The Architecture Development Method (ADM) is a key component of the TOGAF framework, which provides a comprehensive approach to enterprise architecture development. The ADM provides a structured approach for developing and managing enterprise architectures that align with business objectives and meet stakeholder needs. To maximize the benefits of the ADM process, it is important to understand how it can be adapted to meet the specific needs of an organization.
The TOGAF ADM Guidelines provide practical guidance for adapting the ADM process to deal with a range of different usage scenarios, such as incorporating iterative approaches, adapting for specific architectures, different process styles, and organizational structures. By following these guidelines, organizations can optimize their enterprise architecture development process and improve the alignment of their architectures with business goals.
Guidelines for Adapting the ADM Process:
- Applying Iteration to the ADM: This guideline explores the concept of iteration and its potential benefits when applied to the ADM process. It outlines various strategies for incorporating iterative approaches into the ADM, including incremental development and agile methodologies. The guideline also provides recommendations for selecting appropriate iteration approaches based on the needs of the organization.
- Applying the ADM across the Architecture Landscape : This guideline focuses on the different levels of architecture engagement within an enterprise and how the ADM can be adapted to support these different levels. It provides guidance on how to tailor the ADM process for specific types of architecture engagement, such as strategic planning or project delivery. The guideline also highlights the importance of aligning the ADM with the organization’s overall business strategy.
- Adapting the ADM for Specific Architectures: This guideline provides recommendations for adapting the ADM process to accommodate specialized architecture domains, such as security or data architecture. It outlines the unique considerations and challenges associated with these domains and provides guidance on how to integrate them into the ADM process effectively.
- Adapting the ADM for Different Process Styles: This guideline explores the various process styles that can be used in conjunction with the ADM process, such as lean or Six Sigma methodologies. It provides recommendations for integrating these process styles into the ADM and highlights the potential benefits of doing so.
- Adapting the ADM for Different Organizational Structures: This guideline addresses the challenges associated with adapting the ADM process to suit different organizational structures, such as those with decentralized decision-making or those with highly centralized governance models. It provides recommendations for tailoring the ADM process to fit these structures and suggests approaches for managing stakeholder engagement in these contexts.
Applying Iteration to the ADM
The concept of iteration is a critical component of the Architecture Development Method (ADM) within the TOGAF framework. There are three key ways in which iteration is used to support the ADM process.
The TOGAF ADM suggests a set of iteration cycles that can be used to effectively group related architectural activities to achieve a specific purpose.
The TOGAF ADM provides a structured framework for developing and implementing an enterprise architecture. It is divided into phases and iterations, with each iteration representing a logical grouping of related activities that are designed to achieve a specific purpose. The recommended iteration cycles for the TOGAF ADM are:
- Preliminary Phase: This phase is focused on establishing the business case for enterprise architecture development, identifying the stakeholders and their concerns, and defining the scope of the enterprise architecture effort.
- Architecture Vision Phase: This phase is focused on developing a high-level view of the enterprise architecture, including the business goals, strategic drivers, and key business requirements.
- Business Architecture Phase: This phase is focused on developing a detailed view of the organization’s business architecture, including the business processes, organization structure, and business capabilities.
- Information Systems Architecture Phase: This phase is focused on developing a detailed view of the organization’s information systems architecture, including the data architecture, application architecture, and technology architecture.
- Technology Architecture Phase: This phase is focused on developing a detailed view of the organization’s technology infrastructure, including the hardware, software, and network components.
- Opportunities and Solutions Phase: This phase is focused on identifying and evaluating potential solutions to address the business requirements and achieve the enterprise architecture goals.
- Migration Planning Phase: This phase focuses on developing a comprehensive plan for transitioning from the current architecture to the target architecture.
- Implementation Governance Phase: This phase is focused on establishing the governance framework for managing the implementation of the enterprise architecture.
- Architecture Change Management Phase: This phase is focused on managing the changes to the enterprise architecture over time, including monitoring the implementation of the architecture, and making changes as needed.
These iteration cycles can be customized and repeated as necessary to meet the specific needs of the organization and to achieve the desired outcomes.
- Architecture Development Iteration – The iteration is used to describe the process of developing a comprehensive Architecture Landscape through multiple ADM cycles, each of which is focused on individual initiatives within the scope of the Request for Architecture Work.
- Transition Planning Iteration – The iteration is used to describe the integrated process of developing an architecture, where the activities within different phases of the ADM interact to produce an integrated architecture. This type of iteration is often described in sequential terms to clearly define the activities and outputs.
- Architecture Governance iterations – The iteration supports the governance of change activity that is progressing towards a defined Target Architecture.
- Architecture Capability Iteration – The iteration is used to describe the process of managing change to the organization’s Architecture Capability, where continuous improvement is achieved through ongoing iteration and refinement of the ADM process. By incorporating these iterative concepts into the ADM process, organizations can enhance their architecture development capabilities and ensure that their architectures remain aligned with their evolving business needs.
This article provides a comprehensive guideline for organizations to apply iterative cycles to the TOGAF ADM in order to maximize the effectiveness of their enterprise architecture development efforts. The guideline would outline the key principles and best practices for using iterative cycles in the TOGAF ADM, including how to tailor the iteration cycles to the specific needs of the organization and how to integrate feedback from stakeholders throughout the development process. The ultimate goal of the guideline would be to help organizations achieve their enterprise architecture objectives more efficiently and effectively by leveraging the power of iterative development methodologies.
In summary, developing architectures at different levels within an organization requires a structured approach that takes into account the different stakeholder needs and the need for alignment with overall business goals and objectives. To achieve this, the TOGAF standard provides two strategies that can be employed:
- Architectures at different levels can be developed through iterations within a single cycle of the ADM process, allowing for the development of architectures at different levels within the same cycle.
- Architectures at different levels can be developed through a hierarchy of ADM processes, executed concurrently, with each level of architecture informing and guiding the development of the other levels.
Both strategies allow for the development of architectures at different levels of detail and abstraction, ensuring that all architectures are aligned with business goals and objectives and that they sit within a governance hierarchy.
