There's nothing wrong with applying agile on mature orgs per se. With all due respect, technical software people usually fail miserably at understanding what deploying ERP is. It's by no means software project. The "ERP" could be a huge physical book with all required templates even if very inefficient one, nevertheless deploying such "ERP" would still face *exactly* the same problems. Deploying ERP is first and foremost business transformation. All ERP deployment horror stories that I have some inside info on always revolve around reluctance of business to transform and instead attempting to contort ERP to fit some undefined shape. Deploying ERP painfully highlights all the spots where business processes are undefined, overlapping or flat out useless. Those processes need to be cleaned up, there's no way around that. Every information system follows SiSo/GiGo (Garbage in - Garbage out) principle. Humans can apply common sense heuristics and do reasonable things given garbage data. Information systems cannot. That's the beauty and horror of deploying an ERP. If management is actually willing, it's a perfect opportunity to streamline business processes, but if it is managed as some software deployment over existing business - you get horror stories, reduced efficiency and maintenance hell on top.
