Portfolio epics are managed according to the Lean Portfolio Management (LPM) model, which is an agile framework for managing projects as part of an overarching strategy. This framework emphasizes tight collaboration between stakeholders, rapid feedback loops, and iterative planning and delivery. The primary way Portfolio Epics are managed is through the creation of Agile Release Trains (ARTs). ARTs are cross-functional teams that are responsible for delivering value to stakeholders in the form of projects, services, and products. The Portfolio Epic is used to set the overall vision and roadmap for the ART and guide the team’s progress.
