What & How Concepts
Building Blocks(WHAT)
Differentiators(HOW)
Process (HOW)
Function (WHAT)
▷ How can I do something ?
▷ Differentiators point of views
▷ Eg : How I Make Coffee ?
▷ Identify what you have ?
▷ Basic unit from which something is built up.
▷ What Building blocks you have ?
▷ Eg : What I Have to Make Coffee ?
Everything about architecture relates to these concepts

▷ Abstract framework for understanding significant
relationships among the entities of some environment,
and for the development of consistent standards or
specifications supporting that environment
▷ Collection of commonly uses Building blocks in enterprise
▷ More and More Architecture , you start build your own RM
▷ You can use any reference model and align it with
your enterprise like Data RM , Performance RM , etc.

3Architecture Development Method
▷ ADM Phases
▷ ADM Iterations
![Page 12: Togaf 9.1 Core Concepts](https://reader031.fdocuments.in/reader031/viewer/2022031809/5aac6e2e7f8b9a435e8b4ab1/html5/thumbnails/12.jpg)
Architecture Development Method ( ADM)
▷ Add and Consume B.B
▷ Can Apply Iterations ( ADM Guidelines)
▷ Can apply on different levels of details ( Segmentation)
▷ Repeatable process for developing Architectures
▷ Include Establish Architecture Framework , develop Architecture
content , Transitioning , govern realization of architectures
▷ Iterative Cycle of Continuous architecture definition
▷ Transform enterprise in response to business goals and
opportunities
ADM focus Points
![Page 13: Togaf 9.1 Core Concepts](https://reader031.fdocuments.in/reader031/viewer/2022031809/5aac6e2e7f8b9a435e8b4ab1/html5/thumbnails/13.jpg)
Architecture Partitioning
▷ Allows for direction setting at an executive level.
Strategic Architecture
Segment Architecture
▷ Allows for direction setting and the development of
effective architecture roadmaps at a program or
portfolio level.
Capability Architecture
▷ Development of effective architecture
roadmaps realizing capability increments.

ADM PhasesPreliminary Phase
▷ Establish Architecture Capability
▷ Define architecture principles
Phase A : Architecture Vision
▷ Create Vision for [iteration , partitioning ]
▷ Define scope , identify stakeholders , obtain approvals

ADM PhasesPhase E : Opportunities and solutions
▷ identify major implementation projects group them into work packages
▷ Solution Architect involved in this phase
Phase G : Implementation Governance
▷ Handover your projects to be implemented by
[ internal dev team , vendor , outsource]
▷ Compliance architecture to out business
[I Give you this / You deliver this / What is the gaps]
Phase F : Migration Planning
▷ Detailed implementation and migration plan by PMO
▷ Include [ cost – time – effort – resources – critical projects –
align other projects (strategic , segmented , capability)]
![Page 16: Togaf 9.1 Core Concepts](https://reader031.fdocuments.in/reader031/viewer/2022031809/5aac6e2e7f8b9a435e8b4ab1/html5/thumbnails/16.jpg)
ADM Iterations
▷ Architecture Capability Iteration
▷ Architecture Development Iteration
▷ Architecture Transition Iteration
▷ Architecture Governance Iteration
![Page 17: Togaf 9.1 Core Concepts](https://reader031.fdocuments.in/reader031/viewer/2022031809/5aac6e2e7f8b9a435e8b4ab1/html5/thumbnails/17.jpg)
ADM Iterations – Development Iteration
1. Define stakeholders view , viewpoints , concerns
2. Reference model if exist , Building blocks if exist
3. AS-IS architecture according to vision
4. TO-BE architecture
5. GAP analysis between AS-IS and TO-BE
Phase B –Phase C – Phase D
Above steps depends of Vision of iteration
Step may be not exist according to Vision

▷ Maturity Model Graph
▷ EA Scope Graph
▷ EA & SA & PMO

Levels of Maturity ( EA Seen from Business View)
▷ Each step between A-B ,
you will cycle in Maturity model
▷ Move from point A-B
▷ Most organizations in point A
▷ True value of EA in point B
Enterprise Planning
▷ Show true Value of EA
▷ Help to take decisions
▪ Business Planning
▪ Business Analytics
▪ BI
▪ EA
▷ We are not deliver building blocks
▷ Architecture work not seen by business people
▷ They need something help them to take decisions

5Architecture Model
▷ Views –Viewpoints –Model
▷ Build Your Reference Model
▷ Architecture Landscape
![Page 24: Togaf 9.1 Core Concepts](https://reader031.fdocuments.in/reader031/viewer/2022031809/5aac6e2e7f8b9a435e8b4ab1/html5/thumbnails/24.jpg)
Architecture Model
Consume B.B
Add B.B
Architecture Model
To Build
▷ The representation of a related set of concerns
( Issues , Risks , Assumptions , Constraints) of stakeholder
▷ A view is what is seen from a viewpoint.
▷ Anything that matter to stakeholders (How they see the world right)
▷ Outcome of ADM , Pull B.B to build Architecture Model
▷ Give view of you organization
▪ At different states
▪ Across different times
Views
Viewpoint
▷ definition of the perspective from which a view is taken.
![Page 25: Togaf 9.1 Core Concepts](https://reader031.fdocuments.in/reader031/viewer/2022031809/5aac6e2e7f8b9a435e8b4ab1/html5/thumbnails/25.jpg)
View – Viewpoint – Airport System
▷ One view from pilot viewpoint , addresses the pilot's concerns
▷ Another view from air controller viewpoint , addresses the controller’s concerns
Views
Viewpoint
▷ One viewpoint describe of how the pilot sees the system
▷ Another viewpoint describe of how the controller
sees the system
