We've had good luck using the Ariba Discovery functionality and locating suppliers quickly. I had a beverage commodity Manager in the Marketing group tell me how impressed that he was in a recent bid that we could find speciality beverage companies so quickly and easily using this tool. It definitely has saved my group time at Pilot.
We ran into an issue with a supplier that went belly up on us.
This immediately disturbed our supply chain for a particular item needed for new store openings.
We used Discovery to try and identify a new supplier that could supply the product needed for our stores.
Not only did we find a supplier, we found the supplier that bought the patten on the item from our old supplier.
A happy ending to a frustrating situation.
