Comprehensive and Detailed 250 to 250 words of Explanation From Exact Extract of SAFe 6.0, including the SAFe Release domains:

In SAFe 6.0, Enablers are work items that support future business functionality by addressing architecture, infrastructure, compliance, or exploration needs. At the Program level, Enablers are essential for sustaining flow, reducing technical debt, and enabling the Continuous Delivery Pipeline. The Release Train Engineer (RTE) works closely with the System Architect to ensure Enablers are properly identified, prioritized, and planned within the Program Backlog and Program Increment.

The System Architect has primary responsibility for defining and evolving the architectural runway and identifying the technical and architectural Enablers required to support upcoming features. The RTE facilitates collaboration, alignment, and decision-making to ensure these Enablers are visible, sequenced appropriately, and balanced with business features during PI Planning and execution. This partnership is critical to maintaining system integrity and long-term agility.

Solution Management operates at the Large Solution level and focuses on solution vision and capabilities, not ART-level Enabler prioritization. Product Owners prioritize Team Backlogs, not Program-level Enablers. Development Manager is not a defined SAFe role.

By working with the System Architect, the RTE helps the ART maintain architectural integrity, improve flow, and reduce risk, which directly supports the SAFe Release domain’s goals of predictable, high-quality value delivery.
