Architecture Roadmaps Approach

Motivation

EA Roadmaps process

Key Stages of the EA roadmap process -   

• Discovery
• Collect all the current documentations from various sources
• Baseline the current state
• Document the current state of the architecture (Business, Applications, Tech, Mappings between various concepts using the Fan-Out method)
• Architecture Assessment - 
• Understand the reasons (Motivation) for change. 
• Conduct architecture assessment of the current state based on the business goals/objectives (End) and drivers(Influencers) using various proven tools (Reference Architectures, Heatmaps, Applications Portfolio Rationalisation Methods )
• Model the target state of the architecture (Reference architectures for Business, Applications, Tech layer, Mappings between various concepts using the top-down method)
• These models need to be socialised with various stakeholders and approved formally to initiate the change programs to identify target solutions.
• Transition Planning
• Breakdown the changes into multiple blocks and work with the management team to order them based on various priorities
• Build artefacts to govern the implementation phase if required
