Image Map Phase 0: Assessment Phase 1: Readiness Phase 2: Selection Phase 3: Engagement Phase 4: Migration Phase 5: Operations
Objective: Perform knowledge transfer of as-is environment and finalize the Initial Target State Systems Environment that capture all required interfaces, application, security/privacy, and data layers.

Phase 3 GuidanceLegend - Customer, Provider, Shared
Activities
1. Perform knowledge transfer to provider to gain an understanding of the customer’s As-is Systems Environment including which interfaces to legacy systems will be required (C)
2. Review Initial Target State Systems Environment and compare against the provider’s standard solution to determine where gaps exist (S)
3. Develop solutions for technical gaps where enhancements are required to systems and infrastructure and where new interfaces will be required (P)
4. Assess gap solutions of technical environment based on cost and timeline implications and document impacts to release strategy (S)
5. Finalize Target State Systems Environment, through technical reviews if necessary, to define the scope of the migration and at each release, if applicable (S)
6. Report updates in governance meetings and Status Reports/Dashboards (S)
