Which result is most likely when requirements are unstable?

• A. Negative impact on cost and schedule.
• B. No impact on cost and schedule.
• C. Improved cost accuracy.
• D. Faster procurement approvals.

Answer: (A)

Unstable requirements cause frequent changes, rework, and evolving expectations. When what needs to be delivered isn’t clear or keeps shifting, the team must continually redesign, recalculate plans, and obtain new approvals. Each change adds extra work, delays milestones, and increases resource use, leading to cost overruns and longer schedules. That’s why a negative impact on cost and schedule is the most likely result. Quick, unchanging plans would be necessary for improved cost accuracy or faster procurement, and claiming no impact overlooks how uncertainty typically drives delays and added expense.
