As the guilty analyst responsible for issuing that initial benchmark, I am curious to hear how well it's holding up -- particularly for those companies that have been applying strategic sourcing and compliance methods to a particular spend category for a number of years. My hunch is that the percentage cost reduction narrows overtime; but that savvy sourcing groups find other ways to drive value into that spend category through better demand management and joint waste reduction efforts (i.e., lowering processing costs and errors) with their supply partners. Or, in other words, they truly get spend under management.
Looking forward to this session at Ariba LIVE. Thanks for sharing.
