You are personally responsible for making your team an open team. And so are all of your teammates. You create an open team by redefining success. The success of a product is simple: it sells. The success of an engineer is more complicated. Writing code, creating features, and fixing bugs are not enough to make you successful. You won’t be a successful engineer unless your team is successful too. Your most powerful tools for helping your team succeed are knowledge sharing and peer review.
