- TOGAF is an architecture framework – The Open Group Architecture Framework. TOGAF provides the methods and tools for assisting in the acceptance, production, use, and maintenance of an enterprise architecture.
- It is based on an iterative process model supported by best practices and a re-usable set of existing architecture assets.
TOGAF ADM for EA Development
The ADM is central to TOGAF which describes a method for developing and managing the lifecycle of enterprise architecture and forms the core of TOGAF. It integrates elements of TOGAF described in this document as well as other available architectural assets, to meet the business and IT needs of an organization.
The TOGAF Architecture Development Method (ADM) provides a tested and repeatable process for developing architectures. Each phase of ADM below contains iterative (Continuous) sequence of steps to develop an enterprise-wide Architecture and the possible iterations:
Getting the organization committed and involved
- Preliminary Phase
- Phase A: Architecture Vision
Getting the Architecture right
- Phase B: Business Architecture
- Phase C: Information Systems Architectures
- Phase D: Technology Architecture
Making the Architecture work
- Phase E: Opportunities & Solutions
- Phase F: Migration Planning
- Phase G: Implementation Governance
Keeping the Process running
- Phase H: Architecture Change Management
- Requirement Phase: Requirements Management
Development Phases of Architecture Development Method
The TOGAF Architecture Development Method (ADM) provides a tested and repeatable process for developing architectures. The ADM includes establishing an architecture framework, developing architecture content, transitioning, and governing the realization of architecture.
All of these activities are carried out within an iterative cycle of continuous architecture definition and realization that allows organizations to transform their enterprises in a controlled manner in response to business goals and opportunities.
Phases within the ADM are as follows:
- The Preliminary Phase describes the preparation and initiation activities required to prepare to meet the business directive for new enterprise architecture, including the definition of an Organization-Specific Architecture framework and the definition of principles.
- Phase A: Architecture Vision describes the initial phase of an architecture development cycle. It includes information about defining the scope, identifying the stakeholders, creating the Architecture Vision, and obtaining approvals.
- Phase B: Business Architecture describes the development of a Business Architecture to support an agreed Architecture Vision.
- Phase C: Information Systems Architectures describes the development of Information Systems Architectures for an architecture project, including the development of Data and Application Architectures.
- Phase D: Technology Architecture describes the development of the Technology Architecture for an architecture project.
- Phase E: Opportunities & Solutions conducts initial implementation planning and the identification of delivery vehicles for the architecture defined in the previous phases.
- Phase F: Migration Planning addresses the formulation of a set of detailed sequences of transition architectures with a supporting Implementation and Migration Plan.
- Phase G: Implementation Governance provides architectural oversight of the implementation.
- Phase H: Architecture Change Management establishes procedures for managing change to the new architecture.
- Requirements Management examines the process of managing architecture requirements throughout the ADM.
Zoom into a TOGAF ADM Development Phase B
To understand how we can adapt ADM for EA development, let’s pick ADM Phase B as an example. We can all the steps (9 steps) involve for conducting the work in this phase as shown in the Figure below:
How to Conduct Development Phase of EA for TOGAF ADM?
- To start Phase B of Business Architecture, we first look at the objectives of this development phase.
- By following each of the nine steps (as shown in the Cheatsheet below), we need to references the input documentation or work which have been done in the previous development phases (the Preliminary and Phase A).
- Create a new deliverable, or sometimes you need to refine the previous documentation iteratively based on the steps which will fulfil the objectives of the phase.
Jump-Start TOGAF ADM Projects with Visual Paradigm
Enterprise Architecture is essential to every business, yet it’s not easy to master. Have you ever thought that you would be able to learn Enterprise Architecture solely by yourself? Visual Paradigm is here to help. Equipped with an intuitive TOGAF ADM process navigator, to develop Enterprise Architecture with Visual Paradigm is just like having a tutor sitting next to you, guiding you through the instructions, taking you through the ADM examples. All you need to do is to follow the on-screen instructions, fill-in some forms, draw some ArchiMate diagrams (3.0), and that’s it, the deliverables will be there for retrieval.
Visual Paradigm makes you an enterprise architect in no time at all – and with no training, as the actionable guide through process comes along with instructions, tips, samples and case study. Read through this tutorial, relax and see how the best TOGAF software can help you perform TOGAF activities and produce TOGAF deliverables with ease.
What does Visual Paradigm Offer?
TOGAF ADM is the process of developing an enterprise architecture, while Visual Paradigm features a process navigator that guides you through the execution and completion of TOGAF ADM. Broadly speaking, Visual Paradigm features/facilitates the following:
- An ADM process navigator that guides you through the development of enterprise architecture with TOGAF ADM, activity by activity, step by step
- Guide you through the creation of deliverables and artifacts, with clear instructions
- Generate deliverables upon the completion of an ADM phase
- Automatic archiving of deliverables in an Architecture Repository
- Helps you understand TOGAF by providing you with samples
- Provides the tools and diagrams you need in analysis and documentation, which includes ArchiMate 3 diagram tool and viewpoints (The Open Group certified), Implementation Plan Diagram, Migration Roadmap, Maturity Analysis, PERT Chart, RACI Chart, Implementation Factor Assessment & Deduction Matrix, Consolidated Gaps, Solutions, & Dependencies Matrix, etc.
You need a project to work on. To avoid messing up your production data, create a new project in Visual Paradigm first. You can create a new project by selecting Project > New from the application toolbar.
Opening the TOGAF ADM process navigator
You can access the ADM process navigator anytime throughout the ADM cycle by selecting ITSM > TOGAF ADM from the application toolbar.
You should see the screen below. You can double click on a phase to view its activities.
