Delete It Before You Optimize It

Elon Musk's first rule: make requirements less dumb. Second: delete the step. Optimization is third — and most people start there.

Elon Musk's five-step improvement process is ordered deliberately, and the order is the insight.

  1. Make your requirements less dumb. Every requirement has an owner, and that owner is probably wrong about at least one thing, regardless of how smart they are.
  2. Delete the part or process entirely. If you are not occasionally adding things back in after deleting too aggressively, you have not deleted enough.
  3. Simplify or optimise. Only here, in third position, does the word 'optimise' appear — because optimising a process that should not exist is waste disguised as progress.
  4. Accelerate cycle time.
  5. Automate.

Musk's own admission is that he has personally made the mistake of going in reverse — automating first, then accelerating, then simplifying — and paid for it. Dara Khosrowshahi at Uber makes the same point from a different angle: when Uber's mobility business lost 85% of its volume overnight at the start of the pandemic, the response was not careful deliberation. It was top-down and fast — because a decision that is twenty percent off but made immediately beats a perfect answer that arrives after the window has closed. The process question and the decisiveness question are the same: are you spending time on things that should not exist?

Before optimizing anything, ask whether it should exist at all. If you cannot justify its existence independently, delete it. Only then simplify, accelerate, and automate — in that order.
