Last place I worked tried to do SAFe (I think? They kept repeating it and had all the branding on the presentations). To me it seemed like the idea was to replace a dedicated project manager (or team of them) with a week-long meetingfest every 8 weeks where all the different teams tried to self-organize based on what the business' objectives were.

Apart from the colossal waste of time of those week-long "PI-planning" meetings, it was OK I guess...
