Phase 2 : Technical View Of EA Flashcards
Typical outcomes of an EA program :
- improving business performance by maximizing technology alignment and efficiency
- achieving strategic goals that depend on managing change or implementing new business processes and technologies
- linking multiple networks, systems, applications, services, and databases across the entire enterprise
- improving data exchanges between lines of business
What are the 3 important aspects of EA as contained in the formula EA = X + Y + Z ?
EA = Strategy + Business + Technology
List the 6 core elements of a ‘complete approach’ to EA ?
- Architecture Governance
- Implementation Methodology
- Architecture Framework
- Documentation Artifacts
- Architecture Repository
- Associated Best Practices
What most accurately reflects the definition of EA?
The analysis and documentation of an enterprise in its current and future states from a strategy, business, technology perspective.
What most accurately describes the perspectives of CEO and CIO with respect to EA :
Both the CEO and CIO are stakeholders for the EA. The CEO uses EA to view all aspects of the organization in a consistent way. The CIO sees EA as a way to support capital planning, technology assessment, and operations.
Examples of enterprises :
US Federal Govt
An international humanitarian organization
A hardware store on Main Street
A consortium of academic institutions
The retail banking division of a financial corporation
A manufacturing company, its suppliers, partners and customers
The Federal Railroad Administration within the U.S. dept of Transportation
Describe the concept of a driver :
A Driver is an input into the process of deriving the required capabilities of the enterprise from a strategic, business or technical perspective.
The 2 general types of EA activities :
An ongoing management program and a specific documentation approach
What are the 6 value areas of EA?
- Achieving strategic goals
- Manage change
- Improve business performance
- Improve service delivery
- Control technology costs
- Introducing new technologies
Areas of potential risk for EA programs :
Change the strategic or tactical direction
Make people feel threatened
Cause line of business competition
Expose service or product inefficiencies
Cost justification for EA program
4 areas of impact resulting from the immediate access to information on a global basis :
Personal - dealing with information overload
Technology - large growth in data throughput
Organizational - design for information worker
Economic - shift from manufacturing to innovation of new products
Academic influence on EA from Social and Physical Sciences :
Social science :
- organizational theory
- management theory
- information theory
Physical science :
- computer science
- engineering
- operations research
Describe the concept of EA as a meta approach :
EA integrates such practices as business process improvement, scenario planning, security and portfolio management into a single program that incorporates and understanding of the structure and function of the enterprise .
Vertical columns of the Zachman Framework group EA artifacts by :
The 6 basic interrogative questions of Who, How, What, When, Where and Why
Which EA framework explicitly recognizes the distinction between an Architectural Continuum and a Solution Continuum ?
TOGAF
The Department of Defense Architecture Framework (v.1.0) categorizes the EA artifacts by the following groupings :
All Views, technical views, system views, and Operational Views
What are the 3 broad areas of governance discussed in the course :
EA Governance
Corporate Governance
IT Governance
List definitions of Corporate a Governance :
Deals with ways in which suppliers of finance to corporations assure themselves of getting a return on their investment
The relationship of s company to its shareholders or, more broadly, as its relationship to society
Promoting corporate fairness, transparency and accountability

What are the 4 primary phases of the EA3 Implementation Methodology ?
EA Program Establishment
EA Framework and Tool Selection
Documentation of EA
Use and Maintain the EA
Culture
The beliefs, customs, values, structure, normative rules, and material traits of a social organization. It is evident in many aspects of how an organization functions.
Governance
A group of policies, decision - making procedures, and management processes that work together to enable the effective planning and oversight of activities and resources.
Performance Gap
An identified activity or capability that is lacking within the enterprise to perform below desired levels or not achieve strategic or tactical goals.
Line of Business
A distinct area of activity within the enterprise. It may involve the manufacture of certain products, the provision of services, or internal administrative functions.
Architecture Segment
A part of the overall EA that documents one or more lines of business, including all levels and threads. It can exist as a stand-alone part of the EA
Vertical Component
A type of EA component that is contained within one line of business. Examples include a system, database, or website that serves one line of business
Program
A group of related projects managed in a coordinated way. It usually involves an element of ongoing activity.
Methodology
Defines how EA documentation will be developed, archived, and used; including the selection of a framework, modeling tools, and on-line repository
Executive Sponsor
The executive who has decision-making authority over the EA program and who provides resources and senior leadership for the EA program
Change Management
The process of setting expectations and involving stakeholders in how a process or activity will be changed, so that the stakeholders have some control over the change and therefore may be more accepting of the change.
Capital Planning
The management and decision-making process associated with the planning, selection, control, and evaluation of investments in resources, including EA components such as systems, networks, knowledge warehouses, and support services for the enterprise.
Project
A temporary endeavor undertaken to create a unique product, service, or result
Component
Plug-and-play resources that provide capabilities at each level of the framework. Examples include strategic goals and measures; business processes; information flows and data objects; information systems, web services, and software applications; voice/data/video networks, and associated cable plants.
Framework
A structure for organizing information that defines the scope of the architecture (what the EA program will document) and how the areas of the architecture relate to each other
Enterprise Architecture
The analysis and documentation of an enterprise in its current and future states from an integrated strategy, business, and technology perspective
Artifact
A documentation product, such as a text documentation, system specification, application interface information, diagram, spreadsheet, briefing slides, and/or video clip
In addition to an EA repository and Modeling tool, name 4 other types of tools that can support the EA program :
A graphics tool, a word processing tool, a website development tool, a database, a configuration management tool, and any application development and programming tools that are needed to create or modify EA components such as for example : Webservice development tool, General graphics tool
Best guidance for adopting best practices
Select those practices that are most appropriate for addressing the business and technical issues, with consideration given to current skills and tooling
What is typically included in the EA Management Plan
