Objective: Conduct mock data conversions to test transfer of data.

Phase 4 GuidanceLegend - Customer, Provider, Shared
Activities
1. Define and test conversion scenarios (S)
2. Design build and unit test data conversion including extracting, transforming, and loading procedures (S)
3. Design, build, and unit test validation/reconciliation reports (S)
4. Test manual conversion and document results (P)
5. Run mock conversion and document results (P)
6. Clean up data issues uncovered during mock conversions (S)
7. Repeat subsequent mock conversions and update scripts as necessary, cleansing more data each time until program team is satisfied with data accuracy (S)

Inputs

Stakeholders
• Program Manager (C, P)
• Functional Lead (C, P)
• Functional SME (C)
• Technical Lead/Solution Architect (C, P)
• Development Team (C, P)
• Network SME (C, P)
• Data Conversion Lead (C, P)
