ESE must account for the concerns, interests and objectives of these agents.
Whereas TSE focuses on output-based methodologies e. These can be usefully grouped into two categories: An example of an asset is hardware and software.
Examples of conceptual items are things like analysis, financial elements, markets, policies, process, and strategy. This categorization of enterprise items comes from the semantic model i. Other enterprise entities of interest are things like information, knowledge, skills, finances, policies, process, strategy, markets, and resources, but these are categorized as "concept" items in this particular schema.
Further details on how to use this metamodel's entities and relationships are provided by Reese There might be different subtypes of computing hardware like computers, servers, desktops, laptops, and mainframes. You can see from this elaboration of these domains that an enterprise architecture "schema" can be quite extensive in the kinds of things it can model.
The less technical domains would be things like policy, market, strategy, transition, financial, knowledge and skill, and analysis. In a typical enterprise architecture schema like this, there could be over a hundred types of modeling objects grouped into these domains. The examples give above are from the Troux Semantics metamodel used in the Troux Architect modeling tool for enterprise architecture activities.
See Reese for more details on how to use the metamodel shown in the figure above. Enterprise architecture frameworks are collections of standardized viewpoints, views, and models that can be used when developing architectural descriptions of the enterprise. These architecture descriptions can be informal, based on simple graphics and tables, or formal, based on more rigorous modeling tools and methods.
These frameworks relate to descriptive models of an enterprise, with conventions agreed in particular communities. There are various frameworks and methodologies available that assist in the development of an enterprise architecture.
Urbaczewski and Mrdalj provide an overview and comparison of five prominent architectural frameworks, including:. Blanchard, B. Systems Engineering and Analysis , 5th ed. Carlock, P.

Examples include a network diagram, a server specification, a use-case specification, a list of architectural requirements, and a business interaction matrix. Artifacts are generally classified as catalogs lists of things , matrices showing relationships between things , and diagrams pictures of things. An architectural deliverable may contain many artifacts and artifacts will form the content of the Architecture Repository.
A building block represents a potentially re-usable component of business, IT, or architectural capability that can be combined with other building blocks to deliver architectures and solutions. Building blocks can be defined at various levels of detail, depending on what stage of architecture development has been reached. For instance, at an early stage, a building block can simply consist of a name or an outline description. Later on, a building block may be decomposed into multiple supporting building blocks and may be accompanied by a full specification.
Building blocks can relate to "architectures" or "solutions". For example, a customer services capability may be required within an enterprise, supported by many SBBs, such as processes, data, and application software. Solution Building Blocks SBBs represent components that will be used to implement the required capability. For example, a network is a building block that can be described through complementary artifacts and then put to use to realize solutions for the enterprise.
The relationships between deliverables, artifacts, and building blocks are shown in Relationships between Deliverables, Artifacts, and Building Blocks.
Figure: Relationships between Deliverables, Artifacts, and Building Blocks For example, an Architecture Definition Document is a deliverable that documents an architecture description. This document will contain a number of complementary artifacts that are views of the building blocks relevant to the architecture.
For example, a process flow diagram an artifact may be created to describe the target call handling process a building block. This artifact may also describe other building blocks, such as the actors involved in the process e. An example of the relationships between deliverables, artifacts, and building blocks is illustrated in Example - Architecture Definition Document. Chung, H. Dedene, G. Dern, G. Doest, H. Dreyfus, D.
