When I was working with managers at LinkedIn it was clear that “the D” was deeply engrained in their culture. “the D” is the Directly Responsible Individual - the person who is responsible for getting the thing done. Getting the notion of “the D” or “the DRI” embedded in your management culture will make a lot of things just go better. Take a look.
I’m not usually a fan of speed for its own sake - it can turn into rather frenzied, unconscious action - but this make a good case: doing things quickly lowers the expected cost of doing them which has a bunch of knock-on effects. Worth a read.
