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.

The TOGAF standard covers the development of four architecture domains: Business, Data, Technology and Application. These domains represent different aspects of an enterprise’s architecture and provide a consistent way of describing, analyzing, and designing them. Reference: The TOGAF® Standard | The Open Group Website, Section 2.2 Architecture Development Method (ADM).

According to the TOGAF standard, the deliverables that match the descriptions are as follows:

1 Architecture Principles: These are general rules and guidelines, intended to be enduring and seldom amended, that inform and support the way in which an organization sets about fulfilling its mission1. They reflect a level of consensus among the various elements of the enterprise, and form the basis for making future IT decisions1.

2 Architecture Contracts: These are the joint agreements between development partners and sponsors on the deliverables, quality, and fitness-for-purpose of an architecture2. They are used to ensure that the architecture is implemented and governed according to the agreed-upon specifications and standards2.

3 Request for Architecture Work: This is a document that is sent from the sponsoring organization to the architecture organization to trigger the start of an architecture development cycle3. It defines the scope, schedule, budget, deliverables, and stakeholders of the architecture project3.

4 Architecture Requirements Specification: This is a set of quantitative statements that outline what an implementation project must do in order to comply with the architecture4. It defines the requirements for each architecture domain, as well as the relationships and dependencies among them4.

According to the TOGAF Standard, 10th Edition, documents which are under development and have not undergone any formal review and approval process are called draft documents, while documents which have been reviewed and approved are called approved documents 1. Draft documents are typically marked with a version number of 0.x, indicating that they are incomplete or provisional. Approved documents are typically marked with a version number of 1.0 or higher, indicating that they have been finalized and authorized. The other options are not correct, as they are not the terms used by the TOGAF Standard to distinguish between documents under development and documents that have been reviewed and approved. The terms “finalized”, “concept”, “deliverable”, and “Version 0.1” and “Version 1.0” are not specific to the TOGAF Standard, and they may have different meanings or interpretations in different contexts. References: 1: TOGAF Standard, 10th Edition, Part II: Architecture Development Method, Chapter 7: Applying Iteration to the ADM, Section 7.2.3 Document Categorization.

An Enterprise Architecture Capability is the ability of the organization to perform effective and efficient architecture work, including the definition, governance, and management of its architectures2. The Preliminary Phase involves the following activities1:

•Reviewing the organizational context, scope, and drivers for conducting Enterprise Architecture

•Establishing the Architecture Capability desired by the organization, including the maturity level, roles, responsibilities, processes, and tools

•Defining and establishing the Organizational Model for Enterprise Architecture, which describes how the architecture function is organized and integrated within the enterprise

•Defining and establishing the Architecture Governance framework, which provides the mechanisms for ensuring the quality, consistency, and compliance of the architecture work

•Selecting and implementing the tools that support the Architecture Capability, such as repositories, modeling tools, and communication tools

•Defining the Architecture Principles that will guide and constrain the architecture work, based on the business principles, goals, and drivers of the organization

•Defining the Organization-Specific Architecture Framework, which is an adaptation of the generic TOGAF ADM to suit the specific requirements, standards, and practices of the organization

The Preliminary Phase is essential for preparing the organization for the successful development and implementation of its architectures, as well as for ensuring the alignment of the architecture work with the business strategy and objectives1.

1E: To identify delivery vehicles (projects programs portfolios) that will deliver the Target Architecture 2F: To confirm readiness and ability to undergo change 3E: To determine whether an incremental approach is required and if so identify Transition Architectures that will deliver continuous business value 4G: To perform appropriate governance functions while the solution is being implemented

According to the TOGAF Standard, Version 9.2, an architecture view is a representation of a system from the perspective of a related set of concerns1. It consists of one or more architecture models that demonstrate how the system addresses the stakeholder concerns1.

An architecture viewpoint is a specification of the conventions for constructing and using an architecture view to address specific stakeholder concerns1. It defines the perspective, scope, notation, and techniques for creating an architecture view of a system1.

Architects can present architecture views and viewpoints to stakeholders to extract hidden agendas, principles, and requirements that could impact the final Target Architecture, because23:

Architecture views and viewpoints help to communicate and visualize the architecture in a way that is meaningful and relevant to different stakeholders, addressing their specific interests and needs.

Architecture views and viewpoints help to elicit and validate the stakeholder concerns and requirements, ensuring that they are aligned with the business goals and objectives, and that they are consistent and feasible within the architecture context.

Architecture views and viewpoints help to identify and resolve any conflicts, gaps, or trade-offs among the stakeholder concerns and requirements, ensuring that they are balanced and prioritized in the architecture design and decision-making.

Architecture views and viewpoints help to demonstrate and verify the value and benefits of the architecture to the stakeholders, ensuring that they are satisfied and committed to the architecture outcome and governance.

Business scenarios are a technique recommended by the TOGAF ADM for use in developing an Architecture Vision document12. Business scenarios are a means of capturing the business requirements and drivers, the processes and actors involved, and the desired outcomes and measures of success34. Business scenarios help to create a common vision and understanding among the stakeholders, and to identify and validate the architecture requirements . Business scenarios also provide a basis for analyzing the impact and value of the proposed architecture. References:
