What is the best way for the Release Train Engineer to show progress of work in the cur-rent Program Increment (PI) to management?

The best way for a Release Train Engineer (RTE) to show progress of work in the current Program

Increment (PI) to management is to conduct a System Demo. This is supported by the SAFe

documentation which states that the System Demo is an integral part of the PI, providing an

opportunity to inspect and adapt the solutions being developed1. It serves as a platform to showcase

the achievements of the Agile Release Train (ART) and allows stakeholders to provide feedback1. This

event aligns with the principle of transparency and provides a clear, objective measure of progress1.
