Process is king in mature industries where profits are extracted from scale and volume. Anything outside of standard process is expensive. If there is no external entity to bear the cost, then this cost is to be minimised.

You and I may not agree with this approach, and the formula is somewhat different for creative industries, but numbers don't lie. It's always a compromise between agility/adaptability and cost when in a production line.

A main function of an ERP system like SAP is to maximise this extraction.
