When faced with software problems I used to ask, How can we accelerate the feedback loop?
After rereading The Lean Startup and one particular footnote I now ask, How can we compete on the basis of speed? A broader question that encompasses the whole company and the possible redesign of the organization.
Of course, Design needs to be part of the success equation.
Design + Speed = Success*
* All other parameters held constant for success. That means the leader would have to be working at the catalyst leader level.
