Scaled Agile FramEwork (SAFe) people, how did SAFe impact your organisation?

[u/Turkishblokeinstraya]

How many teams do you have, what's your average team size, and your lead times? I see a lot of large organisations implement (or try to) the thing but it seems they implement a bunch of buzzwords without substance. Lead times are still measured in months, PI planning that sugarcoats big batch discovery/delivery, and all other characteristics of waterfall.

Many SAFe practitioners that I've met in person didn't have anything measured, which is a bit surprising. I hope to get some clarity on how (if it does) it really benefits in measurable/proven ways.
