Short transcript excerpt where Elon Musk outlines a five-step approach to improving processes: (1) question and reduce requirements, (2) delete unnecessary parts, (3) simplify/optimize, (4) accelerate cycle time, and (5) automate — with a caution to apply steps in that order and to avoid automating too early.

First make your requirements less dumb. Your requirements are definitely dumb. It does not matter who gave them to you. It's particularly dangerous if a smart person gave you the requirements because you might not question them enough. No matter who you are. Everyone's wrong some of the time. Then try very hard to delete the part or process. This is actually very important. If you're not occasionally adding things back in you are not deleting enough. The bias tends to be very strongly towards let's add this part of process step in case we need it. You can basically make in case arguments for so many things. The third step is simplify or optimize the third step. Finally you get to step four which is accelerate cycle time. You're moving too slowly. Go faster but don't go faster until you have worked on the other three things first and then the final step is automate. I personally made the mistake of going backwards on all five steps multiple times. I automated, accelerated, simplified and then deleted.
