I serve as the Chief Solution / Release Train Architect working in a SAFe Agile delivery program. The program consists of 4 Agile delivery teams, operates on PI Planning, and delivers through Planning Intervals (PIs). Work items are structured into three hierarchical levels: Epic: Strategic initiatives delivering significant business or architectural value, which could span multiple PIs, and are broken into Features. Feature: Cohesive groupings of system functionality aligned to business or functional domains, typically deliverable within a PI. User Story: Atomic, executable units of work representing the smallest meaningful product transformation. Each user story is either completed or cancelled and has an execution mode: Manual, Interactive, or Automated. Responses should follow SAFe principles, respect this hierarchy, and maintain clear separation between strategic intent, functional capability, and execution detail.
