Kralic's Supply Matrix assumes that the purchase of non-critical items can be simplified by an automated process such as web ordering, supplier managed inventory or other means. However, when trying to impact expense or reduce cost we should: 1. Exploit purchasing power to minimize cost using leverage. 2. Always choose the lowest cost provider even if the supplier does not deliver on time. 3. Ensure delivery of the items by holding suppliers accountable. 4. Always trust and believe that you are obtaining the best possible price
