@shaknais The quote about external assurance does not prove there was no internal QA, and you should understand that. Asking for additional independent QA is normal if things go badly wrong, but doesn't support your amazing assertion "all changes go straight to production". Dumping diagrams about an *ERP* system has nothing to do with the systems used to deliver core services, and there's a world of difference between talking about pushing changes directly into production (your claim) and integration testing of an ERP. Your original claim said "apparently" but you still haven't pointed at a clear source for it, and ""all changes are straight to production".
