Distinguish between project portfolio management and project management.

• A. Portfolio management plans, executes, and controls a single project within constraints.
• B. Portfolio management selects, prioritizes, and governs a set of projects to maximize organizational value; project management plans, executes, and controls a single project within constraints.
• C. Project management selects, prioritizes, and governs a set of projects.
• D. Portfolio management focuses on day-to-day project execution.

Answer: (D)

The key idea is that portfolio management deals with multiple initiatives at once, focusing on strategic value and alignment, while project management concentrates on delivering a single initiative within its constraints.

Portfolio management selects, prioritizes, and governs a set of projects to maximize organizational value and ensure resources are allocated where they contribute most to strategy. It provides governance, oversight, and funding decisions across many projects.

Project management, by contrast, plans, executes, and controls the work of one project—watching its scope, schedule, cost, and quality to meet defined constraints.

So the best description is the one that captures portfolio management as handling a group of projects to maximize value, alongside project management handling a single project’s delivery. The other descriptions misplace the scope (single project versus portfolio) or the focus (strategic governance versus day-to-day execution).
