Which phase's key deliverables include a technical blueprint and sandbox migration?

The Explore Phase's key deliverables include both a technical blueprint and sandbox migration because this phase is centered around validating and refining the project requirements as well as determining how the system will be configured to meet those needs. During the Explore Phase, teams leverage workshops to gather detailed requirements, and they document these in the technical blueprint. This blueprint serves as a foundational design for the solution.

Additionally, sandbox migration is an important deliverable in this phase since it establishes a preliminary system that can be used for testing prototypes, validating configurations, and performing user training. This hands-on experience ensures that stakeholders can review and refine the solution based on actual usage scenarios before the system is built out in subsequent phases.

In summary, the Explore Phase emphasizes the importance of thorough planning, validation, and testing through deliverables like the technical blueprint and sandbox migration, setting the stage for successful implementation in later phases.
