In a hybrid delivery approach, the product owner (who had been managing the project) was promoted and a new project lead joined. Which artifact should the project lead use to confirm the project's benefits have been identified?

The business case is the primary artifact that justifies the project's existence by documenting the identified business needs, project objectives, and the expected benefits. A new project lead would consult the business case to understand the rationale and value proposition of the project. The Statement of Work (SOW) defines the scope of work for a vendor or contractor, not the project's internal benefits. The product backlog lists prioritized features and requirements, but not the overarching business benefits. Solution architecture describes the technical design of the solution, not the project's benefits.
