7 - ADM Phases Flashcards
Preliminary Phase: Description
Understand business environment, ensure high-level management commitment, obtain agreement on scope, establish governance structure, custom TOGAF setup
Preliminary Phase: Objectives
Determine Arch Capability desired: Review org context, identify scope / framework methods, capability maturity target; establish the architecture capability
Preliminary Phase: Approach
Define enterprise, identify key drivers and elements, define requirements, principles and maturity. Framework to be used: BUSINESS CAPABILITY MANAGEMENT / PROJECT MANAGEMENT METHODS / OPERATION MANAGEMENT / SOLUTION DEVELOPMENT. Capability Maturity Models to asess ability of an enterprise
A: Architecture Vision: Description
Create an architecture vision validate the business context and create approved statement of Architecture Work
A: Architecture Vision: Objectives
Develop high-level vision of capabilities & business value delivered by proposed EA / optain approval for statement of Architecture work
A: Architecture Vision: Approach
Request for Architecture Work / Create Vision with Business Scenarios / Business Architecture and provides first cut base / target architecture
B: Business Architecture: Definition
Business Process and People, their relationships, principles
B: Business Architecture: Objectives
Develop Target Business Architecture, Architecture Roadmap based upon GAPs
B: Business Architecture: Approach
Develop Baseline Description, Business Modeling (use case models and BPM), Using Architecture Repository (e.g Common/ Industry Architectures) and standards
C. Information Systems Architectures: Definition
Document data & application architectures
C. Information Systems Architectures: Objectives
Develop target information systems (data & application) and baseline for request for architecture work, identify Architecture Roadmap
C. Information Systems Architectures: Approach
Key consideration: Data Management (define application components, standards), Data Migration, Data Governance and using repository
D: Technology Architecture: Definition
Documenting Technology Architecture: Hardware, software and communication tech
D: Technology Architecture: Objectives
Develop Tech Architecture / adress request for work
D: Technology Architecture: Approach
Consider what relevant tech architecture is in the repository: Technical Reference Model etc.
E: Opportunities & Solutions: Definition
Key Activities: Perform inital implementation planning, identify major implementation projects, make versus buy / C-Off the Shelf, priorities
E: Opportunities & Solutions: Approach
How to deliver architecture: Work packages, best fit roadmap, migration plan for Phase F
F: Migration Planning: Definition & Objectives & Approach
Cost benefit analysis for work packages, finalize detailed implementation; OBJECTIVES: Finalize Road map, ensure implementation, ensure business value
F: Migration Planning: Approach
G: Implementation Governance
Arch oversight, constraints, monitor. OBJECTIVES: Ensure conformance, perform governance. APPROACH: Actual development occurs in parallel within phase G - adopt phased development schedule
H: Change Management
Provide monitoring of change, ensure life cycle: Drivers for change: Strategic top down, bottom up and experiences
Change Mangement Process
Simplification change: can normally be handled via change management techniques
Incremental change: may be handled by cm tech. or require partial re-architecting
Re-architecting change: requires putting wole architecture through ADM again
