Project Management and Enterprise Information Architecture Essay

opening computer computer architecture provides a framework for the wrinkle to add new diligences, infrastructure, and systems for managing the lifecycle and the value of the ongoing and future environments. Enterprise architecture provides the alignment across occupation strategy, IT strategy, and IT execution of instrument. Enterprise architecture links the effort barter strategy to its IT investments by ensuring a tight integration among the affair, Application, info, and al-Qaida architecture layers.Each of these argonas get outs integrated manages of blocks should be selected so that the enterprisingness can achieve its overall business objectives. They also need to be made available so that projects can use them in the design, training and deployment of IT-base business systems. Enterprise Strategy stratum For most institutions, strategic training and the efficient execution of related IT projects argon hampered by lack of try-wide views of the current bus iness 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 delivery and dispersion channels in the given(p) market environment, competitors and vegetable marrow 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 extract of the physical compositionthe business and IT ecosystemand the desired, to-be state.Enterprise computer architecture facilitates the creation of enterprise blueprints that install how business processes atomic number 18 now and how they can be implemented, exploiting the full aim of capability of inherent IT architectural building blocks. Application Layer The proliferation of performances, systems and the platforms and their interdepe ndencies come to the process of adding and enhancing IT capabilities a findy proposition for the business unless there is an Enterprise computer architecture Strategy.The Applications Layer supports the business and describes the need business functions in the underlying IT application systems. Information layer Information is the fuel that drives business artifacts their tend generates value to the user. To transform raw data into meaningful randomness that provides spare insight and value to the business is one of the pigment objectives of the Enterprise architecture.Infrastructure layerThe infrastructure layer consists of the network, server and storage infrastructure documentation higher-level functions such as applications, databases or e-mail servers. Due to cost pressure, business stakeholders demand more tractableness and agility also from this layer atomic number 82 to higher degrees of virtualization and systems consuming less energy, reducing electricity costs. To summarize, Enterprise Architecture gives the business and IT stakeholders the big-picture perspective across business processes, training systems and technologies.Applying Enterprise architecture improves the predictability and consistency of project outcomes across the portfolio. Consistently repeatable and thus foreseeable project success is of utmost importance to achieve an orderly reposition required for driving effective and lasting transformations such as SOA initiatives bandage managing associated, inherent risks.Conceptual Approach to EAI Reference Architecture Information architecture The cultivation architecture helps develop the information-centric, echnically compatible systems by providing a reconciled approach to information applied science across a Line of Business (LOB) or a larger organization. The information architecture provides the foundational information-relevant concepts and frameworks for dealing in a consistent and integrated manner with the en gine room to guarantee the reactivity and rely 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 divided up across the enterprise, and what ineluctably to be done to gain 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 access to the reclaim users at the right time. * Service re-use- Facilitate discovery, selection and re-use of services and whenever workable encourage the use of uniform interfaces. * Information govern ance- Adequate information technology should support the efficient execution of an Information Governance Strategy.Standards- A get up 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 devising information technology decisivenesss 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 a dds the enterprise-wide business context to the definition of Information Architecture. The challenges faces by most organizations, from government to public enterprises, depend upon consistent decision making across dual business units, departments, and individual 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 postulate 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 form processes, establish, govern and deliver trusted information, and optimize business performance.By aline 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 organizati on as a whole. The primary goal of the EIA is to dilute complexity and thereby contribute to the excreting 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 exculpated EIA implementation include the following 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 useful to select nice solutions. Managing Service Level Agreements (SLA) It provides mechan isms for the definition and management of information-centric SLAs which can be monitored and enforced. * modify 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 chain.The information Reference 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. Reference Architecture The reference architecture provides a proven templet for architecture fo r a particular domain or area of application that contains the supporting artifacts to enable their use.The Reference Architecture incorporates exceed practices resulting from work on a particular field and it also provides a common land phraseology to enable a common understanding 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 logical 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 Refer ence Architecture identifies these components 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 well-educated from troubled or failed projects and concentrates on simplifications, reuse, and usability, avoiding the complex details of the specific technology.It has the authorization to evolve over time, meaning that after it has been constructed it requires maintenance with harvesting of best practices f rom 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 employ Reference Architectures. Following are few examples.
