Comprehensive Guide to ArchiMate: Aligning Business and IT Architectures

Introduction to ArchiMate

ArchiMate is a powerful modeling language designed for describing enterprise architectures. It provides a clear and structured way to represent the construction and operation of business processes, organizational structures, information flows, IT systems, and technical infrastructure. Unlike other modeling languages such as Unified Modeling Language (UML) and Business Process Modeling Notation (BPMN), ArchiMate stands out with its well-defined metamodel and broader enterprise modeling scope.

Key Features of ArchiMate

Open and Independent

ArchiMate is an open standard, which means it is not tied to any specific vendor or technology. This independence allows for broad adoption and integration across different tools and platforms.

Comprehensive Modeling Language

ArchiMate supports the modeling of various aspects of an enterprise, including business, application, and technology layers. It provides a holistic view of the organization, enabling stakeholders to understand the interrelationships between different domains.

Alignment with TOGAF

ArchiMate is designed to align with the TOGAF (The Open Group Architecture Framework) ADM (Architecture Development Method). This alignment ensures that ArchiMate models can be seamlessly integrated into the TOGAF framework, providing a structured approach to enterprise architecture development.

ArchiMate Layers

ArchiMate distinguishes three main layers: the Business layer, the Application layer, and the Technology layer. Each layer offers services to the layers above it, creating a layered view of service-oriented models.

Business Layer

The Business layer focuses on the products and services offered to external customers, realized by business processes performed by business actors and roles.

Application Layer

The Application layer supports the Business layer with application services, realized by software application components.

Technology Layer

The Technology layer provides infrastructural services needed to run applications, realized by computer and communication hardware and system software.

Dimensions of ArchiMate

ArchiMate models are structured around three main types of elements:

Active Structure Elements

These are entities capable of performing behavior, such as business actors, application components, and devices.

Behavior Elements

These are units of activity performed by active structure elements, such as business processes, application functions, and technology services.

Passive Structure Elements

These are objects on which behavior is performed, such as business objects, data objects, and artifacts.

Core Concepts and Relations

ArchiMate defines a set of core concepts and relationships to model the interactions and dependencies between different elements of an enterprise architecture. These include:

Structural Relationships

• Association: A general relationship between objects.
• Access: The access of behavioral concepts to business or data objects.
• Used By: The use of services by processes, functions, or interactions.
• Realization: The link between a logical entity and a more concrete entity that realizes it.
• Assignment: The link between units of behavior and active elements that perform them.
• Aggregation: The grouping of objects.
• Composition: The composition of objects from other objects.

Dynamic Relationships

• Flow: The exchange or transfer of information or value between processes, functions, interactions, and events.
• Triggering: The temporal or causal relationships between processes, functions, interactions, and events.

Other Relationships

• Grouping: The grouping of objects based on a common characteristic.
• Junction: The connection of relationships of the same type.
• Specialization: The specialization of an object.

Business Layer Meta-Model

The Business layer meta-model includes concepts such as business actors, business roles, business collaborations, business interfaces, locations, business processes, business functions, business interactions, business events, business services, business objects, representations, meanings, values, products, and contracts. These concepts help model the static structure, behavior, and passive elements of the business layer.

Business Actor

A business actor is an organizational entity capable of performing behavior. Examples include humans, departments, and business units.

Business Role

A business role is the responsibility for performing specific behavior, to which an actor can be assigned.

Business Collaboration

A business collaboration is an aggregate of two or more business roles that work together to perform collective behavior.

Business Interface

A business interface is a point of access where a business service is made available to the environment.

Location

A location is a conceptual point or extent in space, used to model the distribution of structural elements.

Business Process

A business process is a behavior element that groups behavior based on an ordering of activities, intended to produce a defined set of products or business services.

Business Function

A business function is a behavior element that groups behavior based on a chosen set of criteria, such as required business resources and competences.

Business Interaction

A business interaction describes the behavior of a business collaboration, performed by multiple roles.

Business Event

A business event is something that happens and influences behavior, such as a customer request or an internal trigger.

Business Service

A business service is a service that fulfills a business need for a customer, exposing the functionality of business roles or collaborations to their environment.

Business Object

A business object is a passive element that has relevance from a business perspective, such as a customer record or an insurance claim.

Representation

A representation is a perceptible form of the information carried by a business object, such as a document or a message.

Meaning

Meaning is the knowledge or expertise present in a business object or its representation, given a particular context.

Value

Value is the relative worth, utility, or importance of a business service or product, expressed in monetary or non-monetary terms.

Product

A product is a coherent collection of services, accompanied by a contract or set of agreements, offered as a whole to customers.

Contract

A contract is a formal or informal specification of agreement that specifies the rights and obligations associated with a product.

Application Layer Meta-Model

The Application layer meta-model includes concepts such as application components, application collaborations, application interfaces, application functions, application interactions, application services, and data objects. These concepts help model the active structure, behavior, and passive elements of the application layer.

Application Component

An application component is a modular, deployable, and replaceable part of a software system that encapsulates its behavior and data and exposes these through a set of interfaces.

Application Collaboration

An application collaboration is an aggregate of two or more application components that work together to perform collective behavior.

Application Interface

An application interface is a point of access where an application service is made available to a user or another application component.

Application Function

An application function is a behavior element that groups automated behavior that can be performed by an application component.

Application Interaction

An application interaction describes the behavior of an application collaboration, performed by multiple application components.

Application Service

An application service is a service that exposes automated behavior, realized by application functions or interactions.

Data Object

A data object is a passive element suitable for automated processing, such as a customer record or a client database.

Technology Layer Meta-Model

The Technology layer meta-model includes concepts such as nodes, devices, system software, communication paths, and networks. These concepts help model the active structure and behavior of the technology layer.

Node

A node is a computational resource upon which artifacts may be stored or deployed for execution, such as a server or a network device.

Device

A device is a hardware resource upon which artifacts may be stored or deployed for execution, such as a physical server or a storage device.

System Software

System software is an infrastructural software component running on a device, such as an operating system or a database management system.

Communication Path

A communication path is a relation between two or more nodes through which they can exchange information, such as a network connection or a communication protocol.

Network

A network is a physical communication medium between two or more devices or other networks, such as a local area network (LAN) or a wide area network (WAN).
