Project Management and Enterprise Information Architecture Essay

attempt computer architecture provides a framework for the course to add new applications, infrastructure, and systems for managing the lifecycle and the value of the current and future environments. Enterprise architecture provides the alignment crossways work strategy, IT strategy, and IT implementation. Enterprise architecture links the enterprise credit line strategy to its IT investments by ensuring a tight integration between the Business, Application, selective information, and Infrastructure architecture layers. each(prenominal) of these aras describes integrated sets of blocks should be selected so that the enterprise cigarette achieve its overall business objectives. They to a fault need to be made available so that projects can use them in the design, development and deployment of IT-base business systems. Enterprise Strategy socio-economic class For most institutions, strategic planning and the efficient execution of related IT projects are hampered by lack of ent erprise-wide views of the current business and IT landscape and it is difficult to establish a flexible, adaptable, and business-driven IT strategy.Therefore, this layer predominately describes an enterprise strategy concerning product portfolio and appropriate customer segments, appropriate language and distribution channels in the prone market environment, competitors and core competencies, and capabilities of the company. Business Layer Developing an Enterprise computer architecture involves providing the process and integrated tools to capture the as-is defer of the organizationthe business and IT ecosystemand the desired, to-be state.Enterprise Architecture facilitates the creation of enterprise blueprints that show how business processes are now and how they can be implemented, exploiting the full range of content of underlying IT architectural building blocks. Application Layer The proliferation of applications, systems and the platforms and their interdependencies make t he process of adding and enhancing IT capabilities a risky proposition for the business unless there is an Enterprise Architecture Strategy.The Applications Layer supports the business and describes the required business functions in the underlying IT application systems. Information layer Information is the fuel that drives business artif symbolizes their flow generates value to the user. To transform raw entropy into meaningful learning that provides additional cortical potential and value to the business is one of the key objectives of the Enterprise Architecture.Infrastructure layerThe infrastructure layer consists of the network, horde and storage infrastructure supporting higher-level functions such as applications, databases or e-mail servers. Due to cost pressure, business stakeholders demand more flexibility and light withal from this layer leading to higher degrees of virtualization and systems consuming less energy, reducing electricity costs. To summarize, Enterpr ise Architecture gives the business and IT stakeholders the big-picture perspective across business processes, information systems and technologies.Applying Enterprise architecture improves the predictability and consistency of project outcomes across the portfolio. Consistently repeatable and thus predictable project success is of utmost importance to achieve an orderly variety required for driving effective and lasting transformations such as SOA initiatives while managing associated, inherent risks.Conceptual Approach to EAI credit entry Architecture Information architecture The information architecture helps develop the information-centric, echnically compatible systems by providing a logical approach to information engine room across a Line of Business (LOB) or a larger organization. The information architecture provides the foundational information- pertinent concepts and frameworks for dealing in a consistent and integrated manner with the engineering science to guarante e the responsiveness and trusted information insight that the business requires from its Information Layer.The information Architecture identifies the information centric components of an organizations IT environment and defines its relationship to the organizations objectives. The information architecture also describes the principles and guidelines that enable consistent implementation of information technology solutions, how data and information are both governed and shared across the enterprise, and what needs to be done to pull ahead business-relevant trusted information insight.Following are some examples of the core principles that guide an Information Architecture. * Access and exchange of information- Information services should provide unconstrained chafe to the right users at the right time. * Service re-use- Facilitate discovery, selection and re-use of services and whenever possible encourage the use of uniform interfaces. * Information governance- Adequate informatio n technology should support the efficient execution of an Information Governance Strategy.Standards- A set of coherent standards for data and technology should be defined to promote simplifications across the Information Infrastructure. Enterprise Information Architecture The Enterprise Information Architecture is the framework that defines the information-centric principles, architecture models, standards, and processes that form the basis of making information technology ratiocinations across the enterprise. The EIA translates the business requirements into informational strategies and defines what data components are needed by whom and when in the information supply chain.Furthermore, it addresses the need of the business to generate and maintain trusted information that is delivered by relevant data components. So why do we distinguish between an Information Architecture and an Enterprise Information Architecture? The enterprise in the definition adds the enterprise-wide busine ss context to the definition of Information Architecture. The challenges faces by most organizations, from government to public enterprises, depend upon consistent decision making across multiple business units, departments, and someone projects.The EIA is a core component of the required framework for effective decision making by defining the guiding principles that dictate the organizations strategy to address business needs and the information centric technology infrastructure that supports them. The EIA defines the technical capabilities and processes the organization needs to manage data and information over its lifetime, optimize content-based operational and accordance processes, establish, govern and deliver trusted information, and optimize business performance.By aligning business needs with the technology and the information flows in the supply chain, EIA delivers flexibility agility and responsiveness to the business process and the organization as a whole. The primary goal of the EIA is to reduce complexity and thereby contribute to the elimination of all the factors that act as the inhibitors to change and address new business paradigms.Primary characteristics that can be used to distinguish a well-defined EIA implementation include the chase Gaining transparency- The information remains independent from application specifications, application implementations, and user interfaces. It provides a transparency layer between the information and application domains. * Considering enterprise business requirements- The architecture takes into account the overall information needs of the enterprise and specific LOBs or individual organizations.* Avoiding inconsistencies. It helps identify inconsistencies, conflicts, overlaps, and gaps in the data and information, and offers a concept, framework and methods to resolve this, and it is reclaimable to select adequate solutions. Managing Service Level Agreements (SLA) It provides mechanisms for the defini tion and management of information-centric SLAs which can be monitored and enforced. * Enable decision making- The architecture enables more consistent and efficient IT decision making that is linked to business needs. It does this because it is both flexible and extensible. * Addressing reusability aspects. Enforcing and EIA means that information assets are shared and reused, avoiding data multiplication and thus reducing development, service, and support costs. * Addressing data scope.The information origin Model used by the enterprise describes the scope of the used data information supported by the EIA.* Defining a technology strategy. It establishes the framework upon which strategies adopted by the enterprise depend. In addition, it defines the set of principles that guide how an organizations information systems and technology infrastructure are engineered. source Architecture The reference architecture provides a proven template for architecture for a particular domain or area of application that contains the supporting artifacts to enable their use.The abduce Architecture incorporates best practices resulting from work on a particular field and it also provides a common vocabulary to enable a common agreement while facilitating discussions around implementations. A reference architecture encapsulates at an abstract level the results and best practices derived from multiple deployments of solutions to a given business problem. They enable the limpid sequence of tasks required to build a complete system. Reference Architectures provide a common format that facilitates the design and deployment of solutions repeatedly in a consistent manner.This, they are a valuable tool for IT Architects to help identify and assess gaps and reduce risks in the solution deployment cycle. Based on the requirements in a given area of an application, there are certain components shared between systems in the same area. The Reference Architecture identifies these compo nents and indicates how they interconnect. The following are some key Reference Architecture characteristics. * Major foundational components or building blocks- They help to describe an end-to-end architecture solution. Common language- It simplifies communication when talking about systems of a given type.* Framework- The Reference Architecture is a framework for scope identification, roadmap definition, risk assessment, and gap assessment. * Foundation. It is a proven foundation for all solution designs in a domain (e. g. e-business solutions) The Reference Architecture leverages ideas from successful past implementations and lessons learned from troubled or failed projects and concentrates on simplifications, reuse, and usability, avoiding the complex details of the specific technology.It has the potential to evolve over time, meaning that afterwards it has been constructed it requires maintenance with harvesting of best practices from projects as they are completed, including changes or additions to the Reference Architecture to handle situations that were not addressed. Within the wider solution architecture and deployment scope, there are significant advantages to using Reference Architectures. Following are few examples.
