Many corporations have loads of procurement people. On holding level, domestic level and they all try to procure & source as clever as possible. Annual savings can be made on every item that will be procured but how do you save costs after a few years?

Just outsource the central procurement teams and connect the local procurement people to the external sourcing & procurement company. They bring the value back to corporations. SG&A costs are quite often related to Finance & ICT and sourcing is very actual of those services. Procurement & HR departments should be reviewed to.
