OS2.0 SAFe Delivery Context (Master)
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.
