Overview

The Technology Domain represents the technical components and infrastructure that enable business operations. This domain focuses on applications, services, infrastructure elements, and technology standards that support organizational capabilities and business processes. It aligns with TOGAF's Technology Architecture while maintaining compatibility with the Orthogramic schema approach.

Purpose and Value

The Technology Domain enables organizations to:

Map technology components to business capabilities and strategic objectives
Document technical services and their relationships to business services
Analyze technology infrastructure to ensure it meets operational requirements
Establish and manage technology standards for consistency and interoperability
Support data-driven decision making about technology investments and priorities
Enable technology portfolio management and lifecycle planning
Provide a structured foundation for technology governance and risk management

Core Concepts

Application Component

A software application or system that provides specific functionality to support business operations. Application components are typically discrete software elements that can be deployed independently but may interact with other components.

Technology Service

A defined technical function or capability provided by technology components that can be consumed by other technology components, applications, or business processes. Technology services represent the operational capabilities provided by technology.

Technology Infrastructure

The foundational hardware, networks, platforms, and environments that support applications and services. Infrastructure elements represent the physical and virtual technology assets that enable all other technology operations.

Technology Standard

A formal specification, requirement, or approved approach for technology implementation, integration, or management. Standards ensure consistency, interoperability, and compliance across the technology landscape.

Conclusion

The Technology Domain extends the Orthogramic Metamodel with a comprehensive framework for modeling and managing the technical components that enable business operations. By providing structured schemas for applications, technology services, infrastructure, and standards, it enables organizations to systematically align their technology landscape with strategic objectives and operational requirements.

The integration with the Strategic Response Model ensures that technology insights drive strategic decision-making and organizational change. This domain complements other domains by focusing on the technical foundation that supports organizational activities, providing critical context for strategic planning and operational execution.

Organizations can use this domain to develop a more comprehensive understanding of their technology ecosystem, identify optimization opportunities, and ensure that technology investments are properly aligned with business needs and strategic priorities. The domain's alignment with TOGAF's Technology Architecture component enables organizations to leverage established enterprise architecture methods while maintaining compatibility with the Orthogramic schema approach.

TOGAF Integration Points

This domain would include specific mappings to TOGAF concepts:

Alignment with TOGAF's Technology Architecture component
Support for TOGAF's Architecture Development Method (ADM)
Compatibility with TOGAF's content metamodel
Support for TOGAF's building blocks approach

Schema Evolution Guidance

The Technology Domain schema is expected to evolve with emerging practices in technology management. Future extensions may include:

Cloud architecture frameworks
DevOps and continuous delivery models
Artificial intelligence and machine learning capabilities
Edge computing and distributed architectures
API and integration platforms
Cybersecurity frameworks and zero trust models

Organizations should plan for these evolutions by maintaining clean taxonomies and clear relationship models in their current implementation.
