The correct answers are B and D . A RACI matrix is most appropriate when the VM facilitator needs to clarify involvement, responsibility, accountability, consultation, and communication among participants or stakeholders. In the SAVE International Value Methodology Core Competencies, the RACI matrix is listed under the Information Phase as a method used to transform information, while process flowcharts are listed separately as a different technique. This distinction is important because a RACI matrix does not map process sequence; it clarifies roles and involvement.

A RACI chart defines who is Responsible, Accountable, Consulted, and Informed for project tasks, and it is used to reduce confusion, improve communication pathways, and establish clear ownership. ( Atlassian ) Therefore, it directly addresses communication gaps and misunderstood concepts related to who should act, decide, advise, or be kept informed.

Option A is incorrect because process-flow issues are better handled with a process flowchart. Option C is incorrect because validated assumptions do not require role clarification; they are already confirmed information.
