In addition to that model, EA specifies security requirements for traceability of Privacy and Technical Security Requirements to Business Process Security and Privacy Considerations and the crosswalk of NIST SP 800-53 and ETA Security Requirements. The Business Process Model includes: Process hierarchies in the form of decomposition diagrams that show structure. The business domains support the effective and secure execution of the core mission business functions. Specifically, this risk assessment estimates the relative degree of security risk associated with major system components.

These standards contain technical criteria specific to the usage of technologies. Functions that are organized primarily by the business areas described in Business Processes. Designers: support the following design activities: Ensuring that their project scope is unique and well understood by the project team, key stakeholder and sponsors. Ensuring that their project scope is unique and well understood by the project team, key stakeholders and sponsors. Ensure that projects that develop application services can make certain of these services available to other IRS business systems in order to promote re-use of application functionality and to eliminate duplication of effort and redundant data. IRS business processes are associated with the specific Location Types at which they are performed in process / location type matrices. However in many cases, the performance goals specified by these matrices are incomplete. Focus on the future state defined as five years out and beyond. 2. The EA provides business scenarios that demonstrate how selected business processes contained in the EA support key business events. Enterprise Architecture ComponentsEnterprise Architecture components include: 1. Business Information Systems: A Business Information System is a computer-based business information system that is being managed through the Metabase. It provides high-level perspectives of the application architecture, the data architecture, and the conceptual technology architecture views. The IRS EA describes processing threads that are used to demonstrate how system software applications are involved in executing high-level business processes. Vendor product lifecycles change and the ESP alignment captures the information at approval but may be updated when needed or detected to synchronize with industry changes. all of the following statements are true: a) It must have the KDAL (Knowledge, Detect, Adjust, Learn) capabilities b) it must be well integrated Select one: True False About ICT4SIDS site, which ones of the following statements are true (please pick only 3… As such, these Work Products are the core of the IRS EA.

Reporting compliance (remote assistance) requiring an exam. Given the broad scope of many of the referenced requirements, some provisions of some of these requirements may not be fully applicable to the IRS business systems modernization program. Microsoft 365 for enterprise plans and which components they contain. Ensuring that their work is integrated with other projects and within the operating units. Data Strategy: develops a coherent approach that will reduce data redundancy and the large operating costs caused by multiple, replicated or similar data stores. A logical data model takes the conceptual model down a level of detail to the concerns of technical staff rather than the business users. Relationships between the functions and the data, depicted as objects in UML notation. In addition, the blueprint is available online for all IRS employees and contractors with access to the intranet, and anyone may contact the EA team with proposed changes, which the EA team evaluates, prioritizes and incorporates as appropriate. Purpose: An enterprise architecture is a strategic information asset base which defines the mission, the information and technologies necessary to perform the mission and the transitional processes for implementing new technologies in response to the changing needs of the mission. Application architecture. It encompasses three tiers of the distributed computing architecture and includes data and voice networks, call centers and video communication and other physical components of IRS' IT environment. Prioritizing various projects and related investments. STM identifies, approves, and manages the technology products, service contracts (including cloud), and standards that define the business initiatives affecting IT. The IRS EA provides access to a collection of resources that describe service-oriented architecture (SOA) within the EA and support IRS projects in achieving and demonstrating their compliance with the EA. The ESM solution deployed at the IRS must be flexible enough to adapt to a wide variety of operational models. Sensitivity Classification of ECDM Data Classes (part of the Data Requirements work product). through 3.5.6 identify the enterprise’s architecture products and explain their contents from both a row and column perspective. Exempt organization (IRC Section 6104) public disclosure of 527, Taxpayer receives individual assistance with unpaid balance for previous year’s taxes.

It also provides information on service definition. An official website of the United States Government. The plan further demonstrates incremental stages necessary to achieve target state business objectives, program efficiencies, and technology advances. In general, the IRS EA presents a multi-layer technology architecture. (Sensitivity classification indicates whether a data class is sensitive or non-sensitive and, if sensitive, its sensitivity type [for example, Taxpayer, Employee Personal, Law Enforcement].) Enterprise architecture regards the enterprise as a large and complex system or system of systems. Each is described in more detail in the following subsection but both pertain to organizing the data needed for the administration of the business of the IRS. Chapter 3: enterprise systems architecture. The key role of an ERP system is to provide support for such business functions as accounting, sales, inventory control, and production.

The IRS has added custodial requirements to manage the receipt and disbursement, and related assets and liabilities, of taxpayer accounts. The RA also documents dependencies between different projects and their releases.
