Elon Musk's first principles and five-step algorithm

Elon Musk has described two methods that are often cited outside rockets and cars. One is first-principles reasoning: break a problem down to its fundamental truths, such as what a product is made of and what those materials cost, and reason up from there instead of copying how others do it. The other is a five-step order for improving a process: question each requirement, delete, simplify, speed up, and automate last. This page explains both from his TED and Wired interviews and a 2021 interview on a Starbase tour, and shows how to apply them to an ordinary business.

First principles instead of analogy

In his 2013 TED interview with Chris Anderson, Musk said a good framework for thinking is physics, in the sense of first-principles reasoning: "boil things down to their fundamental truths and reason up from there" (TED transcript), as opposed to reasoning by analogy. He described analogy as copying what other people do with slight variations, and said people need it to get through daily life; the physics approach is for when you want to do something new. In the same answer he added a second habit: pay attention to negative feedback and ask for it, particularly from friends.

A cost floor from raw materials

In a 2012 Wired interview, "Elon Musk's Mission to Mars", Musk explained how he applied this to launch prices. He asked what a rocket is made of (aerospace-grade aluminium alloys, some titanium, copper and carbon fibre) and what those materials are worth on the commodity market. He said "the materials cost of a rocket was around 2 percent of the typical price" (Wired), compared with roughly 20 to 25 percent for a Tesla car, and concluded that a much cheaper rocket should be possible.

He also named what he saw in the gap: an aversion to risk that kept decades-old components in use, and outsourcing through several layers of subcontractors, each adding its own profit.

The same arithmetic works on smaller things. A roastery paying 0.92 per printed coffee bag can weigh the bag, price the laminate and the valve, and find that the materials come to a small share of the price. That doesn't prove the price is wrong; converting, printing, setup and margin are real costs. It shows which layers to ask about, for example by getting a quote directly from a converter.

The five-step algorithm

On a 2021 tour of SpaceX's Starbase site with Tim Dodd (Everyday Astronaut), Musk walked through a five-step process, stressing that the order matters. The steps below follow the interview's caption transcript and Entrepreneur's edited transcription of it.

1. Make the requirements less dumb. He said requirements are definitely dumb, no matter who gave them, and are most dangerous when they come from a smart person, because you may not question them enough. Each requirement should come with the name of a person who takes responsibility for it, not a department.
2. Delete the part or process step. The bias runs toward adding things in case they're needed. He said that if things aren't being added back in at least 10 percent of the time, not enough is being deleted.
3. Simplify or optimise. Only third, because a very common error of a smart engineer is to optimise something that should not exist.
4. Accelerate cycle time. Go faster, but only after the first three steps.
5. Automate. Last. He said he had made the mistake of going backwards through the steps on the Tesla Model 3, automating before deleting.

Fortune's 2023 report on Walter Isaacson's biography lists the same five steps in the same order, says they became known as "the algorithm", and describes the early plan to automate every task at Tesla's Fremont factory from the outset, a decision that was later reversed.

In an office, the order changes what gets fixed. An agency about to buy a tool that copies intake forms into its CRM would first ask who needs each of the form's fields, delete the re-entry step altogether, and only then decide what is left to automate.

How to apply it to your own business

1. Pick one cost you take as given and write how it is usually justified ("that's what it costs in this trade").
2. Break it into inputs that have a market price, price each with a source, and add up the floor.
3. Compare the floor with today's price and list what each layer of the gap pays for; mark which you know and which you're guessing.
4. For a slow process, list every requirement and step with the name of the person who owns it.
5. Delete what nobody can defend, simplify what's left, then speed it up.
6. Automate only what survives, and check later what had to be added back.

What the sources say, and what they don't

The first-principles description and the advice on negative feedback come from the TED transcript; the rocket materials example from the Wired interview. The five steps come from the 2021 interview (the video, and Entrepreneur's edited transcription), and Fortune's account of Isaacson's biography; we have not read the biography itself. The quoted phrases are from TED, Wired and Fortune. The coffee bag and agency examples, and the application to office work, are our own.
