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
