Alexa Stefanko led one of the most dramatic improvements in a team I've seen. We talk about a set of changes we introduced at Gremlin, including the Single Threaded Owner model, the introduction of product metrics, and setting up an "API" between local teams and senior leadership. Alexa also talks about her move to being a director, the differences between medical and tech leadership, and how animal training has influenced (and not influenced) her approach with people.
