The Release Train Engineer (RTE) plays a crucial role in facilitating the Agile Release Train (ART) events and processes, and one of their responsibilities is to ensure the readiness of the Program Backlog for the next Program Increment (PI) planning. According to the SAFe framework, the RTE should coach Product Management and the System Architect to include Program Backlog refinement into their regular cadence2.
This ensures that the backlog is continuously groomed and ready for the upcoming PI planning events. The Program Backlog is a holding area for upcoming Features intended to address user needs and deliver business benefits for a single ART, and it also contains the enabler features necessary to build the Architectural Runway1. Refining the backlog is a continuous process that involves research activities and active collaboration with various stakeholders, managed through the Program Kanban system1. By coaching Product Management and the System Architect to refine the backlog as part of their regular cadence, the RTE helps maintain a steady flow of backlog items that are well-understood, prioritized, and ready for implementation, thereby optimizing the Program Backlog readiness for the next PI12.
