Which statement is true about cost and schedule when requirements are stable and well managed?

• A. Program cost and schedule are more predictable.
• B. Unstable requirements have no impact on cost and schedule.
• C. Procurement funding is unrelated to purchasing goods.
• D. Management emphasis on cost guarantees on-time delivery.

Answer: (A)

When requirements are stable and well managed, the program’s cost and schedule become more predictable. With a clear scope and controlled change, there’s less rework, fewer change orders, and fewer surprises to affect time and money. This stability lets estimates be based on known work, keeps the baseline intact, and improves risk assessment, so funding and milestones can be forecast with greater confidence. The other statements don’t fit because changes in requirements do impact cost and schedule, funding is tied to the procurement plan, and simply emphasizing cost without considering delivery realities isn’t a reliable guarantee.
