This comprehensive guide introduces the fundamental concepts of ArchiMate, offering insights and examples to help you get started.

What is ArchiMate?

• Visual Language: ArchiMate is a visual language equipped with a set of default icons designed to describe, analyze, and communicate various aspects of Enterprise Architectures. Its visual nature makes it accessible and understandable for stakeholders across different domains.

• Enterprise Architecture: ArchiMate is tailored to describe and visualize different business domains and their interrelationships. It provides a structured approach to modeling the complexities of an enterprise.

• Complementary, Not a Replacement: ArchiMate is not intended to replace other modeling languages like BPMN (Business Process Model and Notation) or UML (Unified Modeling Language). Instead, it ensures consistency and coherence across all enterprise domains, complementing these languages.

• Open Standard: As an open and independent modeling language, ArchiMate is widely adopted and supported, making it a reliable choice for enterprise architecture.

• Complements TOGAF: ArchiMate complements the TOGAF (The Open Group Architecture Framework) standard, providing a visual notation for modeling architectures developed using TOGAF.

• Models of Models: The ArchiMate specification uses metamodels to express the concepts and structures of various aspects of the language, ensuring a robust and flexible framework for modeling.

Core Concepts and Structure

Core Framework

The ArchiMate Core Framework classifies elements into three layers (Business, Application, and Technology) and three aspects (Active Structure, Behavior, and Passive Structure). This framework provides a structured approach to modeling enterprise architectures.

Core Language

The ArchiMate Core Language defines the concepts necessary to model Enterprise Architecture, focusing on the following elements:

• Active Structure Elements: Represent entities capable of performing behavior, such as business actors, application components, and devices.

  • Example: In a retail company, an “Order Processing System” is an active structure element that handles customer orders.

• Behavior Elements: Describe the transactions or processes that occur between active and passive structure elements.

  • Example: The “Order Fulfillment Process” is a behavior element that outlines the steps involved in processing and delivering orders.

• Passive Structure Elements: Represent information or objects that are used or produced by behavior elements.

  • Example: “Customer Data” is a passive structure element that is accessed and updated during the order fulfillment process.

Layers

ArchiMate uses layers to provide different levels of abstraction within an enterprise. The three primary layers are:

• Business Layer: Depicts business services offered to customers, focusing on business processes, roles, and information flows.

  • Example: Modeling the customer support process, including roles like “Customer Service Representative” and services like “Issue Resolution.”

• Application Layer: Represents application services that support business processes, focusing on software applications and their interactions.

  • Example: Mapping the “Customer Relationship Management (CRM)” application and its interactions with other applications like “Inventory Management System.”

• Technology Layer: Models the infrastructure that supports applications, focusing on hardware, networks, and data centers.

  • Example: Illustrating the server infrastructure that hosts the CRM application, including network components and storage solutions.

Relationships

Relationships in ArchiMate define the connections between concepts, classified as structural, dependency, or dynamic. These relationships help illustrate how different elements interact within the architecture.

• Example: A “Realization” relationship shows how an application component realizes a business service, such as a CRM system supporting customer service processes.

Abstraction

ArchiMate uses abstraction to simplify complex systems, allowing modelers to focus on high-level views while maintaining the ability to delve into details as needed.

• Example: A high-level view of the order fulfillment process might abstract away the details of individual system interactions, focusing instead on the overall flow of activities.

ArchiMate Example

The diagram is a representation of the ArchiMate framework, illustrating how different elements across the Business, Application, and Technology layers interact within an enterprise architecture. It showcases the relationships between these layers, focusing on behavior, structure, and information aspects.

Here’s a detailed explanation of the key concepts and components depicted in the diagram:

Layers and Aspects

The diagram is organized into three main layers: Business, Application, and Technology. Each layer is further divided into three aspects: Behaviour, Structure, and Information (though Information is only explicitly shown in the Technology layer).

Business Layer

• Business Event: Represents an occurrence that has significance for the business. It can trigger a business process.

  • Example: A customer placing an order.

• Business Service: Represents a unit of functionality that is meaningful from the point of view of the environment.

  • Example: Customer support service.

• Business Process: A sequence of activities that achieve a specific outcome. It is triggered by a business event and performed by a business role.

  • Example: Order processing, from receipt to delivery.

• Business Role: Represents a responsibility for performing specific behavior, to which an actor can be assigned.

  • Example: Customer service representative.

• Business Actor: An entity that performs behavior, such as a person, organization, or system.

  • Example: A customer or a customer service department.

• Business Object: Passive elements that represent information used or produced by a business process.

  • Example: Customer data or order details.

• Business Interface: A point of access where a business service is made available to the environment.

  • Example: A customer service portal.

Application Layer

• Application Service: Represents a unit of functionality that is meaningful from the point of view of the environment and is exposed by an application component.

  • Example: An API for accessing customer data.

• Application Function: Represents a unit of functionality that is meaningful from the point of view of the application.

  • Example: A function within a CRM system that manages customer interactions.

• Application Component: A piece of application software that implements functionality.

  • Example: A CRM system or an inventory management system.

• Application Data: Information used or produced by an application component.

  • Example: Customer records stored in a database.

• Application Interface: A point of access where an application service is made available to the environment.

  • Example: An API endpoint for accessing application services.

Technology Layer

• Technology Service: Represents a unit of functionality that is meaningful from the point of view of the environment and is exposed by a technology device.

  • Example: A database service or a file storage service.

• Artifact: A physical piece of information that is used or produced in a software development process, or by deployment and operation of a system.

  • Example: A software library or a configuration file.

• Technology Device: A physical IT infrastructure device.

  • Example: A server or a network switch.

• Technology Network: A communication infrastructure.

  • Example: A local area network (LAN) or a wide area network (WAN).

• Technology Interface: A point of access where a technology service is made available to the environment.

  • Example: A network port or a database connection.

Relationships

• Realization: Indicates that a behavior element (e.g., a process) is realized by a structure element (e.g., an application component).

  • Example: A business process is realized by an application function.

• Association: A general relationship between elements, indicating a relevant connection.

  • Example: A business object is associated with a business process.

• Access: Indicates that a behavior element reads from or writes to a passive structure element.
