Lesson 172 - TOGAF in 10 Minutes

Summary

In this episode of 'Software Architecture Monday,' Mark Richards offers a concise overview of TOGAF, The Open Group Architecture Framework. He emphasizes the Architecture Development Method (ADM) as TOGAF's core, which is adaptable to initiatives of varying scales. Richards outlines the framework's phases, from preliminary setup to architecture change management, highlighting how each phase addresses transformation, governance, and planning to realize an architecture vision. The video provides a clear introduction to TOGAF's structured approach to enterprise architecture.

Takeaways

• 📚 Mark Richards introduces TOGAF (The Open Group Architecture Framework) as a framework for enterprise architecture, contrasting it with the Zachman Framework discussed in a previous lesson.
• 🔍 TOGAF is described as an initiative-based process focused on facilitating change based on a new architecture vision, rather than a descriptive framework like Zachman.
• 🚀 The core of TOGAF is the Architecture Development Method (ADM), which acts as the 'engine' of the framework, driving the process of creating business solutions.
• 🛠️ The ADM consists of a set of phases, each dealing with transformation or governance aspects necessary for change based on a new architecture vision.
• 🔧 The preliminary phase of TOGAF involves preparation, initiation, and customization of the TOGAF process to fit the scale of the initiative, whether small or large.
• 🌟 Phase A of the ADM focuses on creating an architecture vision, defining the scope of changes, identifying stakeholders, and gaining their buy-in.
• 🏢 Phase B addresses the business architecture, considering workflow changes, organizational changes, and strategies to support the architecture vision.
• 💾 Phase C is about the information systems architecture, detailing the logical and physical data models necessary for the architecture vision, such as database transformations.
• 💻 Phase D covers the technology architecture, specifying hardware, software, platforms, and infrastructure needed to support the architecture vision.
• 🗺️ Phase E is about opportunities and solutions, creating a roadmap that outlines iterations and corresponding projects to achieve the architecture vision.
• ⏱️ Phase F involves migration planning, where the roadmap is refined with considerations for dependencies, priorities, staffing, cost, effort, and risk.
• 🛡️ Phase G is implementation governance, focusing on acceptance criteria, tracking issues, and leveraging fitness functions to ensure alignment with the architecture.
• 🔄 Phase H, the architecture change management, is about governance and measurement during implementation to ensure alignment with the vision and risk management.
• 📈 TOGAF also includes the Architecture Content Framework for creating and reusing artifacts and building blocks, and the Enterprise Continuum with reference models for feedback and accuracy.

Q & A

What is the main focus of the video script?

The main focus of the video script is an introduction to TOGAF, The Open Group Architecture Framework, including its core components and the Architecture Development Method (ADM).

What is TOGAF and why is it important?

TOGAF is a framework for enterprise architecture that provides a methodology and a set of supporting tools for developing an organization's architecture. It's important because it helps organizations align their business goals with their IT infrastructure and systems.

What is the ADM in the context of TOGAF?

The ADM, or Architecture Development Method, is the core engine of TOGAF. It's a process that produces business solutions by creating and reusing artifacts and building blocks, which are part of an architecture content framework.

How does TOGAF handle the relationship between business drivers and goals?

TOGAF handles the relationship between business drivers and goals through the Architecture Development Method, which starts with business needs and initiatives, and translates them into architecture visions and business solutions.

What are the phases of the TOGAF Architecture Development Method?

The phases of the TOGAF Architecture Development Method include Preliminary, Phase A (Architecture Vision), Phase B (Business Architecture), Phase C (Information Systems Architecture), Phase D (Technology Architecture), Phase E (Opportunities and Solutions), Phase F (Migration Planning), Phase G (Implementation Governance), and Phase H (Architecture Change Management).

Why does the presenter like TOGAF's ability to be customized?

The presenter likes TOGAF's customization ability because it allows the framework to be tailored to initiatives of varying sizes, from small projects to large enterprise-wide initiatives, making it flexible and adaptable.

What is the purpose of Phase A in the TOGAF ADM?

Phase A, the Architecture Vision phase, is where the scope of the necessary changes is defined, key stakeholders are identified, and an architecture vision is created to gain their buy-in and agreement.

How does TOGAF separate business, data, and technology?

TOGAF separates business, data, and technology through distinct phases: Phase B for business architecture, Phase C for information systems architecture (data), and Phase D for technology architecture.

What is the role of Phase E in the TOGAF ADM?

Phase E, Opportunities and Solutions, is where a roadmap is created, showing iterations and corresponding projects to achieve the architecture vision, and each iteration represents an opportunity to deliver business value.

How does TOGAF ensure alignment between implementation and architecture?

TOGAF ensures alignment through Phase G, Implementation Governance, where acceptance criteria are defined, outstanding issues are tracked, and fitness functions are leveraged to maintain alignment with the architecture vision.

What is the purpose of the Architecture Change Management phase in TOGAF?

The Architecture Change Management phase, Phase H, is focused on governance and measurement during implementation to ensure alignment with the architecture vision and to manage and mitigate risks throughout each iteration.
