Corporations running at the scale where SAP operates are so huge that basically nobody fully understands them or really know what they're doing (but they're also big and entrenched enough that they don't need to - inertia, institutional memory, brand awareness and existing product-market fit will do the job as long as the market doesn't radically shift from under their feet, cf. disruption). Seen through that lens it's no surprise that cargo culting is so widespread, or that huge businesses like SAP, Oracle and McKinsey can make massive profits off of essentially giving upper management in big corporations the reassurance that 'they are doing what everyone else is doing' so hopefully the good times will keep rolling.
