I've been through the agile process at 5 different companies, and it has never been successful. My biggest issue is with the people who are brought in to implement it. The scrum masters always try to spin the whole thing as a positive for both the development team and the business. Both the team and the business's management are supposed to be disciplined. But the scrum masters always wind up being scum masters, always bowing to the will of the business's management. Meanwhile the team is left with nobody to defend their right to have the process respected. The primary selling point is always the removal of the "old waterfall method". And yet every single sprint, 20-40-80 hours worth of "more urgent tasks" get dropped in without proper grooming or advanced planning. Whether or not other tasks get removed from the sprint to equalize the incoming work does nothing to alleviate the frustration. Every agile process I have seen always winds up being the same old bullshit of management having no discipline to actually follow the rules. We call it agile, but it's still just waterfall glossed over with a name - with none of the actual principles being taken seriously.
