The correct answer is C. RACI matrix . When stakeholders disagree about their level of involvement, the facilitator needs a tool that clarifies roles, responsibility, authority, consultation, and communication expectations . A RACI matrix directly addresses this issue because it defines who is Responsible , Accountable , Consulted , and Informed for each activity or decision. In VM and VE practice, a RACI matrix is specifically used to identify who is responsible for implementation, who is accountable for costs and outcomes, who needs to be consulted during VM/VE studies, and who needs to be kept informed.
This makes RACI especially useful when involvement levels become controversial. It gives the facilitator a neutral structure to move the group away from personal preference and toward agreed participation logic. It also helps prevent over-involvement, under-involvement, unclear decision authority, and unnecessary stakeholder conflict.
A work breakdown structure defines work packages, not stakeholder engagement levels. SWOT analysis examines strengths, weaknesses, opportunities, and threats, but does not assign participation roles. Paired comparison is used for prioritizing options or criteria, not resolving involvement disagreements.
