The Release Train Engineer (RTE) plays a crucial role in facilitating events and processes that support

relentless improvement within the Program Increment (PI). According to the SAFe framework, one of

the primary responsibilities of the RTE is to “facilitate ART practices and PI execution” and to "drive

relentless improvement"1.

The Inspect and Adapt (I&A) event is specifically designed as a significant event held at the end of

each PI, where the current state of the Solution is demonstrated and evaluated. Teams then reflect

and identify improvement backlog items via a structured problem-solving workshop2. This aligns

with the SAFe principle of relentless improvement, which is a core value and a dimension of the

Continuous Learning Culture competency within SAFe2.

During the I&A event, all ART stakeholders participate along with the Agile Teams. The result is a set

of improvement backlog items that go into the ART Backlog for the next PI Planning event, ensuring

that every ART improves every PI2. This structured approach to reflection and problem-solving is

what makes the Inspect and Adapt event a key mechanism for the RTE to support relentless

improvement for the Program Increment.
