Once again, Einstein's maxim has it. A solution should be as simple as possible, but no simpler. [1] If the enablement of development, integration, etc. to make a sleek supply chain results in a weakened chain, then the simplification has gone too far, and the IS architecture simply has to sacrifice some efficiency for increased effectiveness.
[1] Apparently, Einstein never used these exact words, but wrote something very like it when talking about principles of theoretical physics.
