   • Describes business services, processes, actors, and roles.
   • Emphasizes the customer-facing aspects of the organization.
2. Application Layer:
   • Deals with the application landscape that supports business functions.
   • Describes application services, components, and their interactions.
   • Provides insights into the software architecture of the organization.
3. Technology Layer:
   • Addresses the technology infrastructure necessary for applications.
   • Describes technological services, hardware, and system software.
   • Encompasses processing, storage, and communication services.
4. Motivation Layer:
   • Focuses on the drivers, goals, and principles guiding the organization.
   • Describes stakeholders, their concerns, and the assessment of strategic goals.
   • Provides a high-level view of why certain architectural decisions are made.
5. Strategy Layer:
   • Covers the approach and resources needed to bring about change.
   • Describes the engagement strategy and the required human and material resources.
   • Offers a roadmap for executing the strategic vision.
6. Physical Layer:
   • Extends the Technology layer by introducing physical elements.
   • Models tangible entities such as equipment, materials, and distribution networks.
   • Provides a bridge between the digital and physical aspects of the organization.
7. Implementation & Migration Layer:
   • Focuses on the temporal dimension of enterprise architecture.
   • Enables modeling of project and portfolio management.
   • Includes features for gap analysis, transition, and migration planning.

Each layer in the ArchiMate® standard contributes to a holistic understanding of the enterprise, allowing architects and stakeholders to articulate and visualize various facets of the organization’s architecture. The layers are interconnected, reflecting the interdependencies and relationships that exist within a complex business environment.

The components of the ArchiMate® standard:

1. Motivation:
   • Stakeholders: Individuals or groups with interests and concerns in the enterprise.
   • Drivers for Change: External or internal factors motivating changes in the organization.
   • Business Objectives: High-level goals that guide the organization.
   • Principles: Fundamental guidelines influencing decision-making.
   • Requirements: Specifications detailing what the system or solution must achieve.
2. Behavior:
   • Processes: Sequences of activities or tasks that lead to a specific outcome.
   • Functions: Units of activity with a specific purpose within the organization.
   • Events: Points in time or conditions that trigger processes or behaviors.
   • Services: Actions or functions offered by components to achieve specific outcomes.
3. Active Structure:
   • Company Actors: Entities within the organization that exhibit behavior and perform roles.
   • Application Components: Elements in the application layer that actively contribute to functionality.
