Which type of analysis would be most helpful to a portfolio manager at an organization that is comparing its current portfolio components with a new strategic direction?

Force field analysis evaluates driving and restraining forces around a specific proposed change, not the fit between portfolio components and a strategic direction.

Gap analysis identifies differences between current and desired states generally, but capability and capacity analysis is the more specific PMI-recognized tool for portfolio-to-strategy alignment assessment.

Strategic change analysis is not a distinct, recognized portfolio analysis technique for comparing components against strategic direction in PMI's framework.

Capability and capacity analysis inventories the organization's existing competencies, resource availability, and execution bandwidth, then compares them directly to the requirements of the new strategic direction. This comparison reveals which portfolio components are still viable, which need to change, and where new investments are required.
