Which of the following tools will help facilitate the decision-making process when stakeholders do not agree on the value of an initiative?

Force-field analysis is a decision-making tool used to identify and analyze the forces for (driving forces) and against (restraining forces) a proposed change or initiative. When stakeholders disagree on the value, this tool facilitates a structured discussion by visualizing the pros and cons. It helps the group understand the sources of disagreement and work towards a consensus by identifying ways to strengthen driving forces and mitigate restraining ones, thereby clarifying the initiative's overall value proposition.

A. PEST analysis is used for external environmental scanning (Political, Economic, Social, Technological), not for resolving internal stakeholder disagreements on value.
C. Feasibility analysis determines if an initiative is viable (e.g., technically, financially). It answers "can we do it?" not "what is its value?"
D. Gap analysis identifies the difference between the current and future states. It defines the scope of work, but does not resolve disputes over an initiative's value.
