Which statement best describes the project manager's role in terms of trade-offs?

• A. Focus on time only
• B. Manage the trade-off between performance, timeliness and cost
• C. Increase project scope
• D. Manage the trade-off between scope and risk

Answer: (B)

A project manager’s job is to balance competing constraints: the deliverable’s performance (scope/quality), the schedule (timeliness), and the budget (cost). This option is the best because it recognizes that these three elements are interdependent: pushing for faster delivery usually means higher cost or lower performance, while aiming for higher performance typically requires more time and money. The manager must negotiate and optimize these trade-offs to meet the project’s objectives and stakeholder expectations.

The other statements don’t capture this balance. Focusing only on time ignores cost and performance. Increasing scope isn’t about balancing the standard constraints. And trading off between scope and risk shifts emphasis away from the core time-cost-performance trade-off.
