Enterprise Architecture and Its Implementation in Federal Domain
Enterprise Architecture and Its Implementation in Federal Domain Definition of Enterprise Architecture (EA) and Federal Enterprise Architecture According Michael Platt, ââ¬Å"enterprise architecture (EA) is a conceptual blueprint that defines the structure and operation of an organizationâ⬠(Platt 5). This definition takes into account how ââ¬Å"an organization can effectively use EA to achieve both its current and future aimsâ⬠(Platt 5).Advertising We will write a custom essay sample on Enterprise Architecture and Its Implementation in Federal Domain specifically for you for only $16.05 $11/page Learn More This means that an organization must define its business vision and strategies in terms of enterprise aspiration by determining, improving, and communicating main needs, rules and models which demonstrate the organizational future aspiration and create chances for its development. The EA scope must include people, information and technology, stages, existing relationships, and contacts with the external fa ctors. EA provides whole-system solutions that cater for business opportunities and challenges of the organization and offer solutions needed for the implementation of the EA system. EA offers advantages in terms of enhancing decision-making, adjusting according to the needs of the market, avoidance of redundancy and inefficiency, making maximum use of organizational resources, and reduce staff turnover. The Federal Enterprise Architecture (FEA) is an initiative by the Federal government to combine its agencies and their related functions under one and available-everywhere enterprise architecture. FEA initiative is still under development, and its main applications are not yet available. However, the program started long ago, and there has been failures, and improvement in its development. Studies view FEA has a system with only five performance models. These include service, data, business, technical and data models. However, under these models, FEA offers much more than what we ca n see. The five models entail ideas on how we should view EA under the segment models. There are also collections of reference models to demonstrate various aspects of the EA under the five models, and also stages of developing an EA platform. This model provides opportunities for movement from a pre-EA to post-EA model. EA also has a cataloging taxonomy for resources that are within its scope. In addition, it also has a measuring system that determines its success in enhancing business values. This analysis shows that EA has many components that the models highlight. It offers the necessary materials needed to create an EA for the most complex and elaborate organizations like the US government.Advertising Looking for essay on business economics?

Get your first paper with 15% OFF Learn More The FEA-Program Management Office (FEAPMO) puts it in totality that FEA offers a common language and framework to describe and analyze IT in vestments, enhance collaboration and ultimately transform the Federal government into a citizen-centered, results-oriented, and market-based organization as set forth in the Presidents Management Agenda (The Chief Information Officers Council 25). Fig 1: Segment map of the federal government Enterprise Architecture Framework and Federal Agencies and their mission alignment The FEA offers a general approach for acquiring information technology (IT), using and discarding within the Federal government domain. In this respect, EA helps the Federal government aligns its resources so as to enhance business values and assist government agencies to perform their main missions. In addition, it offers a plan for transformation from the existing state to the preferred future state. Thus, FEA is an EA that will help the Federal government achieve its desired objectives. The US government based this platform on Clinger-Cohen Act and attempts to align it with the budget. The main aim of the FEA is to facilitate ââ¬Å"sharing of information, enhance service provision for citizens, and reduce costsâ⬠(CIO Council 24). The FEA works on a common platform that allows for IT acquisition within the Federal government (CIO Council 24). FEA has offered E-governance, change management, program management and deployment system in the Federal government missions. It is the responsibility of the agency to control and manage the processes and applications of the EA in service provisions and policies implementation. Every agency is also responsible for sponsoring their EA at the executive level, allocation of resources, and appointing its Chief Architect. The agencys office carries out the maintenance, development and implementation of the EA. This implies that all agencies must have the capacity to manage any change in the system, artifacts, and EA documents. At the same time, every agency must be in a position of facilitating the deployment and accessibility of EA content to the ir intended recipients and user community.Advertising We will write a custom essay sample on Enterprise Architecture and Its Implementation in Federal Domain specifically for you for only $16.05 $11/page Learn More This should also include training, communication and repository deployment. Further, for accountability, every agency must be able to avail the artifact in every level of EA and offer justification in case of failure to provide artifacts. The rationale for using this approach is to ensure effective governance and management of policies according to the compliance and alignment with the EA procedures, and stages in order to offer the executive the needed support. Change and system setups are essential parts of managing the EA system. This is necessary so as to keep EA processes and outcomes current for factual information due to its role in IT investing and agencies strategic planning. All the stakeholders of the EA must be able to understand its processes and outcomes. Overview of the Federal Enterprise Architecture The FEA functions as a business-based framework for the Federal government and its agencies. It helps in developing IT investment portfolios according to different Federal agencies processes and functions, in addition to providing cross-agency requirements. The FEA has many artifacts under its various models to support the agencies functions and processes. The FEA framework works under five models in order to provide benchmark terms and scopes of EA; thus, it facilitates ââ¬Å"collaboration and sharing of information among the federal government agenciesâ⬠(Bernus and Nemes 179). Business Reference Model The Business Reference Model (BRM) provides the business side of the different roles of the Federal government. For instance, under natural resources, BRM may provide a benchmark business function as water resource management. We may take this as a line of business function for citizensââ¬â¢ business ar ea. The BRM is mainly framework that relies on function capabilities so as to describe functions of the business Federal government, irrespective of the Federal agencies that carry out such duties. The BRM gives step-by-step and organized patterns for describing the daily business activities of the Federal government through a performance-based approach. The BRM is the top layer of FEA, and it serves the main purpose in ââ¬Å"data analysis, technology, and service components viewpointâ⬠(CIO Council 24). It has four domains. Services For Citizens Mode of Delivery Support Delivery of Services Management of Government Resources The BRM framework is rather functional than organizational in relations to the Federal government. The BRM overrides the functions of agencies in describing duties such as internal operations and services accorded to the citizens independent of the performing office, bureaus, or agency.Advertising Looking for essay on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More It describes the Federal government based on general business areas instead of each agency. This approach enhances collaboration among various agencies and makes the BRM serves the main purpose of the E-government strategy and the foundation of FEA. The BRM offers an improved approach to the Federal government operations. However, we must note that it is only a model which we can only realize its effectiveness when used well. It core approach can facilitate low collaboration and description in Federal government. In addition, it can achieve little in accomplishing the aim of ââ¬Å"the E-government if policymakers do not incorporate it into EA and as part of management platform of all Federal branchesâ⬠(CIO Council 24). Components Reference Model (CRM) The Component Reference Model provides a performance-driven and business view of the platforms, which can offer support to the business functions of the agencies. It may also classify service components along the line of the sup port they provide or performance objective they fulfill. The main purpose of the CRM is to support the discovery of the Federal government business and use of service components in the investments of IT and resources. The CRM relies on both vertical and horizontal scopes, which are independent of the function of the business. It can offer a leverage foundation that can ââ¬Å"support parts, business services, application functionalities, and the reuse applicationsâ⬠(CIO Council 24). The CRM domain consists of the following components ââ¬Å"Customer Services, Process Automation Services, Business Management Services, Digital Asset Services, Business Analytical Services, Back Office Services, and Support Servicesâ⬠(CIO Council 24). These domains have their Service Types. For instance, under Customer Service Domain, we may find ââ¬Å"other three sub-domains, namely, Customer Relationship Management, Customer Initiated Assistance, and Customer Preferencesâ⬠(CIO Counc il 24). Technical Reference Model (TRM) The TRM provides definitions of ââ¬Å"benchmarks and different technologies that architects can use in creating IT platformsâ⬠(USA Government 1). For instance, TRM may create a ââ¬Å"definition of HTTP under a subset of the transport systemâ⬠(Bernus and Nemes 179). TRM has parts and technical framework that differentiate information technologies and service standards so as to allow delivery and access of Service Components and functionalities. TRM also functions as a unifying platform of E-government and existing agencies by offering a basis that enhances the reuse and adaptability of Service Components, and IT from a wide view of Federal government. The basic parts of TRM are mainly the following. TRM has Service Areas. These mainly represent complex layers that support a secure creation, swap, access and delivery of Service Components. Every Service Area sums up technologies and standard into functional areas of low-level tiers . This place also has several categories and standards of Service Components. This step-by-step arrangement of layers offers the framework to technologies that ultimately provide support for the Service Areas. TRM also has Service Categories. These sections group the low-level technologies according to their functions and business utilities they fulfill. As a result, a Service Category will also contain its components of Service Standards. There are also Service Standards in TRM. Service Standards mainly depict the technologies and standards that provide support for a Service Category. Most Service Standards use ââ¬Å"illustrations and specifications of plain text as indicators so as to support mapping of the agency into TRMâ⬠(Bernus and Nemes 179). TRM uses a general, ââ¬Å"collaboration, standard vocabulary, interagency discovery, and interoperability to align Federal capital investmentsâ⬠(Bernus and Nemes 179). This approach offers the Federal government and its age ncies opportunities for taking advantage of economies of scale through ââ¬Å"identifying and reusing the best technological solutions for enhancing missions, and business applications in the model architectureâ⬠(Bernus and Nemes 179). The hierarchy of TRM defines the technologies and standards that function in support of the FEA and create secure channels of delivery, swap, and building of business and functional Service Components. These applications work in a service-oriented or component-based architecture. Data Reference Model (DRM) The DRM defines the ââ¬Å"total level, information, and data that offer solutions to government program and operations lines of businessâ⬠(Bernus and Nemes 179). DRM provides opportunities for different agencies to define the ââ¬Å"types of involvements and interactions that happen between the citizens and Federal governmentâ⬠(Bernus and Nemes 179). DRM offers a thorough creation of the government information into a high degree o f details. DRM also provides a chance for grouping Federal data and notice any duplicates regarding data constructs. Performance Reference Model (PRM) The PRM focuses on providing standard methods of stating the value that the EA delivers. According to PRM, quality may be a technological gauge area that defines how technology can fulfill functionality and requirements in its role. Thus, PRM assists in generating improved information content for enhancing day-to-day decision-making and strategic options. PRM also enhances alignment of inputs and outputs in order to distinguish the outcomes of the desired results. In addition, it also enables policymakers identify areas of improvement across the organization. The PRM relies on many ways of carrying out functional measurement. These methods include the Balance Scorecard, the Theory of Constraints, Methodology for value measuring, Baldrige Criteria, Value chain, and Program logic. Further, the PRM uses methods within the agencies for me asuring, such as ââ¬Å"GPRA, EA, PART assessments, Investment Control and Capital planningâ⬠(CIO Council 24). The PRM has four areas of measuring functionalities in the EA. Mission and Business Results Customer Results Processes and Activities Technology FEA and Managerial Flexibility The FEA initiative provides strategic options that may allow the system to change scale, defer, explore, grow or combine sequential together. These adaptabilities allow the FEA to use the options for analysis of further details through breaking down and relating each area in building decision trees for benefits of making optimal decisions. Thus, managerial flexibility in the system provides opportunities for the investment to conduct any analysis in case of availability of new information. However, the presence of flexibility in the system changes characteristics of the FEA risk initiative. Consequently, this changes the cost of capital (Brach 370). In this context, risk management forms the b asis of incorporating flexibility in the system. Analysis of Real Options The second to last step under-investment plan relies on analyzing the benefits in the decision tree by applying risk-neutral or repeating portfolio methods. The calculation takes into account many investment portfolios depending on various perceptions of risks and related trade exchanges. According to Benaroch, there are several configurations that we cannot exhaust; thus, he suggests ââ¬Å"three rules of excluding implausible configurationsâ⬠(Benaroch 45). First, ââ¬Å"consistency between sequences of options in an investment configuration with the sequence in which options materialize in the investment lifecycle, second, ability of options to coexist in an investment configuration, and finally, consideration for configurations involving maximal subsets of viable optionsâ⬠(Benaroch 45). The concept of Reuse and Cost Saving in Enterprise Architecture best practices Reuse shows agency achievement in moving towards their target functionality and sharing of services content, and building an environment of service within the agency. Gauging the agency achievements in terms of sharing information usually focuses on reuse. The system uses varieties of arrangements and other similar patterns to measure agency results and combine all requirements in the process of procurement. It can also measure the agency achievements in terms of building a positive service environment so as to enable both the consumption and production of general data, services and component services. At the same time, it will also measure investment accuracy and its mapping categories together with consistency of the Service Reference Model service parts, and TRM service mappings (Groth 51). For an EA to be effective, it must identify chances of consolidating, reuse, sharing, and standardizing. This enhances effectiveness in mission and financial performance among the agencies. This is the only way an agency ca n justify its massive spending in advanced IT systems i.e. by achieving superior outcomes of mission performance (The Chief Information Officers Council 2). Likewise, every agency must demonstrate its reuse of Service Reference Model components, information, infrastructure, and other services and increased levels of services sharing among agencies. Further, agencies must demonstrate an application of a combined purchasing power by reuse of contract and procurement methods for getting needed services. The definitions of segments in a global context enable their reuse across several agencies. For instance, we can map out an application of a given segment, and then apply the same map in other areas of the aim of EA reuse. This indicates that all segments, whether vertical or horizontal, are suitable for facilitating the concept of sharing among the agencies (Sauer and Willcocks 497). Therefore, the initiative of FEA will ensure that the Federal government rectifies the existing lack of integration, immediate response to changes, and alignment. If the agencies can restore the anomalies, then services provisions to the public will be efficient and at low cost through enhanced government processes of services delivery. FEA has enormous potential for cost reduction and cost avoidance. FEA can make the Federal government realize costs reductions and avoidance through helping Federal agencies depend on a single EA platform, instead of developing and redeveloping several business support systems (Mun 46). Therefore, we can look at costs reduction in terms of economies of scale. This is whereby the FEA locates a common function among the agencies and then shows possible areas of cost-cutting through reuse of systems, models, and the entire processes by collaboration. Cost-saving can also occur through sharing of resources. The FEA identifies possible opportunities of sharing resources, such as support services, IT application and other solutions. Finally, the Federal gov ernment may realize cost saving in terms of conducting market research. The FEA depends on constant study of emerging technologies and their applications across the entire organization. The Federal government can share the research results across its multiple agencies, depending on their shared business functions. This will reduce extra costs and time used in conducting single studies (USA Government 1). There are indicators to show how agencies are using FEA and other IT platforms to control their costs. Cost savings and cost avoidance are long-term initiatives of the Federal government, which improve as the system becomes familiar with users. We can locate indicators of cost avoidance and cost savings from the analyses of financial records of the agencies. Every agency must produce its reports on cost savings and avoidance (Perks and Tony 13). Agencies must demonstrate their declining costs in given percentages over the years in IT spending. This may be in relations to the Federal government budget or other agencies. However, the system also allows for readjustment due to factors of inflation or changes in new IT applications at their initial stages. The agencies can decide to redeploy their savings according to their budgets and processes of executions. We can also estimate costs and perform a valuation of benefits. This stage in the process of investment and subsequent control entails establishing the increase in cash flows due to achievement of the desired EA capabilities. The system uses a basis of discounted cash flow (DCF) in its analysis (Benaroch 43). This base acts as the standard for analyses of the project cost savings and cash flows. The system uses the old methods based on forecasting of revenues and costs so as to determine the net present value (NVP). It also takes into account discounts associated with the costs and revenues and their risks at a given rate. Historical data enables the system to perform an analysis based on time-series forecas ting. In case the data is not available, then ââ¬Å"analysts have to rely on assumptions of the managementâ⬠(Taudes 165). We must also note that most analyses assume no flexibility in pricing (Taudes 165).
