Which of the following is required to validate a project?

A problem statement defines the issue a project aims to address, but it does not, by itself, validate the project's strategic importance or alignment.

A signed project charter formally authorizes the project and outlines its initial scope, but project validation goes deeper to ensure strategic alignment beyond mere authorization.

Key project deliverables are the tangible outputs of a project, not the criteria for its initial validation or strategic justification.

Project validation fundamentally requires confirming that the project's goals, scope, and expected outcomes directly support and contribute to the organization's strategic objectives and overall mission. This ensures the project is valuable and justifiable from a business perspective.
