I was lucky to I have a great experience w/ agile and scrum. We were a bit team (~70ish devs) broken down into teams or 4-6. Each team had a PO (tech lead) and a "Scrum Master" . The scrum masters job was to make sure managers weren't micromanaging the teams. If they had issues or questions they had to go through the Scrum Master. Only thing we all hated was release planning because it was 1 week of trying to make managers happy with delivery dates.
