The Architecture Development Method (ADM) phases and Stakeholder Management are heavily tested because they form the practical core of enterprise architecture work. Governance and Phase A (Architecture Vision) also receive significant coverage since they establish the foundation for any architecture engagement. Review these areas thoroughly and ensure you can apply them to realistic scenarios.
The ADM provides a repeatable cycle: Phase A defines the vision and scope, Phases B-D develop business and technology architectures, Phase E identifies opportunities, Phase F plans implementation, Phase G oversees delivery, and Phase H manages change. In practice, phases may overlap or iterate based on organizational needs. Understanding this flow helps you map architecture decisions to project timelines and stakeholder expectations.
Candidates often confuse the purpose of different ADM phases or misapply governance concepts to specific scenarios. Another frequent error is overlooking stakeholder management as a continuous activity rather than a one-time task. Review the phase objectives carefully and practice scenario questions that test your ability to select the correct phase or governance approach for a given situation.
Read the business context and stakeholder needs first, then identify which ADM phase or TOGAF concept applies. Look for keywords like "initial engagement" (Phase A), "competing requirements" (stakeholder management), or "post-implementation monitoring" (Phase H and change management). Eliminate answers that address the right topic but the wrong phase or context.
Focus on scenario-based practice questions and timed mini-tests rather than re-reading notes. Review your weak topic areas identified in earlier practice tests. Ensure you can quickly recall ADM phase names, governance principles, and reference model components. Get adequate sleep the night before the exam and arrive early to reduce stress.
Which of the following statements about architecture partitioning are correct?
1 Partitions are used to simplify the management of the Enterprise Architecture
2 Partitions are equivalent to architecture levels
3 Partitions enable different teams to work on different element of the architecture at the same time.
4 Partitions reflect the organization's structure
Statements 1 and 3 about architecture partitioning are correct. Architecture partitioning is the technique of dividing an architecture into smaller and more manageable parts that can be developed, maintained, and governed independently. Partitions are used to simplify the management of the Enterprise Architecture and to enable different teams to work on different elements of the architecture at the same time. Partitions are not equivalent to architecture levels, which are different degrees of abstraction or detail in an architecture. Partitions do not necessarily reflect the organization's structure, which may change over time or differ from the architecture's scope and boundaries. Reference: The TOGAF Standard | The Open Group Website, Section 2.5 Architecture Partitioning.
Which of the following best describes the need for the ADM process to be governed?
According to the TOGAF standard, the need for the ADM process to be governed is to ensure that the architecture development and implementation activities are conducted in a consistent, coherent, and compliant manner1. Governance provides the means to verify that the method is being applied correctly and effectively, and that the architecture deliverables and artifacts meet the quality and standards criteria1. Governance also enables the management of risks, issues, changes, and dependencies that may arise during the ADM process1.
Some of the benefits of governing the ADM process are2:
*Improved alignment of the architecture with the business strategy and objectives
*Enhanced stakeholder engagement and communication
*Increased reuse and integration of architecture assets and resources
*Reduced complexity and duplication of architecture efforts
*Increased agility and adaptability of the architecture to changing needs and requirements
*Improved compliance and auditability of the architecture outcomes and outputs
Which deliverable is first produced in Phase A, also updated in Phase E, and helps the architect to understand the baseline and target for the enterprise?
Comprehensive and Detailed Explanation
The question is about a deliverable that:
Is first created in Phase A: Architecture Vision.
Is updated in Phase E: Opportunities and Solutions.
Helps the architect understand both the baseline and the target for the enterprise.
Let's review each option:
A . Architecture Contracts
These are created in Phase G: Implementation Governance.
They formalize agreements between architecture and implementation teams, but are not produced in Phase A.
Incorrect.
B . Capability Assessment
In Phase A, the Capability Assessment is produced to assess the organization's current capability maturity and to identify strengths and weaknesses (baseline).
In Phase E, it is updated to reflect the required target capability and to inform planning of the work packages and Transition Architectures.
This deliverable helps architects understand both baseline and target capability for the enterprise.
Correct.
C . Consolidated Gaps, Solutions, and Dependencies Matrix
This is produced in Phase E to consolidate results from Gap Analysis across Phases B, C, and D.
It is not started in Phase A, so it does not meet the condition.
Incorrect.
D . Stakeholder Map
This is produced in Phase A as part of stakeholder management.
It is not updated in Phase E, and it does not directly address baseline vs. target capability.
Incorrect.
Correct Mapping
The deliverable that fits all three conditions is the Capability Assessment (B).

Which of the following statements about architecture partitioning is correct?
Based on the web search results, architecture partitioning is a technique that divides the Enterprise Architecture into smaller and manageable segments or groups, based on various classification criteria, such as subject matter, time, maturity, volatility, etc.12 Architecture partitioning is used to simplify the development and management of the Enterprise Architecture, by reducing complexity, improving governance, enhancing reusability, and increasing alignment and agility12. Therefore, the statement that partitions are used to simplify the management of the Enterprise Architecture is correct.
The other statements are incorrect because:
*Partitions are not equivalent to architecture levels. Architecture levels are different layers of abstraction that describe the Enterprise Architecture from different perspectives, such as strategic, segment, and capability3. Partitions are subsets of architectures that are defined within or across the levels, based on specific criteria1.
*Partitions do not necessarily reflect the organization's structure. The organization's structure is one possible criterion for partitioning the architecture, but it is not the only one. Other criteria, such as business function, product, service, geography, etc., can also be used to partition the architecture12.
*Partitions are not defined and assigned to agile Enterprise Architecture teams. Agile Enterprise Architecture is an approach that applies agile principles and practices to the architecture work, such as iterative development, frequent feedback, adaptive planning, and continuous delivery4. Partitions are not a specific feature of agile Enterprise Architecture, but a general technique that can be applied to any architecture method or framework, including TOGAF12.
Complete the sentence. The purpose of the Gap Analysis technique is to _____.
Comprehensive and Detailed Explanation
Gap Analysis is an ADM technique used in Phases B, C, and D of the TOGAF ADM (Business, Information Systems, and Technology Architectures).
Its main purpose is to validate the target architecture by comparing the Baseline Architecture with the Target Architecture and identifying:
Gaps (building blocks or capabilities present in the target but missing in the baseline).
Overlaps (building blocks duplicated across architectures).
Conflicts (inconsistencies between baseline and target).
The output of Gap Analysis provides:
A validated Target Architecture.
A set of identified gaps that must be addressed by future work packages in Phase E: Opportunities and Solutions.
Therefore, the purpose of Gap Analysis is best expressed as to validate the architecture (Answer D).
Why the other options are incorrect
A . Establish quality metrics for the architecture: This is part of performance management and governance, not Gap Analysis.
B . Identify non-functional requirements: Non-functional requirements are captured through requirements management and stakeholder analysis, not Gap Analysis.
C . Determine service levels: Service levels are typically defined in SLAs and operational models, not through Gap Analysis.
