What are the phases of TOGAF?
But in general, the 10 phases are sensible, running from creating the Target Model (Phase A), through Business, IS, Data, Technology architectures, into implementation details, migration, governance and change management.
What is the first phase of TOGAF?
This chapter describes the initial phase of the Architecture Development Method (ADM). It includes information about defining the scope, identifying the stakeholders, creating the Architecture Vision, and obtaining approvals.
What is the preliminary phase?
The Preliminary Phase defines the architecture principles that will form part of the constraints on any architecture work undertaken in the enterprise. The body responsible for governance will also normally be responsible for approving the architecture principles, and for resolving architecture issues.
How many phases are in ADM TOGAF?
ten Phases
The Architecture Development Method (ADM) has ten Phases, as identified here. The approach and complete description of each Phase are provided in the TOGAF documentation available on The Open Group website, to identify the objectives, inputs, steps and outputs of each phase.
What are TOGAF principles?
A TOGAF principle always has a: Name – Clear, precise, and easy to remember. Statement – Generally one sentence in length. Clearly tells you what the principle is. Rationale – Explanation of why the principle is important and how it will benefit the business.
What is ADM cycle?
The Architecture Development Cycle The phases are iterative, both within each phase and among phases. However, the ADM covers the complete architecture life-cycle. Note that output is generated throughout the process, and that the output in an early phase may be modified in a later phase.
What is ADM in TOGAF?
The Architecture Development Method (ADM) is applied to develop an enterprise architecture which will meet the business and information technology needs of an organization. It describes a method for developing and managing the lifecycle of an enterprise architecture, and forms the core of TOGAF.
What kind of architecture does TOGAF deal with?
TOGAF is an architectural framework – The Open Group Architectural Framework. It enables you to design, evaluate, and build the right architecture for your organization.
What is the importance of the preliminary phase?
The main objectives of the Preliminary Phase are to determine and establish the Architecture Capability desired by the organization. A key part of this is to define what needs to be done, and how it will be carried out.
What is the purpose of the preliminary phase?
The key objective of the Preliminary Phase is to establish the Architecture Capability for the enterprise. In practical terms this activity will require the establishment of a number of architecture partitions, providing defined boundaries, governance, and ownership.
How does ADM align?
The ADM is iterative over the whole process, between phases and within phases; for each iteration of the ADM, a fresh decision must be taken on: The breadth of coverage of the enterprise to be defined. The level of detail to be defined. Assets created in previous iterations of the ADM cycle within the enterprise.
What is the preliminary phase of the TOGAF standard?
The TOGAF ADM is a generic method, intended to be used by a wide variety of different enterprises, and in conjunction with a wide variety of other architecture frameworks, if required. The Preliminary Phase therefore involves doing any necessary work to initiate and adapt the ADM to define an organization-specific framework.
What is business architecture in TOGAF Phase B?
The Business Architecture will define the service contract at the business/functional level, which will be expanded on in the Application and Technology Architecture phases. The granularity of business services should be determined according to the business drivers, goals, objectives, and measures for this area of the business.
What are the phases of the TOGAF migration plan?
Gaps, or limitations, identified in the enterprise’s capability to execute on change will inform the architect on the description of the Target Architecture and on the Implementation and Migration Plan (see Part IV, 32.2.14 Implementation and Migration Plan) created in Phase E and Phase F.
How does TOGAF help organize the development process?
TOGAF helps organize the development process through a systematic approach aimed at reducing errors, maintaining timelines, staying on budget and aligning IT with business units to produce quality results.
