Strategic Portfolio Management (SPM) platforms connect top-down strategy — investment themes, OKRs, capacity targets — to bottom-up execution in programs, projects, and agile release trains. Core capabilities include portfolio and program hierarchy modeling, capacity and demand planning, financial planning with benefits realization tracking, scenario analysis and trade-off comparison, roadmap visualization, and integration with downstream execution tools (Jira, Azure DevOps, ServiceNow). SPM is the successor category to legacy Project Portfolio Management (PPM); Gartner rebranded the MQ to reflect the shift from project-tracking to outcome- and value-stream-centric portfolio governance.
