EA PRELIMS

Architecture

The art and science of designing complex structures, which involves fundamental concepts or properties of a system in its environment, embodied in its elements, relationships, and in the principles of its design and evolution.[cite: 15]

Enterprise

A collection of organizations that has a common set of goals, objectives, and/or a single targeted outcome.[cite: 15]

Enterprise architecture

A coherent collection of principles, methods, and models that are used in the design and realization of an enterprise's organizational structure, business processes, information systems, and infrastructure.[cite: 15]

Enterprise architecture process

Composed of steps that originate from an idea, which are analyzed and designed, implemented as an operational system, and managed for maintenance and updates.[cite: 15]

Internal Drivers

Pertain to the organizational and IT infrastructure and processes, such as an organization's vision and mission, technology availability, and business process.[cite: 15]

External Drivers

Pertain to the business and IT strategies and standards, such as regulatory frameworks, government laws, and industry/technological standards.[cite: 15]

Strategic Management

The identification, selection, and implementation of an organization's long-term goals and objectives.[cite: 15]

Balanced Scorecard (BSC)

A management system that helps an enterprise to clarify and implement its vision and strategy by viewing the enterprise from customer, financial, internal business process, and learning/growth perspectives.[cite: 15]

Business Model Development

The development of a model that identifies the products or services the business will sell, the target market it has identified, and the expenses it anticipates.[cite: 15]

Business Model Canvas

A template in creating high-level descriptions of new or existing business models consisting of elements like value propositions, key activities, and customer segments.[cite: 15]

Business Architecture

A blueprint of an enterprise that provides a common organizational understanding and is used to align strategic objectives and tactical demands.[cite: 15]

Quality Management

The act of overseeing different activities and tasks within an organization to ensure that the products and services offered, and the means used to achieve them, are effective.[cite: 15]

IT Governance and Support

Involves the processes that ensure the effective and efficient use of information technology in enabling an organization to achieve its goals.[cite: 15]

Control Objectives for Information and Related Technology (COBIT)

An internationally accepted IT control framework that provides organizations with a set of "good practices" that helps in implementing an IT governance structure.[cite: 15]

Information Technology Infrastructure Library (ITIL)

The most widely accepted set of best practices in the IT service delivery domain, composed of documents giving guidance on the provision of good IT services.[cite: 15]

IT Implementation

Involves the process of combining the developed software or application with the other management and engineering processes.[cite: 15]

Capability Maturity Model Integration (CMMI)

A model that provides numerous guidelines for assessing the maturity of an organization and the improvements needed in various process areas to proceed from one level to the next.[cite: 15]

Initial (CMMI Level 1)

Processes are usually impromptu and chaotic.[cite: 15]

Managed (CMMI Level 2)

Processes are planned, performed, measured, and controlled.[cite: 15]

Defined (CMMI Level 3)

Processes are defined in terms of standards, procedures, tools, and methods.[cite: 15]

Quantitatively Managed (CMMI Level 4)

Quantitative objectives for quality and process performance are established and used as criteria in managing processes.[cite: 15]

Optimizing (CMMI Level 5)

Processes are continuously improved in the technological aspect of the organization.[cite: 15]

ArchiMate Specification

An open and independent modeling language for an enterprise architecture developed by The Open Group that describes, analyzes, and visualizes relationships among business domains.[cite: 15]

Symbolic Model

A model that expresses the properties of a system architecture using symbols that refer to reality.[cite: 15]

Semantic Model

A model that interprets the meaning of each symbol in a symbolic model.[cite: 15]

The Zachman Framework

Introduced in 1987, a logical structure for classifying and organizing descriptive representations of an enterprise involving basic interrogatives (what, how, where, who, when, why); it is an ontology, not a methodology.

The Open Group Architecture Framework (TOGAF)

Originated as a generic framework and methodology for developing technical architectures, which evolved into an enterprise architecture framework and method.[cite: 15]

Architecture Capability Framework (TOGAF)

Addresses the organization, processes, skills, roles, and responsibilities required to establish and operate an architecture within an enterprise.[cite: 15]

Architecture Development Method (ADM)

Provides the "way of working" for architects; considered the core of TOGAF, which consists of the stepwise cycle approach for overall enterprise development and requirements management.[cite: 15]

Architecture Content Framework (TOGAF)

Considers four closely related architectural structures in an enterprise: Business architecture, Data architecture, Application architecture, and IT architecture.[cite: 15]

Enterprise Continuum

Comprises various reference models that illustrate how architectures are developed across foundational architectures, including the Technical Reference Model and SIB.[cite: 15]

Model-Driven Architecture (MDA)

A framework by Object Management Group (OMG) that provides an open and vendor-neutral approach to interoperability by structuring software specifications as models and separating logic from platform technology.[cite: 15]

Meta-Object Facility (MOF)

Provides a standard repository of MDA model and defines structures that help multiple groups work with a model while having a standard view.[cite: 15]

Common Warehouse Metamodel (CWM)

An established industry standard for data repository integration, standardized database model representation, schema transformation models, and data mining models.[cite: 15]

XML Metadata Interchange (XMI)

A mapping that expresses Unified Modeling Language (UML) models in Extensible Markup Language (XML) and allows it to be moved around an enterprise.[cite: 15]

Mapping

A key feature of MDA, which is a set of rules and techniques used to modify one model to come up with a new model.[cite: 15]

Computation Independent Model (CIM)

Includes the business requirements and business/domain model describing the state of the enterprise, abstracting the automated data processing system.[cite: 15]

Platform-Independent Model (PIM)

Describes the internal structure of an operating system while abstracting specific details for a particular platform, ensuring specifications do not change across platforms.[cite: 15]

Platform-Specific Model (PSM)

Combines the specifications in the PIM and the details on how a system uses a particular type of platform.[cite: 15]
