In the PMBOK® Guide and the Standard for Portfolio Management, the primary purpose of a portfolio is to ensure that the aggregate of its components (projects, programs, and other work) is managed to achieve strategic objectives.
Why Choice D is correct:
Measuring Strategic Value: Success at the portfolio level is not just about whether individual projects were completed on time or under budget; it is about whether they delivered the expected business value.
Aggregate Benefits: The executive committee looks at the " big picture. " By aggregating (combining) the benefits realized from all active and closed projects, the committee can determine if the organization is actually achieving the ROI (Return on Investment) or growth it originally planned for.
Portfolio Balancing: If the aggregated benefits are lower than expected, the committee may decide to terminate underperforming projects or shift resources to more promising ones.
Analysis of other options:
A (Charter the strategic objectives): This is part of the Initiating or Strategic Planning phase. While objectives are needed to define success, the act of chartering them does not " evaluate " whether that success has actually been achieved during a review.
B (Control environmental changes): Environmental factors (EEFs), such as market shifts or government regulations, are often outside the organization ' s control. A committee monitors them, but controlling them is usually impossible, and it is not a metric for evaluating portfolio success.
C (Monitor changes continuously): While monitoring changes is a key activity in Integration Management, it is a process, not an outcome. It helps identify risks or scope issues, but it doesn ' t provide the metric needed to evaluate the overall success of the portfolio ' s investment.
Key Concept: The Project Management Institute (PMI) emphasizes that Portfolio Management (Choice D) focuses on doing the " right work. " The ultimate measure of whether the committee chose the " right work " is the Benefits Realization—the tangible and intangible value that is harvested by the organization once the project deliverables are put into use.
