When should MMIS and /or E&E milestone reviews be conducted?

Alignment with the state's system development life cycle happens during the Project Initiation phase, specifically during Activity 1: Consult with CMS. The state should incorporate CMS milestone reviews into the state's project schedule. The flexibility is in scheduling, not whether milestone reviews are performed. Decisions made between the state and CMS are documented in the Project Partnership Understanding document and can be updated as needed throughout the life cycle.
