In my previous role as an Amazon Senior Learning Manager, I had two types of clients. I had the associates who worked in the actual process paths, and I had the senior managers that actually held accountable all the building throughput. In this one particular instance, we had what's called ambassadors. These are people that I train to train other people in the building in each process path in the building. We had a particular senior operations manager who had issue with us choosing ambassadors who weren't the fastest workers in the building. He had this thought that there was a direct correlation between those who worked the fastest and those who taught the best. I had to do what we called an Amazon have backbone and disagree and commit. So what that meant was, is I had to tell him that just because someone is the fastest doesn't mean that they're the best at that job, and that sometimes the best teachers are those who have the best quality. So I showed him.
