Understand how the money is spent, with whom, and why. Review supplier performance and understand how your own procurement department is performing.
Monitor how supplier cost evolves over time, initiate competitive bidding whenever needed, and make sure you are not paying too much for anything. Understand delivery and quality issues with your supplier base and drive corrective action to lower cost of poor quality.
Procurement is hard work and doing it well is almost impossible without proper tools. Without the right tools your team will struggle with day-to-day manual operations, not to mention having the right information in usable format for optimal decision making. Giving your team proper tools for doing their jobs will give them an opportunity to become a strategic asset, while allowing you to keep your team fully accountable for the results of their work.
