TOGAF Fases | Mind Map

Phase A. Architecture Vision high level description of the baseline and target A, high level view on target A.Goals:To secure formal approval to proceed. To articulate architecture vision.

Initiated by Request for A Work

A Vision document a tool for selling the benefits of theproposed capability to stakeholders. Describes how newcapability will address stakeholder concerns

Here first validated business principles, bgoals and strategic drivers

Buss principles are most prominent here

Statement of Architecture Work defines the scope and

approach that will be used to

complete an architecture development cycle

Business Scenarious recommended to helpidentify and understand requirements. Definethem and articulate the A Vision created in phaseA

Phase B. Business Architecture. To demonstrate how stakeholder concerns are addressed in the Buss A. Provides prerequisite knowledge for undertaking work in the other a domains. Not to defining the strategic business plan.

Select reference models,viewpoints,and tools

Develop Baseline BusinessArchitecture Description

If no 1/few architecture assets exists use Bottom Up approach

Develop Target Business ArchitectureDescription

Perform gap analysis

Define candidate roadmap components

Resolve impacts across the ArchitectureLandscape

Conduct formal stakeholder review

Finalizethe Business Architecture

Create Architecture Definition Document

Phase C. Information System Architecture. Most relevant model to use III Ref Model. Not Objective: definig data entities that are normalized to minimize update anomalies

Develop the Target Application Architecture thatenables the Business Architecture and theArchitecture Vision

Identify candidate Architecture Roadmap

Develop Data A and ApplicationA in either sequence

Requirements Management Responsible for managing the flow of requirements. It's Ongoing activity, that visited throughout project. Store r and manages their flow into relevant ADM phases

Phase H. Architecture Change Management Not includes: Business Scenarios. Ensuresthat A achieves its target

Simplification change. Example multiplesystems consolidated into 1. To reduceinvestments

Incremental change is driven by requirement toderive aditionsl value from the existinginvestment

Rearchitecting change to increase investment inorder to create new value to exploitation
