Controls to minimize risk and maximize value for the IT portfolio should be the most important consideration when conducting a review of IT portfolio management, because they ensure that the IT portfolio aligns with the business strategy, objectives, and priorities, and that the IT investments deliver optimal benefits and outcomes. Assignment of responsibility for each project to an IT team member, adherence to best practice and industry approved methodologies, and frequency of meetings where the business discusses the IT portfolio are also relevant aspects of IT portfolio management, but they are not as important as controls to minimize risk and maximize value.
