ArchiMate Next: Reimagining Enterprise Architecture for a New Era

“The future of enterprise architecture isn’t about more complexity—it’s about clarity, connection, and coherence.”
— The Open Group, ArchiMate Next Specification Snapshot 1 (Mid-2025)

The release of ArchiMate Next Specification Snapshot 1 in mid-2025 marks a pivotal turning point in the evolution of enterprise architecture (EA). As the anticipated precursor to ArchiMate 4.0, this groundbreaking update redefines how organizations model, communicate, and align their digital transformation journeys. More than a refinement, ArchiMate Next represents a philosophical and structural revolution—replacing outdated hierarchies with dynamic interconnectivity, simplifying complexity, and embracing the realities of modern hybrid enterprises.

This article explores the transformative changes introduced in ArchiMate Next, unpacking its core innovations, technical enhancements, and implications for practitioners, architects, and stakeholders across industries.

🔮 A Vision for the Future: Why ArchiMate Next?

For over a decade, ArchiMate 3.2 has served as the de facto standard for enterprise modeling. Yet, as digital transformation accelerates and organizations adopt AI, automation, and decentralized systems, the limitations of the traditional layered approach have become increasingly apparent:

  • Overly rigid layering that fails to reflect real-world interdependencies.

  • Redundant elements across layers (e.g., Business Process vs. Application Service).

  • Cognitive overload for new architects and non-specialists.

  • Poor alignment with hybrid human-AI ecosystems.

ArchiMate Next answers these challenges head-on. Its mission is clear: reduce cognitive friction while amplifying expressive power. It aims to make enterprise architecture more accessible, intuitive, and relevant—not just for seasoned architects, but for product owners, developers, business leaders, and even AI agents.

“We’re not just updating a language—we’re reimagining how we think about enterprise systems.”
— Dr. Elena Torres, Chief Architect, The Open Group

🌀 1. The Hexagonion: A Visual and Structural Revolution

From Layers to a Living Ecosystem

The most visible and profound change in ArchiMate Next is the replacement of the traditional rectangular layered matrix with the Hexagonion Framework—a radical departure from the “top-down” mindset that has defined EA for years.

The Hexagonion is not merely a new diagram style; it’s a paradigm shift in how we conceptualize enterprise architecture. It reflects the reality of today’s organizations: where humans, software, and AI collaborate at the same level, and where business, application, and technology domains are deeply intertwined.

Structure of the Hexagonion

Position Domain Purpose
Center Hub Core Building Blocks Active Structure, Behavior, Passive Structure — the foundational elements of all models
Top (Central Hexagon) Operational Core Merged domains: Business, Application, and Technology — unified into a single operational plane
Top Left & Right Strategy & Motivation Goals, Drivers, Requirements, Value Streams — the “why” behind enterprise actions
Bottom Left & Right Implementation & Migration Projects, Changes, Transitions, Deliverables — the “how” of transformation

Why the Hexagonion Matters

  • Eliminates top-down bias: No longer does the model imply that business “controls” applications, which in turn “control” technology.

  • Promotes holistic thinking: Encourages architects to view the enterprise as a network of interdependent actors and processes.

  • Supports hybrid environments: Enables seamless modeling of human-AI collaboration, where AI services behave like any other active structure.

  • Improves stakeholder engagement: The symmetrical, balanced layout is more intuitive and visually engaging for non-technical audiences.

💡 Insight: Early adopters report that the Hexagonion has already improved cross-functional workshops—executives grasp the model faster, and developers see their roles in context.

🔗 2. Unification of Core Concepts: Breaking Down Silos

ArchiMate Next boldly dismantles the artificial boundaries between layers. Instead of layer-specific elements, the language now embraces domain-agnostic modeling, promoting consistency and reducing duplication.

Unified Behavior Elements

No more “Business Process” vs. “Application Service.” In ArchiMate Next, behavior is behavior—regardless of layer.

The new generic behavior types are:

Element Description
Service A capability offered to others (e.g., a payment service, an AI inference engine)
Process A sequence of activities that achieve a purpose (e.g., onboarding a customer)
Function A defined responsibility or role (e.g., “Risk Assessment”)
Event A significant occurrence that triggers behavior (e.g., “System Alert”, “User Login”)

These elements can be applied across any domain—a Business Function can be performed by a human, a software component, or an AI agent.

✅ Example: A “Customer Onboarding Process” can include:

  • A Human Role (Customer Service Agent),

  • An AI Function (Document Verification),

  • A Software Service (CRM Integration),

  • All connected via a single Process element.

Generic Role: The Democratization of Identity

The concept of “Business Role” is replaced by a generic Role in the Common Domain.

  • Roles are now assigned to any Active Structure, including:

    • Human actors

    • Software components

    • AI models

    • Hardware devices

This enables richer modeling of delegation, responsibility, and accountability across hybrid teams.

🛠️ Use Case: In a smart factory, an AI model can be assigned the Role of “Quality Inspector”, just like a human worker—making the model’s function explicit and traceable.

Unified Collaboration: One Way to Model Interaction

All cross-layer interactions are now modeled using a single Collaboration element.

  • Replaces:

    • Business Collaboration

    • Application Collaboration

    • Technology Collaboration

This simplifies the metamodel and reflects reality: interactions don’t care about layers. A user interacting with a chatbot, a system calling an API, or a team sharing a document—all are forms of collaboration.

✅ Benefit: Architects no longer need to decide which “type” of collaboration to use—just model the interaction.

🧼 3. Cutting the Metamodel Clutter: Simplicity by Design

ArchiMate Next isn’t about adding features—it’s about removing noise. The team at The Open Group conducted extensive analysis of real-world models and found that many elements were rarely used, poorly understood, or caused confusion.

Elements Removed (and Why)

Removed Element Replacement Rationale
Composition Relationship Aggregation or Assignment Often confused with aggregation; redundant when assignment suffices
Business/Application/Technology Interaction Collaboration or Service Redundant; all interactions are now unified
Constraint Requirement (specialized) Constraints are a form of requirement; better modeled as such
Contract Agreement (specialized) Merged into broader contractual relationships
Gap Assessment or Deliverable Gaps are outcomes of assessments, not standalone entities
Representation Artifact or Document Redundant with existing passive structure elements

🚫 No more “Which layer does this go in?”
With fewer elements and clearer semantics, modeling becomes faster and more intuitive.

🛠️ 4. Metamodel Enhancements: Precision Without Complexity

Beyond simplification, ArchiMate Next introduces subtle but powerful enhancements that improve semantic precision and model integrity.

Cardinalities on Relationships

One of the most anticipated features: multiplicities (cardinalities) can now be specified on relationships.

  • Example: A Service may have 0..* (zero to many) Consumers

  • A Process may involve 1..1 (exactly one) Owner Role

This allows architects to express instance-level constraints directly in the model—critical for integration, compliance, and system design.

✅ Impact: No more guessing how many instances of a service exist—this is now explicit and verifiable.

Path Element: Reimagined and Re-located

The Path element—previously aggregated from a technology component—has been moved to the Common Domain.

  • New Relationship: A Realization relationship links an Active Structure (e.g., a Service) to a Path (e.g., a data flow, API route, or workflow path).

  • This better reflects that a path is realized by a structure, not owned by it.

🔄 Before: Technology Component → Path (aggregation)
After: Service → Path (Realization)

This change improves model accuracy and supports traceability in complex systems.

Standardization for Interoperability

To ensure consistency across tools and teams:

  • RGB color codes are now standardized (e.g., Business = #2E8B57, Technology = #00008B)

  • Viewpoint mechanisms follow a unified pattern

  • Naming conventions and iconography are aligned across vendors

✅ Result: Models created in one tool can be seamlessly interpreted in another—no more “translation” headaches.

🔄 5. Backward Compatibility and Migration Path

The Open Group has prioritized smooth transition from ArchiMate 3.2 to ArchiMate Next. Most existing models can be migrated with minimal effort—especially those using core concepts.

Migration Guide: From 3.2 to Next

ArchiMate 3.2 Element ArchiMate Next Replacement Notes
Composition Aggregation or Assignment Use aggregation for part-of relationships; assignment for ownership
Business Interaction Collaboration or Service Choose based on intent: collaboration = interaction, service = capability
Constraint Requirement (with stereotype) Add constraint stereotype to clarify intent
Gap Assessment or Deliverable Model gaps as outcomes of assessments
Implementation Event Generic Event Use Event with appropriate context (e.g., “System Upgrade”)

🛠️ Tool Support: Major EA tools (e.g., Sparx EA, Archi, LeanIX, ServiceNow EA) are already developing migration plugins. A free ArchiMate Next Converter Tool will be released in Q3 2025.

🌍 Community Perspective: Excitement, Caution, and Opportunity

Early feedback from the EA community has been overwhelmingly positive—but with thoughtful caveats.

✅ What Practitioners Love

  • “The Hexagonion is a game-changer.”
    — James Lin, Enterprise Architect, Global Retailer

  • “I can now model AI agents the same way I model humans. It finally makes sense.”
    — Dr. Amina Patel, AI & EA Lead, Financial Services

  • “The simplified metamodel means less training time and faster onboarding.”
    — Maria Chen, EA Consultant, Digital Transformation Firm

⚠️ Constructive Concerns

  • Loss of Layer-Specific Nuance?
    Some experts warn that unifying behavior across layers might obscure critical distinctions in large, complex systems—especially where business logic differs fundamentally from application logic.

  • Risk of Oversimplification?
    “We must be careful not to lose the depth that made ArchiMate powerful,” cautions Thomas Reed, Lead EA at a Defense Contractor. “Unification is great—but we still need ways to express architectural intent at scale.”

✅ The Open Group Response: ArchiMate Next is not a one-size-fits-all model. It provides a common foundation, but advanced modeling is still possible through stereotypes, viewpoints, and extensions.

📌 Conclusion: A New Era for Enterprise Architecture

ArchiMate Next is more than a specification update—it’s a rebirth of enterprise architecture.

It answers the call for:

  • Simpler models that are easier to learn and communicate.
