The Myth of Specialized Architectures
For decades, IT architecture has been misunderstood and fragmented into specialized domains like Security Architecture, Network Architecture, and Data Architecture. These terms, while signifying essential areas of focus, have been misleadingly presented as comprehensive architecture. In reality, they represent specializations within architecture, not architecture itself.
This is as absurd as defining architecture by the materials used rather than the blueprint. Similarly, IT architecture must integrate all facets of an enterprise through a unified blueprint, not just isolated configurations.
The Problem: Specializations Mistaken for Architecture
1. Fragmented Understanding
Specialized architectures often focus on specific technologies or configurations, such as firewalls, switches, or databases.
This siloed approach results in disconnected decisions that ignore interdependencies across the broader enterprise system.
2. Lack of Holistic Perspective
True architecture considers how security, network, or data decisions align with:
Business goals
Processes
System interactions
Component Specifications
Implementation plans
Operations
Specialized architectures often fail to address these broader perspectives, limiting their strategic value.
Specialized approaches rarely address these questions, limiting their strategic value.
3. Focus on Configuration Over Strategy
For instance:
Security Architecture becomes a checklist of tools like firewalls or access controls without considering how they support compliance, data governance, or scalability.
Data Architecture becomes a conversation about configuring Oracle databases or designing ETL pipelines, missing how data aligns with workflows or supports decision-making.
True Architecture: Beyond Specializations
The ICMG Product Anatomy Model provides a comprehensive framework for defining true architecture. It spans six perspectives and six variables for each perspective, ensuring that systems align holistically with business goals.
Six Perspectives of Architecture:
Goals/Strategy Perspective
How does the architecture align with the enterprise's business objectives?
Business/Process Perspective
What workflows and processes does it enable or optimize?
System/Models Perspective
How do systems interact to deliver functionality?
Technology/Components Perspective
What tools, technologies, and components are required to implement the systems?
Implementation Perspective
How are systems, components, and processes deployed?
Operations Perspective
How are systems maintained, scaled, and monitored over time?
Why Specialized Architectures Fall Short
Security Architecture
Typical Focus: Configuring firewalls, encryption, or access controls.
Missed Opportunities: Rarely integrates security with workflows, regulatory goals, or system adaptability.
Network Architecture
Typical Focus: Setting up switches, routers, and connections.
Missed Opportunities: Ignores how networks impact end-user interfaces, workflows, or system models.
Data Architecture
Typical Focus: Designing ETL pipelines or configuring data warehouses.
Missed Opportunities: Fails to consider how data flows support business operations or decision-making.
What True Architecture Looks Like
Let’s use Data Architecture as an example:
Specialized Focus:
Configuring databases, ETL pipelines, or data warehouses.
True Architecture Focus:
Goals/Strategy: How does data enable faster decision-making and support business objectives?
Processes: How does data flow through workflows like supply chain management or customer analytics?
Systems: How do databases integrate with APIs, analytics platforms, and operational tools?
Technology/Components: What tools (e.g., Oracle, Snowflake) are required, and how are they integrated?
Implementation: What is the phased plan for deploying and scaling these systems?
Operations: How is data monitored, secured, and governed over time for various business decisions?
This approach ensures that data architecture is not about individual configurations but about aligning data systems holistically with the enterprise.
The Danger of Mislabeling Specializations as Architecture
1. Creates Silos
Isolated decisions lead to disconnected systems that fail to meet enterprise needs holistically.
2. Missed Opportunities
Without cross-perspective alignment, organizations miss chances to innovate, optimize workflows, or align with business goals.
3. Reactive, Not Strategic
Decisions focus on immediate needs, like configuring tools, instead of creating scalable, adaptable designs.
4. Increased Costs
Fragmented designs result in inefficiencies, technical debt, and higher integration costs.
Lessons from the Foundation of IT Architecture
Architecture Is a Blueprint, Not a Tool - Just as the architecture of a building isn’t defined by steel or cement brands, IT architecture isn’t defined by firewalls, databases, or networks. It’s the blueprint that aligns systems with business goals.
The Unified Anatomy Concept - Every enterprise system has a single, unified anatomy that integrates its structure, processes, systems, and operations. Specialized areas, like security or network configurations, are only pieces of this larger whole.
True Architecture Manages Complexity - Specialized architectures focus on managing individual elements, but true architecture handles the complexity of aligning all perspectives to deliver long-term value.
A Note to Data, Network, and Security Architects: Expanding Your Impact
Your expertise and specialization in data, network, and security components form the foundational elements of enterprise functionality. Whether ensuring seamless data flow, building robust network infrastructures, or fortifying systems against security threats, your contributions are invaluable in keeping organizations running efficiently and securely.
To enhance your impact, consider aligning your specialization with the broader perspective of Enterprise Anatomy. In this approach, data, network, and security are not isolated silos but interconnected components within a larger enterprise system—similar to how blood vessels, the heart, and oxygen exchange work together within the circulatory system. Each component is essential, and their integration is what ensures the system’s overall effectiveness and health.
The "One Enterprise, One Anatomy" model emphasizes that every element, no matter how specialized, contributes to the enterprise's cohesion and success. Expanding your skill set to include perspectives like process flows, system logic, and multi-variable integration (e.g., data, rules, timing, and roles) enables you to design solutions that are not only efficient and secure but also seamlessly integrated across the organization.
Your expertise is the foundation of enterprise resilience. Connecting it to the complete anatomy of the enterprise unlocks opportunities to design systems that are adaptive, collaborative, and aligned with strategic goals, ensuring your work drives value far beyond your domain.
Specializations Are Components, Not Architecture
The concept of "One Enterprise, One Anatomy" by ICMG transforms architecture from fragmented configurations into a cohesive, strategic framework. Specialized terms like Security Architecture, Network Architecture, and Data Architecture signify critical domains, but they are not architecture.
True architecture, guided by the ICMG Enterprise Anatomy Model, integrates systems, processes, and goals into a single cohesive blueprint. It ensures organizations move beyond tools and configurations to build systems that are resilient, adaptable, and aligned with long-term business success.
The choice is clear: Are you configuring tools, or are you architecting for the future?
