ADM Phase Objectives


The ADM (Architectural Development Method) is the core of the TOGAF framework. Each phase in the ADM has defined objectives and steps in the development of an enterprise architecture.


Capability Assessment


Before we start off with a detailed Architecture Definition, it is important to assess and understand the architecture capability of the organization. It is important to understand the baseline and target capability level of the enterprise.


BTR Assessment


The Business Transformation Readiness Assessment is carried out in Phase A. It is used for evaluating and quantifying the organization’s readiness to undergo change. To be successful in an architecture transformation, it is important that the organization is to accept a change.


Stakeholder Management


Any project has many implications to many people - hence there are many stakeholders, who can influence the project in either way. Stakeholder management is an important discipline for a successful architect. That is important to ensure the project has the required support and backing through its life.


Architecture Vision


The Architecture Vision is created in Phase A. It provides a high-level summary of the changes to the enterprise - that will follow the successful deployment of the Target Architecture. The purpose of the vision is to agree at the outset the desired outcome of the architecture.


Statement of Architecture Work


Based on the Request for Architecture Work (from Preliminary Phase), Phase A produces the Statement of Architecture Work. It can be considered as a contract between the architecting organization and the sponsor of the architecture project.


Request for Architecture Work


The intention of the sponsoring organization is formally translated into a request for architecture work - in the preliminary phase. The request for architecture work is sent from the sponsoring organization to the architecture organization to trigger the start of an architecture development cycle. This is formally produced with the assistance of the architecture organization as an output of the preliminary phase.


Data Priinciples


The data architecture is worked in the phase C. But, the principles of the data architecture are defined in the Preliminary phase and refined in the Architecture Vision phase. TOGAF recommends some fundamental data principles, which can be tailored and applied for the enterprise in question.


Business Principles


Business principles and business goals are fundamental to the organization, and are usually defined much before the architecture activity was even conceived. But, in the preliminary phase, we need to restate them in a form relevant to the enterprise architecture.


Architecture Principles


Principles are the guiding lights for any endeavor. So also for an enterprise architecture. Principles 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 mission. Essentially principles drive behavior of the enterprise.


What is AI?


AI is the buzzword of this decade. This blog gives a non-technical introduction to the basics of AI. What is AI, how it stared, where are we heading...


Architecture Scope


They say, "Work expands to fill the time available to do it". Similarly, architecture updates expand to scratch all that is available for change. It needs to be restricted. The Architecture Scoping process defines these restrictions.


ADM in Detail


ADM forms the core of the TOGAF framework. It helps derive organization specific enterprise architectures - by addressing the business requirements. It is a time tested method based on the contributions from many architecture practitioners.


What is TOGAF?


The TOGAF standard is a framework - a framework for Enterprise Architecture. It defines a standard approach that can assist you in working with an Enterprise Architecture. That includes acceptance, production, use, and maintenance of Enterprise Architectures.


Contents of TOGAF Framework


The TOGAF Standard helps us define the structure and content of an architecture capability in an enterprise. The different components of the standard define the different aspects of an enterprise architecture. The TOGAF standard is defined in five important parts. These five parts and the interaction between them defines a good enterprise architecture.


Organization Model


The Preliminary Phase involves tailoring the TOGAF framework for integration with the enterprise. But, that does not mean that we alter the entire spirit of TOGAF to match and fit the organization. If there is a lacking in the organization, we might need to alter the organization itself.


Tailor Architecture Framework


The magnanimity of an enterprise level architecture project can be scary - even for the most experienced architects. TOGAF can help us overcome this initial panic, by providing a guide at steps. It provides systematic "codified common sense"


Definitions of key terms in TOGAF


One of the key advantages of using a framework like TOGAF is the consistency of terms. The framework provides a clear definition of terms that prevents confusion over the meaning implied by the terms used by different stakeholders in the course of architecture development.


Introduction to the TOGAF ADM


The TOGAF standard is based on an iterative process model. It is supported by defined best practices along with a set of reusable architecture assets. This Architecture Development Method is the core of TOGAF


Enterprise Architecture


A good Enterprise Architecture is an important step leading maturity of enterprise. the open group advocates the need for a consistent architecture across the enterprise to enable information flow across the enterprise. Let us try to understand the concepts in detail.


Taxonomy of IIIRM


The IIIRM provides a taxonomy, which defines the terminology. It provides a coherent description of the components, along with conceptual structure of an integrated information infrastructure.
