The document discusses measuring procurement's performance and calculating savings. It covers:
1) The challenges of accurately measuring procurement savings, as focus on savings can incentivize deliberately misleading reporting through methods like carrying forward savings from prior years.
2) The need to separate external factors like currency fluctuations and market movements from internal procurement actions to identify true savings.
3) Different approaches for measuring one-time vs recurring spend, and ensuring negotiated savings are captured in actual spending to benefit the bottom line.
4) The importance of a balanced set of metrics beyond just savings, including quality, operational performance, added value, and people factors.
