The executive committee of a company is reviewing its portfolios. Which of the following would be helpful to evaluate success?

Chartering strategic objectives is an initiation activity, not an evaluation method for assessing whether a portfolio has delivered its intended value.

Aggregate benefits realization measures the collective value delivered by all components within a portfolio against the organization's strategic objectives. This is the primary metric for portfolio success because portfolios are managed to optimize the total value and return on investment across all constituent initiatives.

Controlling environmental changes is an operational management activity and does not provide a measurable indicator of portfolio-level success.

Monitoring changes continuously is an ongoing process activity, not a success evaluation metric suitable for executive portfolio review.
