Steve Blank does a nice job of comparing Design Thinking to Lean Startup.
Steve makes the point that Design Thinking is optimized for getting it right before making a big bet.
Also important to understand that urgency may not be associated with Design Thinking. You can create urgency by building a minimum viable product within a timebox. Let's say the team only has three months to create a working product. Now that should cause the team to work with pace and tempo.
