TOGAF 10 Foundation: Requirements Management and the ADM Cycle

TOGAF 10 Foundation: Requirements Management and the ADM Cycle

Why Requirements Management is Important

Requirements Management is a critical discipline in enterprise architecture that ensures organizational needs are properly captured, analyzed, prioritized, and traced throughout the Architecture Development Method (ADM) cycle. Its importance lies in:

• Alignment: Ensures architecture decisions align with business objectives and stakeholder expectations
• Traceability: Maintains clear linkage between business requirements and architecture solutions
• Change Control: Manages how requirements evolve and impact architecture deliverables
• Risk Mitigation: Identifies gaps and conflicts early in the process
• Stakeholder Satisfaction: Ensures all stakeholder needs are documented and addressed
• Quality Assurance: Validates that implemented solutions meet intended requirements

What is Requirements Management?

Requirements Management in TOGAF is the continuous process of identifying, analyzing, documenting, and managing requirements throughout the ADM cycle. It is not a separate phase but rather a continuous activity that runs parallel to all ADM phases.

Key characteristics include:

• Requirements come from multiple sources: business stakeholders, IT teams, regulatory bodies, and other stakeholders
• Requirements are captured in a structured format with clear definitions
• Requirements are prioritized based on business value and strategic importance
• Requirements are traced to architecture components and solutions
• Requirements management includes handling changes and impacts throughout the project lifecycle

The ADM Cycle Context

The ADM cycle consists of nine phases:

• Phase A: Architecture Vision - Establishes business requirements and high-level architecture objectives
• Phase B: Business Architecture - Details business processes and identifies business-related requirements
• Phase C: Information Systems Architecture - Addresses data and application requirements
• Phase D: Technology Architecture - Identifies technology platform requirements
• Phase E: Opportunities & Solutions - Consolidates requirements into implementation roadmaps
• Phase F: Migration Planning - Addresses requirements for transition activities
• Phase G: Implementation Governance - Manages requirements during implementation
• Phase H: Architecture Change Management - Handles requirement changes post-implementation
• Requirements Management (RMg): Continuous activity supporting all phases

How Requirements Management Works in the ADM Cycle

1. Requirements Identification

Requirements are identified from various sources throughout the ADM cycle:

• Business strategy and goals
• Stakeholder interviews and workshops
• Process analysis and modeling
• Current system assessment
• Regulatory and compliance requirements
• Technical constraints and opportunities

2. Requirements Documentation

Each requirement should be documented with:

• Requirement ID: Unique identifier for traceability
• Description: Clear statement of what is needed
• Source: Where the requirement originated
• Priority: Business importance and urgency
• Status: Current state (proposed, approved, implemented)
• Related Requirements: Links to dependent requirements
• Acceptance Criteria: How to verify the requirement is met

3. Requirements Analysis

Requirements are analyzed to:

• Identify conflicts and dependencies
• Assess feasibility and impact
• Determine resource needs
• Evaluate against architectural principles
• Prioritize based on business value

4. Requirements Traceability

Create and maintain traceability matrices linking:

• Business requirements to IT requirements
• Requirements to architecture components
• Architecture components to implementation solutions
• Requirements to test cases
• Requirements to deployment activities

5. Requirements Management Throughout ADM Phases

• Phase A & B: Capture business and functional requirements
• Phase C & D: Decompose requirements into system and technical specifications
• Phase E: Map requirements to solutions and roadmaps
• Phase F & G: Ensure requirements drive transition planning and governance
• Phase H: Manage changes to requirements and their impact

6. Change and Impact Management

When requirements change:

• Assess impact on architecture and implementation
• Evaluate resource and timeline implications
• Obtain appropriate approval
• Update affected architecture artifacts
• Communicate changes to stakeholders
• Update traceability matrices

How Requirements Management Integrates with ADM

Requirements Management is a continuous thread through the entire ADM cycle:

• Initial Definition: Requirements are first identified in Phase A (Architecture Vision)
• Progressive Elaboration: Requirements are detailed and refined in each subsequent phase
• Validation: Requirements are continuously validated against stakeholder expectations
• Management: Changes and impacts are managed throughout the lifecycle
• Closure: Requirements are verified as implemented in Phase H

Best Practices for Requirements Management in ADM

• Establish a Requirements Repository: Centralized system for storing and managing all requirements
• Define Clear Ownership: Assign responsibility for each requirement
• Create Traceability Matrix: Document relationships between all requirement types
• Regular Review Cycles: Periodically review and validate requirements with stakeholders
• Version Control: Track changes and maintain history of requirement evolution
• Stakeholder Engagement: Keep stakeholders involved throughout the requirements process
• Impact Analysis: Always assess the impact of changes before implementation
• Communication: Ensure clear communication of requirements status to all parties

Exam Tips: Answering Questions on Requirements Management and the ADM Cycle

Tip 1: Understand Requirements Management as a Continuous Activity

Questions often test whether you understand that Requirements Management (RMg) is not a separate ADM phase but rather a continuous activity that runs parallel to all phases. When answering, emphasize that requirements are managed throughout the entire ADM cycle, from initiation through change management.

Tip 2: Know the Flow of Requirements Through ADM Phases

Be prepared to explain how requirements flow through the ADM:

• Identified in Phase A (Architecture Vision)
• Detailed in Phases B, C, and D
• Consolidated in Phase E
• Implemented via Phases F and G
• Managed and changed in Phase H

Questions may ask how requirements from one phase inform the next phase.

Tip 3: Master Traceability Concepts

Exam questions frequently test understanding of requirements traceability. Key points to remember:

• Traceability ensures each requirement is linked to specific architecture components
• Traceability matrices show relationships between requirement types
• Impact analysis depends on good traceability
• Traceability helps ensure no requirements are lost or forgotten

Tip 4: Distinguish Between Requirement Types

Be able to identify and differentiate:

• Business Requirements: What the business needs to achieve
• Functional Requirements: What the system must do
• Non-Functional Requirements: System properties (performance, security, usability)
• Technical Requirements: How systems must be implemented
• Compliance Requirements: Regulatory and standards compliance

Tip 5: Understand Change Management Integration

Questions about requirements often touch on change management. Remember:

• Phase H (Architecture Change Management) is where requirement changes are formally managed
• Impact analysis is critical before accepting requirement changes
• Approved changes must be traced through the architecture
• Stakeholder communication is essential when requirements change

Tip 6: Know the Requirements Management Process

Be familiar with the standard process flow:

1. Identify requirements from multiple sources
2. Document requirements with clear attributes
3. Analyze requirements for feasibility and conflicts
4. Prioritize requirements based on value
5. Create traceability links
6. Manage changes and impacts
7. Verify and validate implementation

Tip 7: Connect Requirements to Stakeholder Concerns

Requirements Management directly addresses stakeholder concerns and viewpoints. When answering questions:

• Reference the stakeholder community that the requirement serves
• Explain how requirements management ensures stakeholder satisfaction
• Discuss how conflict resolution works when stakeholders have competing requirements

Tip 8: Recognize Requirements Management Tools and Artifacts

Familiarize yourself with outputs of Requirements Management:

• Requirements repository or database
• Traceability matrices
• Requirements specifications documents
• Impact analysis reports
• Change request logs
• Requirements status dashboards

Tip 9: Answer Pattern Recognition

Look for these clue words in exam questions:

• "Throughout the ADM" - Suggests Requirements Management as continuous activity
• "Traceability" - Focuses on linking requirements to architecture
• "Impact of change" - Related to Phase H and change management
• "Stakeholder requirements" - Focus on identifying and managing stakeholder needs
• "Requirements validation" - Ensuring requirements are met by solutions

Tip 10: Practice with Scenario Questions

Exam scenarios often present a situation like: "A new business requirement has emerged during Phase D. What should happen?"

Your answer should address:

• Requirements change management process should be invoked
• Impact analysis must be performed
• Affected architecture artifacts must be updated
• Traceability must be maintained
• Stakeholders must be informed
• Timeline and resource implications must be assessed

Tip 11: Distinguish ADM Cycle from Requirements Management

Questions may ask the difference. Remember:

• The ADM Cycle has nine phases (A-H and RMg) that provide methodology for developing architecture
• Requirements Management is one continuous activity within the ADM Cycle that runs throughout all phases
• The ADM is sequential with iteration; Requirements Management is parallel and ongoing

Tip 12: Relate to TOGAF Architecture Content Framework (AFC)

Requirements Management connects to the AFC:

• Business Architecture artifacts capture business requirements
• Information Systems Architecture captures data and application requirements
• Technology Architecture captures technology requirements
• Requirements Management ensures all AFC artifacts are tied to actual business requirements

Sample Exam Question Approaches:

Question Type 1: "When should requirements be managed?"
Answer: Throughout the entire ADM cycle, from Phase A through Phase H, as a continuous parallel activity

Question Type 2: "What is the purpose of requirements traceability?"
Answer: To maintain clear links between business requirements and architecture components/solutions, enabling impact analysis and validation

Question Type 3: "How does Requirements Management relate to Phase H?"
Answer: Phase H (Architecture Change Management) formally manages requirement changes post-implementation, but Requirements Management concepts apply throughout all phases

Question Type 4: "Which phase identifies business requirements?"
Answer: Phase A (Architecture Vision) initiates requirements identification, with detailed business requirements captured in Phase B

Question Type 5: "What should happen when a requirement changes during implementation?"
Answer: Impact analysis is performed, change control process is invoked, affected artifacts are updated, traceability is maintained, and stakeholders are communicated with

Final Exam Strategy

When answering Requirements Management questions:

• Always emphasize the continuous nature of Requirements Management across all ADM phases
• Reference traceability as a key requirement management concept
• Connect requirements to stakeholder concerns and viewpoints
• Explain how requirements flow and evolve through the ADM
• Demonstrate understanding of impact analysis for changes
