For me, it is a lot of fun to take a bunch of numbers, crunch them, and get the results that ultimately make an impact on our business. Sometimes in supply chain management, it can take one to two years of planning for the results to show up. We're seeing that right now: two years ago we changed a lot of process systems in our structure, what people did what, etc. All those things were happening at once and it was really chaotic and uncomfortable to go through, but now we're really seeing the fruits of that labor. It's fun to see the results and see things turn out like you expected.
