The correct answers are A. Encourage participation by those affected by the change and D. Appoint an oversight committee . In the Implementation Phase, the approved VM proposal must be converted from an accepted recommendation into an actual organizational action. When the proposal requires organizational change, technical approval alone is not enough; successful implementation depends heavily on acceptance, ownership, coordination, and follow-through.

Encouraging participation by those affected by the change is essential because employees, managers, operators, and process owners who must live with the change often understand the practical barriers, workflow impacts, training needs, and resistance points. Their involvement improves buy-in and reduces implementation failure.

Appointing an oversight committee is also appropriate because organizational change normally crosses departments, responsibilities, and authority levels. Oversight provides governance, monitors progress, resolves conflicts, confirms accountability, and ensures the approved VM proposal remains aligned with the intended value improvement.

Option B is less suitable because an implementation plan should be clear and controlled, but not so rigid that it prevents adjustment during organizational transition. Option C is not required; a consultant may help in special cases, but it is not a primary VM implementation requirement.
