The approach we take to building the Facebook app is based around three adjectives: trustworthy, people-centric and unified. In this episode, Pascal talks with Maria who is a director of engineering for product architecture and product excellence. They discuss what it means for a culture that is known for being driven by metrics to become more people-centric. What are examples of metrics that are aligned with people goals and when do they fail to capture them? Tune in to hear the answers to these questions and much more. Got feedback?
