The correct answers are B. Maintenance, C. Production, and E. Engineering . The question is focused on how adding a new product will affect the current manufacturing process , so input must come from the functions that directly understand equipment capability, production workflow, process design, downtime risk, maintainability, tooling, tolerances, and operational constraints. SAVE’s Value Methodology Standard specifically states that VM can be applied to manufacturing processes , and that the Value Study Team should be a multidisciplinary group of experienced professionals and project stakeholders selected based on their expertise and experience with the project.
Production is essential because it understands line capacity, sequencing, labor flow, bottlenecks, cycle time, quality impact, and daily operating constraints. Maintenance is essential because a new product may require equipment changes, additional preventive maintenance, setup changes, spare parts, downtime planning, or reliability analysis. Engineering is essential because it understands product design, process capability, manufacturing methods, fixtures, tooling, specifications, and technical feasibility.
Marketing may provide market demand or customer preference input, but that is not the best answer when the question narrows the issue to the existing manufacturing process. Human resources may support staffing or training later, but it is not one of the three primary technical process stakeholders.
