Agile and the ADM: Complete Guide for TOGAF 10 Foundation

Why Is Agile and the ADM Important?

In today's rapidly changing business environment, organizations need to adapt quickly to new market demands, technological innovations, and competitive pressures. The traditional waterfall approach to architecture development, while structured, can be too rigid and slow for modern enterprises.

The importance of understanding Agile and the ADM lies in:

• Flexibility: Agile methodologies allow organizations to respond quickly to changing requirements and market conditions.
• Iterative Delivery: Organizations can deliver value incrementally rather than waiting for a complete architecture deliverable.
• Stakeholder Engagement: Agile practices emphasize continuous collaboration with stakeholders, ensuring architecture remains aligned with business needs.
• Risk Reduction: Early and frequent feedback helps identify and mitigate risks sooner in the development cycle.
• Competitive Advantage: Organizations can bring products and services to market faster.
• Modern Enterprise Reality: Many organizations are adopting Agile development practices, so architects must understand how to support and work within these frameworks.

What Is Agile and the ADM?

The Architecture Development Method (ADM) is TOGAF's core process for developing enterprise architecture. It provides a detailed, step-by-step approach to creating and managing enterprise architecture across all domains (Business, Data, Application, Technology).

Agile and the ADM refers to the adaptation and application of Agile principles and practices to the ADM framework. Rather than viewing the ADM as a purely sequential, waterfall-style methodology, Agile and the ADM demonstrates how to apply iterative, incremental approaches to architecture development.

Key Agile Principles in the Context of ADM:

• Iterative Development: The ADM phases are executed iteratively in smaller cycles rather than one complete end-to-end cycle.
• Incremental Delivery: Architecture deliverables are produced and refined in increments, providing value sooner.
• Continuous Feedback: Regular stakeholder engagement and feedback loops are built into each iteration.
• Adaptive Planning: Plans and requirements evolve based on feedback and changing business conditions.
• Cross-Functional Collaboration: Architects work closely with development teams, business stakeholders, and other teams throughout the process.
• Responding to Change: Architecture development embraces and accommodates change rather than resisting it.

How Does Agile and the ADM Work?

Understanding the Mechanics:

While the traditional ADM follows a linear progression through phases (Preliminary, A, B, C, D, E, F, G, H), Agile and the ADM applies these phases in a more flexible, iterative manner:

1. Iterative Cycles

Instead of completing each ADM phase once, organizations using Agile approaches execute multiple short cycles, each passing through relevant ADM phases. Each cycle produces working architecture artifacts and can be demonstrated to stakeholders.

2. Time-Boxed Iterations

Work is organized into fixed time periods (sprints, typically 2-4 weeks), similar to Agile software development practices. This keeps focus and provides regular opportunities to assess progress.

3. Incremental Architecture Definition

Rather than defining the complete architecture before implementation begins:

• Start with a high-level architecture vision and roadmap
• Develop detailed architecture components in increments
• Each increment addresses a specific business capability or value stream
• Refine and adjust architecture based on implementation feedback

4. Stakeholder Collaboration

Agile ADM emphasizes:

• Regular architecture review sessions with stakeholders
• Quick feedback loops to ensure architecture remains relevant
• Transparent communication of architecture decisions and rationale
• Active involvement of business and technical stakeholders throughout

5. Continuous Planning and Adjustment

As new information emerges through implementation and stakeholder feedback, the architecture roadmap and detailed designs are adjusted. This represents a shift from plan-driven to adaptive architecture development.

6. Integration with Development Teams

Unlike traditional approaches where architects complete all work before handing off to developers, Agile ADM involves:

• Architects working alongside development teams
• Architecture evolving through development sprints
• Quick resolution of architecture-related questions during development
• Regular synchronization between architecture and implementation

Applying Agile and the ADM in Practice

Practical Implementation Steps:

Phase 0 (Preliminary)

Complete foundational activities but keep initial scope limited. Identify the first value stream or business capability to focus on initially.

Phase A (Architecture Vision)

Create a preliminary vision and identify the first iteration scope. This may address only a portion of the full enterprise initially.

Phases B, C, D (Business, Information Systems, Technology Architecture)

Execute these phases in an iterative manner:

• First iteration: Define architecture for the initial business capability or value stream
• Subsequent iterations: Expand coverage, refine designs based on feedback
• Each iteration produces working deliverables that can be reviewed

Phase E (Opportunities and Solutions)

Identify solution components needed for the current iteration, not necessarily all solutions for the entire enterprise architecture.

Phase F (Migration Planning)

Create a migration roadmap that aligns with iterative delivery. Plan implementation in increments.

Phase G (Implementation Governance)

Establish governance that supports iterative delivery while maintaining architecture integrity.

Phase H (Architecture Change Management)

Implement change management processes that can handle frequent updates to architecture as iterations progress.

Key Differences: Traditional ADM vs. Agile ADM

Exam Tips: Answering Questions on Agile and the ADM

Understanding the Core Concept

Remember that Agile and the ADM does not mean replacing the ADM with Agile. It means adapting how the ADM is executed to incorporate Agile principles. The ADM phases remain the same; their application becomes more iterative and incremental.

Key Points to Emphasize in Exam Answers:

• Iterative Application: Clearly state that the ADM phases are applied in multiple shorter iterations rather than one long sequential cycle.
• Value Delivery: Highlight that each iteration produces tangible, demonstrable value to stakeholders.
• Continuous Feedback: Mention regular stakeholder engagement and feedback loops as essential components.
• Flexibility: Emphasize the ability to adapt architecture as new information emerges and business needs change.
• Team Collaboration: Stress that architects work closely with development teams and other stakeholders throughout the process.
• Scope Management: Explain how iterative approaches allow for more focused, manageable scope in each iteration.

Common Exam Question Types and How to Answer Them:

Question Type 1: "What is the primary benefit of Agile and the ADM?"

Good Answer Structure: Start with the main benefit (faster value delivery, better stakeholder alignment, or flexibility), then provide supporting details about how this benefits the organization. For example:

"The primary benefit of Agile and the ADM is the ability to deliver architectural value incrementally and respond quickly to changing business requirements. Rather than waiting months or years for a complete architecture, organizations can deploy value in shorter iterations, gather feedback, and adjust the architecture accordingly. This reduces time-to-market and keeps architecture aligned with evolving business needs."

Question Type 2: "How does Agile and the ADM differ from traditional ADM?"

Good Answer Structure: Use a comparison approach, contrasting key aspects:

"Traditional ADM follows a sequential approach where all ADM phases are completed once in a linear fashion. Agile and the ADM applies the same phases iteratively in shorter cycles. In traditional ADM, the complete architecture is defined before implementation begins, while in Agile ADM, architecture is developed incrementally alongside implementation. Traditional ADM uses periodic stakeholder reviews, while Agile ADM emphasizes continuous collaboration. This makes Agile ADM more flexible and responsive to change."

Question Type 3: "Describe how iterations work in Agile and the ADM."

Good Answer Structure: Explain the cyclical nature and what happens in each cycle:

"In Agile and the ADM, iterations are typically short (2-4 weeks) time-boxed cycles. Each iteration passes through relevant ADM phases—the organization might focus on a specific business capability or value stream. During each iteration, architects define vision (Phase A), develop business, information systems, and technology architectures (Phases B, C, D), identify solutions (Phase E), and plan implementation (Phase F). Each iteration produces working architecture artifacts that are reviewed with stakeholders. Based on feedback, the next iteration refines or expands the architecture. This continues until the desired scope is covered or business priorities shift."

Question Type 4: "Which ADM phases are skipped or modified in Agile ADM?"

Good Answer Structure: Clarify that no phases are skipped, but their application changes:

"No ADM phases are skipped in Agile and the ADM. All phases—Preliminary through H—still apply. However, their execution is modified. Instead of completing each phase once for the entire enterprise, the organization executes phases iteratively and incrementally, focusing on specific value streams or business capabilities in each iteration. For example, Phase A (Architecture Vision) establishes the overall vision once, then each iteration focuses on specific Phases B, C, and D activities for the current iteration scope. This distributed approach across multiple iterations is the key modification."

Question Type 5: "What role do stakeholders play in Agile and the ADM?"

Good Answer Structure: Emphasize continuous engagement:

"Stakeholders play a continuous and active role in Agile and the ADM. Unlike traditional approaches with periodic reviews, Agile ADM requires regular stakeholder engagement throughout each iteration. Stakeholders participate in iteration planning to understand scope, provide feedback on architecture decisions during development, review working deliverables, and help prioritize what's addressed in subsequent iterations. This continuous collaboration ensures the architecture remains aligned with business needs and reduces the risk of misalignment between architecture and business objectives."

Question Type 6: "How is risk managed in Agile and the ADM?"

Good Answer Structure: Highlight continuous identification and mitigation:

"In Agile and the ADM, risk management is continuous rather than a one-time activity. Risks are identified early in each iteration and addressed through architectural decisions and implementation. The short iteration cycles allow risks to surface quickly and be mitigated before they escalate. Regular stakeholder feedback helps identify business risks related to the architecture. Failed experiments or prototypes in early iterations reveal technical risks without derailing the entire architecture initiative. This continuous risk identification and mitigation reduces overall project risk compared to traditional approaches where issues may not surface until late in the project."

Exam Strategy and Common Pitfalls

What Examiners Are Looking For:

• Correct Terminology: Use "Agile and the ADM" or "Agile approaches to ADM" - not "Agile ADM" as a replacement methodology.
• Iterative Understanding: Demonstrate that you understand the iterative nature - this is the core concept.
• ADM Knowledge: Show that you still understand the traditional ADM phases and how they apply, just in a modified way.
• Practical Application: Give concrete examples of how this would work in real organizations.
• Benefits Articulation: Clearly explain why organizations would choose this approach.

Common Pitfalls to Avoid:

• Pitfall 1: "Agile and the ADM replaces the traditional ADM."
  Correction: Agile and the ADM is an adaptation of how the ADM is applied, not a replacement of the ADM itself.
• Pitfall 2: "In Agile ADM, architects don't plan the architecture upfront."
  Correction: Phase A still establishes an overall vision and roadmap; what changes is that detailed architecture is developed iteratively rather than all upfront.
• Pitfall 3: "Agile and the ADM means no documentation."
  Correction: Documentation is still created, but it's produced incrementally across iterations and focuses on what's necessary rather than comprehensive upfront documentation.
• Pitfall 4: "Stakeholders are less involved in Agile and the ADM."
  Correction: Stakeholders are actually MORE involved with continuous engagement rather than periodic reviews.
• Pitfall 5: "Agile ADM eliminates governance."
  Correction: Governance is still essential; it's adapted to support iterative delivery while maintaining architecture integrity.

Structuring Your Answer:

When answering exam questions about Agile and the ADM, use this structure:

1. State the core concept clearly: "Agile and the ADM refers to applying Agile principles to the traditional ADM..."
2. Explain what changes: "Rather than sequential execution, the ADM phases are applied iteratively..."
3. Explain what remains constant: "The ADM phases themselves don't change..."
4. Provide a concrete benefit: "This approach allows organizations to deliver value faster and respond to changing requirements..."
5. Include an example if possible: "For instance, instead of spending six months defining the complete architecture, an organization might spend 2-3 weeks on each iteration focusing on one business capability..."

Exam Question Examples and Model Answers:

Example Question 1:

"Which of the following best describes how Agile principles are applied to the TOGAF ADM?"

A) The ADM phases are replaced with Agile sprints.
B) The ADM phases are applied iteratively in shorter cycles rather than sequentially.
C) Agile and the ADM eliminates the need for detailed architecture planning.
D) Stakeholder engagement is reduced to minimize meeting time.

Correct Answer: B
Explanation: This is the core concept. The ADM phases remain in place (ruling out A), detailed planning still occurs (ruling out C), and stakeholder engagement increases (ruling out D). The key difference is the application of these phases in shorter, iterative cycles.

Example Question 2:

"In an Agile and the ADM approach, what is the primary focus during the first iteration?"

A) Complete the entire enterprise architecture for all domains.
B) Define a complete migration plan for all business capabilities.
C) Establish the architecture vision and focus on a specific business capability or value stream.
D) Identify all risks and mitigation strategies before beginning development.

Correct Answer: C
Explanation: While Phase A establishes an overall vision for the enterprise, in an Agile approach, the first iteration focuses on a manageable scope—a specific business capability or value stream. This allows for incremental value delivery. Options A, B, and D suggest trying to complete too much in the first iteration.

Example Question 3:

"How does architecture change management differ between traditional ADM and Agile and the ADM?"

Model Answer: "In traditional ADM, architecture is relatively stable once defined, and changes go through formal change control to minimize disruption. In Agile and the ADM, change is expected and more frequent as the architecture evolves through iterations based on feedback and new information. Change management processes are still in place to maintain integrity, but they are designed to accommodate continuous refinement. Rather than viewing changes as problems to be prevented, Agile ADM treats them as normal and incorporates mechanisms to evaluate and implement them quickly. This reflects the adaptive nature of iterative development and the reality that requirements and business conditions continually evolve."

Final Preparation Tips

• Create a visual comparison chart: Draw a side-by-side comparison of traditional ADM vs. Agile ADM highlighting key differences. This helps cement the concepts in your mind.
• Practice explaining without documentation: Be able to explain Agile and the ADM in simple terms without referencing the TOGAF specification, as if teaching a colleague.
• Focus on the "why": Understand the business drivers for choosing Agile approaches - this context makes exam answers stronger.
• Remember iteration patterns: Most iterations follow a similar pattern through relevant ADM phases, with incrementally expanding scope.
• Link to real-world examples: Think about real organizations using Agile approaches and how they might apply the ADM iteratively - this helps with exam question scenarios.
• Review stakeholder engagement: This is often a focus area - be clear about the continuous collaboration aspect.
