Spend that isn’t "under management" is difficult to analyze because information is scattered throughout the organization, in very different formats and varying levels of quality.
The average organization has only 55-60% of its spend under management, while best-in-class performers manage close to 85%. If a business can achieve 5-10% savings on spend under management, an increase from 55% to 75% can generate an additional 1-2% of savings — and put procurement on a path to exceed typical annual savings in the range of 7-10%.
