Chief Wrench, BUMSONTHESADDLE
Your primary job as a leader is to hire the right team, and then to spend time inspiring this sense of purpose. Help people understand the impact of their work, and speed will follow.
Crafting a sense of purpose is different than creating urgency.
A team with a high sense of purpose can look a lot like a team with a high sense of urgency. Output is high. People are engaged. The critical distinction is that what you do as a leader has very little overlap.
