TOGAF 9.1 Released – What does it mean to you?

If you are planning to take up TOGAF certification examination, you would definitely want to know how the release of TOGAF 9.1 impacts you. You would want to which version you need to study.

Here is the simple guideline. If you are planning to appear for the exam…

  1. …before June 2012 the you should study TOGAF 9
  2. …between June 2012 and May 2013 then you can study either TOGAF 9 of 9.1
  3. …after June 2013 it is only TOGAF 9.1

In a nutshell, if you have already done most of the studying using TOGAF 9.0 then you have slightly more than a year to clear the exam. However, if you have yet to begin the study you better start with 9.1.

What are the main differences between TOGAF 9 and 9.1?

The Open Group has published a presentation in the form of a PDF which provides an overview of the differences – here is the link.

If you would prefer to have a look at the difference as a two pager then I recommend that you go through this post of Mike Walker.

However, I think the biggest difference between the two is how the objectives of each of the ADM phase are written. The latest version seems to be significant improvement. This is also the most important change for those of you who want to appear for the foundation level exam.

You may also need to go through Phase E and F more carefully as they have been reworked.

Comparison of ADM Objectives – TOGAF 9 vs. TOGAF 9.1

Phase Objective as per TOGAF 9 Objective as per TOGAF 9.1
Preliminary
  • To review the organizational context for conducting enterprise architecture
  • To identify the sponsor stakeholder(s) and other major stakeholders impacted by the business directive to create an enterprise architecture and determine their requirements and priorities from the enterprise, their relationships with the enterprise, and required working behaviors with each other
  • To ensure that everyone who will be involved in, or benefit from, this approach is committed to the success of the architectural process
  • To enable the architecture sponsor to create requirements for work across the affected business areas
  • To identify and scope the elements of the enterprise organizations affected by the business directive and define the constraints and assumptions (particularly in a federated architecture environment)
  • To define the ‘‘architecture footprint’’ for the organization — the people responsible for performing architecture work, where they are located, and their responsibilities
  • To define the framework and detailed methodologies that are going to be used to develop enterprise architectures in the organization concerned (typically, an adaptation of the generic ADM)
  • To confirm a governance and support framework that will provide business process and resources for architecture governance through the ADM cycle; these will confirm the fitness-for-purpose of the Target Architecture and measure its ongoing effectiveness (normally includes a pilot project)
  • To select and implement supporting tools and other infrastructure to support the architecture activity
  • To define the architecture principles that will form part of the constraints on any architecture work
  1. Determine the Architecture Capability desired by the organization:
    • Review the organizational context for conducting enterprise architecture
    • Identify and scope the elements of the enterprise organizations affected by the Architecture Capability
    • Identify the established frameworks, methods, and processes that intersect with the Architecture Capability
    • Establish Capability Maturity target
  2. Establish the Architecture Capability:
    • Define and establish the Organizational Model for Enterprise Architecture
    • Define and establish the detailed process and resources for architecture governance
    • Select and implement tools that support the Architecture Capability
    • Define the Architecture Principles
Phase A
  • To ensure that this evolution of the architecture development cycle has proper recognition and endorsement from the corporate management of the enterprise, and the support and commitment of the necessary line management
  • To define and organize an architecture development cycle within the overall context of the architecture framework, as established in the Preliminary phase
  • To validate the business principles, business goals, and strategic business drivers of the organization and the enterprise architecture Key Performance Indicators (KPIs)
  • To define the scope of, and to identify and prioritize the components of, the Baseline Architecture effort
  • To define the relevant stakeholders, and their concerns and objectives
  • To define the key business requirements to be addressed in this architecture effort, and the constraints that must be dealt with
  • To articulate an Architecture Vision and formalize the value proposition that demonstrates a response to those requirements and constraints
  • To create a comprehensive plan that addresses scheduling, resourcing, financing, communication, risks, constraints, assumptions, and dependencies, in line with the project management frameworks adopted by the enterprise (such as PRINCE2 or PMBOK)
  • To secure formal approval to proceed
  • To understand the impact on, and of, other enterprise architecture development cycles ongoing in parallel
  1. Develop a high-level aspirational vision of the capabilities and business value to be delivered as a result of the proposed enterprise architecture
  2. Obtain approval for a Statement of Architecture Work that defines a program of works to develop and deploy the architecture outlined in the Architecture Vision

 

Phase B
  • To describe the Baseline Business Architecture
  • To develop a Target Business Architecture, describing the product and/or service strategy, and the organizational, functional, process, information, and geographic aspects of the business environment, based on the business principles, business goals, and strategic drivers
  • To analyze the gaps between the Baseline and Target Business Architectures
  • To select and develop the relevant architecture viewpoints that will enable the architect to demonstrate how the stakeholder concerns are addressed in the Business Architecture
  • To select the relevant tools and techniques to be used in association with the selected viewpoints
  1. Develop the Target Business Architecture that describes how the enterprise needs to operate to achieve the business goals, and respond to the strategic drivers set out in the Architecture Vision, in a way that addresses the Request for Architecture Work and stakeholder concerns
  2. Identify candidate Architecture Roadmap components based upon gaps between the Baseline and Target Business Architectures

 

Phase C The objective of Phase C is to develop Target Architectures covering either or both (depending on project scope) of the data and application systems domains.Information Systems Architecture focuses on identifying and defining the applications and data considerations that support an enterprise’s Business Architecture; for example, by defining views that relate to information, knowledge, application services, etc.
  1. Develop the Target Information Systems (Data and Application) Architecture, describing how the enterprise’s Information Systems Architecture will enable the Business Architecture and the Architecture Vision, in a way that addresses the Request for Architecture Work and stakeholder concerns
  2. Identify candidate Architecture Roadmap components based upon gaps between the Baseline and Target Information Systems (Data and Application) Architectures

 

Phase D The Technology Architecture phase seeks to map application components defined in the Application Architecture phase into a set of technology components, which represent software and hardware components, available from the market or configured within the organization into technology platforms.As Technology Architecture defines the physical realization of an architectural solution, it has strong links to implementation and migration planning.Technology Architecture will define baseline (i.e., current) and target views of the technology portfolio, detailing the roadmap towards the Target Architecture, and to identify key work packages in the roadmap. Technology Architecture completes the set of architectural information and therefore supports cost assessment for particular migration scenarios. 
  1. Develop the Target Technology Architecture that enables the logical and physical application and data components and the Architecture Vision, addressing the Request for Architecture Work and stakeholder concerns
  2. Identify candidate Architecture Roadmap components based upon gaps between the Baseline and Target Technology Architectures

 

Phase E
  • To review the target business objectives and capabilities, consolidate the gaps from Phases B to D, and then organize groups of building blocks to address these capabilities
  • To review and confirm the enterprise’s current parameters for and ability to absorb change
  • To derive a series of Transition Architectures that deliver continuous business value (e.g., capability increments) through the exploitation of opportunities to realize the building blocks
  • To generate and gain consensus on an outline Implementation and Migration Strategy
  1. Generate the initial complete version of the Architecture Roadmap, based upon the gap analysis and candidate Architecture Roadmap components from Phases B, C, and D
  2. Deter mine whether an incremental approach is required, and if so identify Transition Architectures that will deliver continuous business value

 

Phase F
  • To ensure that the Implementation and Migration Plan is coordinated with the various management frameworks in use within the enterprise
  • To prioritize all work packages, projects, and building blocks by assigning business value to each and conducting a cost/business analysis
  • To finalize the Architecture Vision and Architecture Definition Documents, in line with the agreed implementation approach
  • To confirm the Transition Architectures defined in Phase E with relevant stakeholders
  • To create, evolve, and monitor the detailed Implementation and Migration Plan providing necessary resources to enable the realization of the Transition Architectures, as defined in Phase E
  1. Finalize the Architecture Roadmap and the supporting Implementation and Migration Plan
  2. Ensure that the Implementation and Migration Plan is coordinated with the enterprise’s approach to managing and implementing change in the enterprise’s overall change portfolio
  3. Ensure that the business value and cost of work packages and Transition Architectures is understood by key stakeholders

 

Phase G
  • To formulate recommendations for each implementation project
  • To govern and manage an Architecture Contract covering the overall implementation and deployment process
  • To perform appropriate governance functions while the solution is being implemented and deployed
  • To ensure conformance with the defined architecture by implementation projects and other projects
  • To ensure that the program of solutions is deployed successfully, as a planned program of work
  • To ensure conformance of the deployed solution with the Target Architecture
  • To mobilize supporting operations that will underpin the future working lifetime of the deployed solution
  1. Ensure conformance with the Target Architecture by implementation projects
  2. Perform appropriate Architecture Governance functions for the solution and any implementation-driven architecture Change Requests

 

Phase H

TOGAF

What is TOGAF – without jargon

Yes, TOGAF is an EA (Enterprise Architecture) framework – but what is that suppose to mean?

Imagine that you have to oversee the IT integration of 2 companies which has merged and they have different ERP, CRM, billing system and the customer facing process are different. The merged entity needs to rationalize the product offering and needs to project a uniform and integrated face to the customer. Obviously, this is going to be a big challenge – technological, people, process and change-management. How would you go about this complex transition? You can do a ground up thinking and make a plan or you can take the help on an EA framework like TOGAF and tailor it to your specific needs.

However, the important point that needs to be kept in mind is that TOGAF is NOT a methodology for managing software development. It will help you to identify what software to build – what need the software should satisfy – if you are planning to outsource the work, what should go into an RFP – even how to monitor the development and implementation.

ADM = Architecture Development Methodology

If you look around a little you will realize that the core element of TOGAF is ADM. Important point to remember is the “A” in ADM is ARCHITECTURE and not application.

[BTW: TOGAF = The Open Group Architecture Framework and the current version is 9]

You will also come across this diagram either in the Wikipedia page on TOGAF or on the Introduction to ADM page on the TOGAF site. I won’t blame you if you find the content in these pages to be too confusing. However, the annotated diagram on the left should be able to give you an overview.

Though the diagram has 10 circles, ADM is essentially a 4 step process.

  1. Tailor TOGAF to suit your need: this is a onetime activity to be done before you start adopting TOGAF for your organization
  2. Define scope of work and prepare plan for rollout: this activity is made of six distinct steps – we will get into the details in a later post
  3. Oversee development and implementation: how the actual development and implementation is done is not within the scope of TOGAF
  4. Manage post-implementation change: Any major change will trigger off another cycle of ADM

You may have multiple ADM cycles simultaneously running for different projects running within your organization. These projects need not be in sync.

Requirement Management = Central knowledge repository

The circle at the centre represents a knowledge repository. TOGAF was specific recommendations on how to organize the repository. We will see more about this in a later post.

I will also not get into the detail of what Enterprise Continuum is. If you had tried skimming through the TOGAF material, you surely would have encountered this term. It is a way of classifying item in the knowledge repository. On one dimension is to separate architecture and solution. On this other dimension is about moving from more generic to more specific (foundation, common system, industry, organization specific). Again, this requires more detailed discussion and we will do it in a later post.

Architecture as defined in TOGAF

The architecture is used in TOGAF in ways you would not normally use. You need some time to get used to it. The TOGAF study guide explicitly states that…

…”architecture” has two meanings depending upon the context:

  1. A formal description of a system, or a detailed plan of the system at a component level to guide its implementation
  2. The structure of components, their inter-relationships, and the principles and guidelines governing their design and evolution over time

At this stage I will not analyze this definition but draw your attention to 2 phrases – “detailed plan … to guide its implementation” and “evolution over time”. Do you find this different or confusing? You better get used to it.

If you come across the term Architecture Work, it means the work that needs to be done to move from baseline (current) architecture to target (desired) architecture. In simple term it means scope of work.

In the next post I will elaborate the 6 steps for defining scope of work and preparation of plan for rollout.
