Effective portfolio management relies on defined, transparent criteria for project selection and prioritization to ensure alignment with organizational strategy and resource optimization. PMI-PMOCP highlights that a PMO professional should implement formal portfolio management processes, including documented criteria, scoring models, and decision-making frameworks. This reduces subjectivity and political debate, expedites decision-making, and fosters executive alignment and accountability.

While facilitating discussions (option A) or encouraging objective business case discussions (option C) may help, without an established process and criteria, subjective debates and delays are likely to persist. Informal relationship-building (option D) supports teamwork but does not address structural inefficiencies. Establishing portfolio management services that guide selection ensures consistent, efficient governance of projects.
