Final answer:
The true statements regarding project portfolios are B (projects within the portfolio support strategic goals) and A (projects may not have anything in common). Portfolios can contain both programs and stand-alone projects, and organizations can have more than one portfolio aligned to different goals. Options A and B are correct.
Step-by-step explanation:
When discussing project portfolios, it is important to consider how they support organizational goals and the compositional elements they include. The correct options from the provided list are:
B: The programs and projects within the portfolio support the strategic goals of the portfolio.
A: The independent projects in the portfolio may not have anything in common. While it's true that projects within a portfolio can be autonomous, they are typically aligned to broader organizational strategies.
Contrary to choice C, an organization can have multiple portfolios, each tailored to different strategic objectives. Choice D is incorrect as portfolios can contain stand-alone projects in addition to programs. Project portfolios are designed to maximize returns and minimize risks, akin to mutual funds in finance, yet it's not guaranteed they'll ensure economic success. Portfolios showcase the range and depth of professional and academic experiences and skills, which is important for employers seeking to understand a candidate's capabilities.
