Statements from this episode (31)
Caldwell: Musk's aggressive deadlines force teams to prioritize critical paths
“When Elon sets, like, super aggressive targets, the goal is actually to get the team to think really deliberately. There's a thousand things that have to happen, but a hundred of them cannot be done in six months, so we have to go attack those hundred things.”
Luzsicza: US missile defense faces supply shortages and slow manufacturing
“Being somewhat foreign to the missile industry, I realized we don't have enough. They cost too much, and we can't make it fast enough.”
Luzsicza: Galadyne will apply commercial liquid propulsion to missile systems
“With my background being purely in liquid propulsion across SpaceX, and even at UCLA launching liquid rockets, there's a very real way to apply this technology to the missile system, and we're gonna go do it.”
Caldwell: The mining and minerals industry is massively software deficient
“At Tesla, what became very apparent is that the industry is massively software deficient”
Caldwell: Refineries and mining must leverage automotive autonomy and humanoid robots
“And what we've landed on is that you have to go full bore kind of like leveraging the advances in autonomy in automotive and humanoid robots to go and apply that to refineries and to mining operations.”
Caldwell: Flat organizations are hypercritical for rapid information flow
“I think the flat orgs is, is hypercritical, right? You need information to flow as quickly as possible. You need to democratize access to information. And that's really the purpose of flat organizations.”
Luzsicza: High decision velocity accelerates development and production cycles
“You need leaders across that flat org that are able to make decisions really quickly. I think decision velocity without using a buzzword is, is very, very important. With high conviction leadership who can make strong decisions you increase the pace of develop…”
Caldwell: Teams cannot wait for full information before making decisions
“You can't wait to have all of the information available to make decisions, right? And oftentimes you won't find out if the decision is correct or not until you've made it, tried it, and then iterated really quickly”
Caldwell: Data silos naturally form when teams hit 100 people
“And that doesn't really happen in teams of, like, 10, 20, 30 people, but it does start to happen once you get into teams that are a hundred people or more.”
Caldwell: Mariana Minerals removed internal access controls on engineering data
“Everything is like web app posted their access controls are basically gone at least internal to the company. When it comes to being able to see like the core engineering information, it does not live on a hard drive somewhere. It does not live in an email that…”
Caldwell: Capital projects require tracking the full history of all decisions
“There are insane data silos between the engineering groups and the procurement teams and the construction teams. And so you have to build like a net new operating system that ensures that like the history of every individual decision is tracked and everyone ca…”
Caldwell: Deploy small SWAT teams to address critical paths in parallel
“You have to, like, set up, you know systems that enable you to mobilize, like, core groups of teams to go after critical paths while also not letting the next decision kind of fall behind. And a lot of that is around having, you know, little SWAT teams that ar…”
Luzsicza: Daily email updates build team transparency and individual accountability
“High signal, low noise email updates on particularly with things related to critical path are extremely important to do one, you know, give, The information to a broader set of folks. ... And for that person to take ownership and send, you know, high, high cad…”
Caldwell: Daily shift passdowns instill manufacturing discipline in R&D
“If you want to drive like process development and R&D towards thinking about it as a manufacturing type process, the best forcing function is at the end of the day, you have like the equivalent of a shift passed down, which is you say, here's what we did. Here…”
Luzsicza: Galadyne targets launching a rocket into the air by June
“We all sat down and we set this very ambitious schedule to go get a rock in the air by June.”
Luzsicza: Mission alignment prevents long hours from causing burnout
“A lot of this comes back to the, to how mission aligned the company is, or how strong the mission of the company is. It's, it doesn't feel like working if it's fun. And particularly for folks who are so aligned with the mission of the company obviously in Spac…”
Luzsicza: Defense tech must recruit talent from commercial space companies
“The reality is, is in, in, in my case, there's so much talent that's living at SpaceX. There's so much talent living in Rock Lab, Firefly, and Relativity that need to come work this problem set too.”
Caldwell: Organizational churn and lack of progress cause burnout, not long hours
“I think the thing that actually causes burnout is churn and like a lack of feeling like you're making progress physical.”
Caldwell: Setting aggressive targets without a technical path demoralizes engineering teams
“As long as you're setting goals that are aggressive, but are possible, like, that has to be, like, it has to be in the realm of possibility then, you know, it doesn't, like, if you go super, super aggressive on targets that have no actual technical path toward…”
Caldwell: Tesla added organizational structure after reaching 130,000 employees
“In, in the early days, the, like, it was flatter, obviously, as you would expect, because once you get to like a 130, a 140,000 people you know, you have to start to layer in some structure.”
Luzsicza: SpaceX skipped the V2 design cycle on Starship Booster
“Booster was a little bit ahead of ship, the ship team in terms of their V three design. They kind of skipped V two for Booster. They went from V one to V three.”
Luzsicza: Questioning requirements creates simpler, faster, cheaper hardware
“Question every requirement, because what that does is it enables your requirements set whenever, you know, an engineer steps in to go actually design the hardware to be, you know, enabled to design a very simple solution and simple as fast, simple as cheap.”
Caldwell: Construction schedules should be built bottom-up from discrete tasks
“On construction, you need to boil it down into specific subsets of tasks that are, you know, actually torquing bolts and actually like welding out seams to build that up into like, what does the schedule actually need to be instead of doing like top-down asses…”
Caldwell: Infrastructure projects lack manufacturing-style progress tracking
“That level of like measuring and measuring against goals and setting targets just doesn't happen in this like large scale infrastructure ecosystem.”
Luzsicza: Blanket vertical integration for hard-tech startups is naive
“This blank slate, idealistic, we're going to vertically integrate is like, I think almost naive in a way. Like, vertical, vertical integration is not easy.”
Caldwell: Startups should only vertically integrate if their existence depends on it
“You should not be vertically integrating just because you can save five percent or 10% or 20, even 50% on a subcomponent that does not kind of check the box of like, does the company exist or not?”
Caldwell: Pure-play SaaS companies struggle to penetrate the mining sector
“Software companies that sell to mining companies have a very, very hard time penetrating the sector because the issue is the, like the rate of uptake of software and of technology is actually gated by what would be the customers if you were a pure play SaaS co…”
Caldwell: Tesla requires eight to ten interview conversations for engineering hires
“The, like the key part of the hiring process at, you know, Tesla at least, and I'm sure it's SpaceX is the like technical evaluation, it goes quite deep. And so there, you know, you're going to talk to six engineers. If you're applying for an engineering role,…”
Luzsicza: Most critical SpaceX engineers on Starship and Falcon are former interns
“There, I think the overwhelming population of folks that are doing so much of the critical work on Starship, Dragon, Falcon even are intern conversions.”
Caldwell: Engineers should see end-to-end project iterations before starting startups
“I wouldn't go and start something until you have, like, been able to sit around a project that you have seen go end to end, and then done that multiple times. That enables you to see how, like, how much better can you get with each iteration of, like, from con…”
Caldwell: Founders should master technical skills before company-building skills
“You want to have as strong of a technical basis before you go and have to learn all of the company building side of things. And so making sure that you're kind of like over indexing on the technical side before you go and kind of sign up for figuring out how t…”
