this research is the development of systems engineering tools to help the Department of Defense realize their net-centric transformation to have a more effective and efficient war-fighting capabilities.

The enterprise transformation plan describes multiple individual projects and systems that collectively deliver the desired capabilities and enterprise architecture. These projects are performed over planning horizons that span several years or more. Deciding on what projects to invest in, when to invest in them, and whether to continue the investment as time progresses is a difficult problem because of the uncertainty involved in the operational environment, the technology, and the associated project risks. This paper argues that enterprise systems acquisition can be modeled using real options to obtain project valuations that consider the environmental uncertainty and guide acquisition decisions. Moreover, because the enterprise architecture involves many projects that are interdependent, a portfolio investment approach is called for. We present a real options framework to plan a portfolio of projects as a collection of compound real options. We illustrate how the model can be applied in a case study derived from the DoD?s transformation plan. The model and method contribute an approach to value a portfolio of projects that intentionally creates options to preserve decision flexibility and acquire the target architecture?s capabilities at lower cost and risk.; The Department of Defense (DoD) has an enterprise architectural vision and an accompanying transformation plan.

The competitive market forces organizations to be agile and flexible so as to react robustly to complex events. Modeling helps managing this complexity. However, in order to model an enterprise, many stakeholders, with different expertise, must work together and take decisions. These decisions and their rationale are not always captured explicitly, in a standard, formal manner. The main problem is to persuade stakeholders to capture them. This article synthesizes an approach for capturing and using the rationale behind enterprise modeling decisions. The approach is implemented through a domain-specific modeling language, defined as an extension of a standard enterprise architecture modeling language. It promotes coordination, enables presenting different stakeholders’ points of view, facilities participation and collaboration in modeling activities—activities focused here on enterprise architecture viewpoints. To present its benefits, such as rapid prototyping, the approach is applied to large organizations in the context of telecommunication service design. It is exemplified on modeling and capturing decisions on a conference service.; Vanea Chiprianov, Yvon Kermarrec, Siegfried Rouvrais, Jacques Simonin

Joint Applied Project; The purpose of this project is to explore the early years of paper-procurement and chart the progression to paperless contracting. This will be followed by the Department of Defense's next step to further improve procurement software and user interface. This will be contrasted against the Army's further refinement of their enterprise system that only removes the paper from the otherwise archaic procurement system. The author, a contracting officer whose background includes programming, business administration, management information systems, geographic information systems, and systems design, will explore the future of possible procurement solutions. This will include web-based enterprise architecture and the user interface.

This thesis investigates the use of Enterprise Architectures ("the logical structuring and classification of descriptive representations of an enterprise") as enablers of alignment between business strategy and information systems in public sector agencies. The scope of this study has been shaped by Australian government policies that have set finn directions for the delivery of community products and services in the electronic domain. Foundation management and information systems theories, empirical studies and public management literature -have been used extensively in grounding this research study. A substantial body of literature has been reviewed, and this study positioned in the context of these prior literary works. In particular, the principal alignment theories have been adopted and the research model developed from the published works of eminent management and information systems researchers. The primary research question asks whether Enterprise Architectures are enablers of business strategy and information systems alignment, and if so, what are the associated alignment enabling processes? The study's four research themes are: (i) Enterprise Architecture frameworks and methods; (ii) architectural completeness; (iii) the social aspects of alignment (management support...

Arquitetura Orientada a Serviços (Service-Oriented Architecture - SOA) _e um modelo arquitetural que visa melhorar a eficiência, agilidade e a produtividade de aplicações empresariais através do uso de serviços e composições de serviços, as quais podem ser executadas tanto de forma síncrona quanto assíncrona. Diferentes tecnologias de software podem ser usadas para implementar SOA, tais como Web services e Arquitetura de Componentes de Serviços (Service Component Architecture - SCA). A primeira _e baseada em padrões XML, ao passo que a segunda provê um modelo de componentes para implementação de serviços e composições de serviços. Em particular, quando composições de serviços assíncronos são executadas, um ou mais erros podem ocorrer concorrentemente nos diferentes serviços, possivelmente ao mesmo tempo, afetando a dependabilidade da composição. Dessa forma, mecanismos de tolerância a falhas são necessários a _m de prevenir que um defeito se manifeste na composição. Neste trabalho, apresentamos o projeto e implementação de um mecanismo de tratamento de exceções coordenadas para arquiteturas orientadas a serviços que permite a criação de composições de serviços assíncronos tolerante a falhas de uma forma flexível.

Enterprise Architecture defines the overall form and function of systems across an enterprise involving the stakeholders and providing a framework, standards and guidelines for project-specific architectures. Project-specific Architecture defines the form and function of the systems in a project or program, within the context of the enterprise as a whole with broad scope and business alignments. Application-specific Architecture defines the form and function of the applications that will be developed to realize functionality of the system with narrow scope and technical alignments. Because of the magnitude and complexity of any enterprise integration project, a major engineering and operations planning effort must be accomplished prior to any actual integration work. As the needs and the requirements vary depending on their volume, the entire enterprise problem can be broken into chunks of manageable pieces. These pieces can be implemented and tested individually with high integration effort. Therefore it becomes essential to analyze the economic and technical feasibility of realizable enterprise solution. It is difficult to migrate from one technological and business aspect to other as the enterprise evolves. The existing process models in system engineering emphasize on life-cycle management and low-level activity coordination with milestone verification. Many organizations are developing enterprise architecture to provide a clear vision of how systems will support and enable their business. The paper proposes an approach for selection of suitable enterprise architecture depending on the measurement framework. The framework consists of unique combination of higher order goals...

Context: Enterprise Architecture (EA) is a discipline which has evolved to structure the business and its alignment with the IT systems. One of the popular enterprise architecture frameworks is Zachman framework (ZF). This framework focuses on describing the enterprise from six viewpoint perspectives of the stakeholders. These six perspectives are based on English language interrogatives 'what', 'where', 'who', 'when', 'why', and 'how' (thus the term W5H Journalists and police investigators use the W5H to describe an event. However, EA is not an event, creation and evolution of EA challenging. Moreover, the ordering of viewpoints is not defined in the existing EA frameworks, making data capturing process difficult. Our goals are to 1) assess if W5H is sufficient to describe modern EA and 2) explore the ordering and precedence among the viewpoint concerns. Method: we achieve our goals by bringing tools from the Linguistics, focusing on a full set of English Language interrogatives to describe viewpoint concerns and the inter-relationships and dependencies among these. Application of these tools is validated using pedagogical EA examples. Results: 1) We show that addition of the seventh interrogative 'which' to the W5H set (we denote this extended set as W6H) yields extra and necessary information enabling creation of holistic EA. 2) We discover that particular ordering of the interrogatives...

CJM is a mechanized approach to problem solving in an enterprise. Its basis is intercommunication between information systems, in order to provide faster and more effective decision making process. These results help minimize human error, improve overall productivity and guarantee customer satisfaction. Most enterprises or corporations started implementing integration by adopting automated solutions in a particular process, department, or area, in isolation from the rest of the physical or intelligent process resulting in the incapability for systems and equipment to share information with each other and with other computer systems. The goal in a manufacturing environment is to have a set of systems that will interact seamlessly with each other within a heterogeneous object framework overcoming the many barriers (language, platforms, and even physical location) that do not grant information sharing. This study identifies the data needs of several information systems of a corporation and proposes a conceptual model to improve the information sharing process and thus Computer Integrated Manufacturing. The architecture proposed in this work provides a methodology for data storage, data retrieval, and data processing in order to provide integration at the enterprise level. There are four layers of interaction in the proposed IXA architecture. The name TXA (DDL - XML Architecture for Enterprise Integration) is derived from the standards and technologies used to define the layers and corresponding functions of each layer. The first layer addresses the systems and applications responsible for data manipulation. The second layer provides the interface definitions to facilitate the interaction between the applications on the first layer. The third layer is where data would be structured using XML to be stored and the fourth layer is a central repository and its database management system.

The successful application of Information Technologies (IT) in an organization depends on the business processes used for managing such technologies. It is widely recognized that the use of the Enterprise Architecture (EA) practice for organizing these technologies into a framework is a key factor for achieving a better IT - business alignment. This article presents a business process model for the IT Management that can be used in medium and large organizations as a framework for modelling and analysing their IT management processes. The main difference between the described model and others found in the literature is that our model places EA concept at the centre of the organization of IT Management activities. It provides a better definition, organization and comprehension of the essential and support IT management activities. The described model is being used in several organizations as a referential framework to improve their current IT Management processes.
