ADM Objectives

A. Architecture Vision

Preliminary

Definition of framework, tools, principles

Set scope, contraints, expectations

B,C,D. Architectures

Develop architecture, develop Baseline and Target architecture, analyze gaps

E. Opportunities and Solutions

Inintial implementation planning and identification implemnt. vehicles for building blocks, defining major projects, group then into Transition architectures

F. Migration Planning

G. Governance Architecture

Analyze cost benefits/risks. Develop Migration Plan

Oversight of implementation for conforming to the architecture, Prepare and issue Architecture Contracts

H. Ghange Management

Continuous monitoring for ensuring that architecture responds to the needs of architecture and maximizes the value of business

Preliminary

View of Architecture Repository that shows transtion from generic to specific

Parts

Enterprise continuum

Architecture continuum

Solution continuum

Classifies policies, standards, strategic initiatives, organizational
structures, and enterprise-level capabilities

Describe and understand the implementation of the assets defined in the
Architecture Continuum

Define the generic rules, representations, and relationships in an
architecture, including traceability and derivation relationships

View, Viewpoint, Stakeholder

Stakeholders are people who have key roles in, or concerns about, the system

Concerns are key interests that are crucially important to stakeholders, and
determine the acceptability of the system

A view is a representation of a system from the perspective of a related set of
concerns.

A viewpoint defines the perspective from which a view is taken.
