When classifying your suppliers (supply items) as ABC, how should you best manage the "A" suppliers (or supply items)?

1. Focus on parts standardization to see if you can consolidate some of these items into a common supply item suitable for use by all

2. Form a strategic partnership with your supplier

3. Find a supplier who could handle a significant portion of your tail spend and outsource this portion

4. Encourage your user base (internal customers) to buy out of eCatalogs

5. Eliminate the "A" suppliers
